Abstract
Globally and locally, conservationists and scientists work to inform policy makers to help recovery of endangered sea turtle populations. In Fiji, in the South Pacific, sea turtles are protected by the national legislation because of their conservation status, and are also a customary iTaukei resource. Centered on our interview-based study at Qoma and Denimanu villages, parallel management systems coexist, where both the (written) national legislation and the (unwritten) customary iTaukei rules determine the time and the quantity of sea turtle harvest. In addition, non-governmental organizations and academic institutions may influence local sea turtle management by providing scientific awareness and helping divert the economic values from the meat to the living animal. We suggest that the government and non-governmental organizations emphasize community management of sea turtles, and work alongside the customary chiefs and their fishing clans to understand the real harvest (eventually by allowing quotas) and to monitor the recovery of South Pacific sea turtles in Fijian waters.

Introduction
Sea turtles are an imperative component of global biodiversity and numerous societies around the world (Arthur et al. 2008; Brikke 2009). Sea turtles cultural significance varies across the world, although a high cultural value may not deter a wide scale commercial trade (Allen 2007). In 1982, the International Union for Conservation Nature Red ListFootnote 1 classified all sea turtle species as endangered, except for the vulnerable loggerhead turtle (Caretta caretta) and the data deficient flatback turtle (Natator depressus). Fourteen years later, in 1996, the hawksbill turtle (Eretmochelys imbricata) and the Kemp's ridley sea turtle (Lepidochelys olivacea) were reclassified as critically endangered due to the overall decline driven by unceasing exploitation and other factors (Motimer and Donnelly 2008; Wibbels and Bevan 2019). Temporal investigation into the ecological significance and biology of sea turtles has informed an increased scale protection at the global level, with multilateral and regional agreements and national laws to protect sea turtle species across their range of distribution. Some of the notable global agreements include the Convention on the International Trade of Endangered Species of Wild Flora and Fauna (CITES), first signed in Washington in 1973, and the Convention on Migratory Species of Wild Animals (CMS), first signed in Bonn in 1979. In the South Pacific, the more recent regional guideline is from the Secretariat of the Pacific Regional Programme (SPREP) Regional Marine Species Program 2022–2026.Footnote 2
Status of sea turtle research in Fiji
Fiji waters are inhabited by four of the world’s seven sea turtle species; the green (Chelonia mydas), hawksbill, loggerhead and leatherback (Dermochelys coriacea) turtles (Piovano and Batibasaga 2020). Of these species, the green and the hawksbill turtles nest and forage in Fiji (Piovano et al. 2019; Prakash et al. 2020). The hawksbill turtle nests almost all-year round but has peak nesting in January, followed by a peak hatching in March (Prakash et al. 2020). Single paternity in Fijian hawksbill turtles was recently suggested based on genetic studies (Prakash et al. 2022). The origin of the green turtles foraging in Fiji ranges from Australia in the West to French Polynesia in the East and, based on the only two investigated foraging grounds of Yadua and Makogai Islands, the American Samoa management unitFootnote 3 is the primary contributor (Piovano et al. 2019 and review therein). Seasonal recruitment is influenced by seawater temperatures and mostly occurs in summer (Piovano et al. 2020). The juvenile green turtles have well-differentiated morphological traits (Álvarez-Varas et al. 2021), are present in shallow coastal waters (Papale et al. 2020), and their mixed diet has a strong invertebrates component (Piovano et al. 2020).
Sea turtles are long living, slow maturing species, which have a high mortality rate as hatchlings and juveniles (Bjorndal 1985; Hoorn 2016). The ecological importance of sea turtles is linked to their feeding habits and highly migratory behavior ranking them as ecosystem engineers and keystone species (Allen 2007; Lovich et al. 2018). Feeding habits of sea turtles reduce jellyfish population and corallivores, reduce nitrogen in seagrass meadows, and increase the disintegration rates of mollusk and transferring minerals within and between the marine ecosystems (Bouchard and Bjorndal 2000; Lal et al. 2010). Moreover, on nesting beaches, sea turtles’ eggs introduce nutrients into beach ecosystems and contribute to stabilizing sand dunes critical for their reproductive success (Lovich et al. 2018). Nutrients that remain in the nest chamber after hatching contribute organic matter that feed bacteria, fungi, ants and crabs, among others (Dodd 1988). Nest contents can also be consumed by predators or absorbed by plants (Fowler 1979). Sea turtles further serve as dispersal agents across the vast migratory paths they travel between nesting and foraging grounds transporting nutrients, energy, and marine fauna and flora (Bouchard and Bjorndal 2000; Allen 2007). In addition, they may serve as a pathogen or parasite host as well as substrates for epibiontsFootnote 4 (Allen 2007).
Cultural background and traditional knowledge of sea turtles in Fiji
For millennia, sea turtles (vonu) and the iTaukei (indigenous Fijian) communities interacted, resulting in sea turtles being embedded in the iTaukei culture as totems, spiritual deities, myths and chiefly tributes (Williams 1898; Morgan 2007). In pre-colonial times, sea turtle harvest was regulated by chiefsFootnote 5 and the turtles capture was limited to a selected group of traditional fishermen from the traditional fishing clans (gonedau). These fishing clans had a strict division of labor among the fishers, canoe makers and net makers. Women did not participate in sea turtle hunting because customarily, it was taboo for them to be associated with turtle hunting. Additionally, in a traditional setting, iTaukei participate in a customary division of labor where men captured sea turtles for their chiefs while women would glean or target small fishes in nearby coastal areas. Specialized fishing nets called lawasau (Veitayaki 1994) were used. The custom of turtle net making was highly institutionalized by the gonedau families from a delegated clan, who made nets of coconut (Cocos nucifera) sinnet (magimagi) or Hibiscus tiliaceus (vau) and presented them to the paramount chief’s turtle fishermen.
Customary requests for sea turtle from the paramount chiefs to their turtle fishermen followed a traditional communication channel between several fishing clans, and when the turtle fishermen agree to the task, they organize a special kava ceremony for accepting the delegated task. The capture of sea turtles by fishermen would be reciprocated by chiefs with tabuaFootnote 6 (a whale’s tooth) and food offerings of yams, taro and pigs (Tippett 1968; Erasaari 2013). Respect for taboos and beliefs associated with it, as well as the restricted access options in pre-modern times limited unauthorized consumption of this chiefly resource, locally protecting sea turtles from overexploitation for centuries. Some beliefs include children being born with disabilities if their mothers consumed turtle meat during pregnancy, or clans getting sick or dying if they consume turtle meat without permission (A. Mataitini, pers. comm. to SK; M.M. Lomaloma, pers. comm. to JV). In those times, elaborate rituals were employed before and after sea turtle captures (Toganivalu and Hunter 1913). Consumption of sea turtles was restricted to chiefs (and sometimes warriors) although, later, the chiefs used sea turtles as tributes to the missionaries and, in the 1830s, Christian iTaukei were allowed to consume sea turtles during a church construction or the opening of a church (Williams 1898). Customarily, sea turtles were used as head of tributeFootnote 7 during ceremonies such as a chief’s birth, wedding or death (Deane 1910; Thompson 1938).
Sea turtles are totem fishFootnote 8 for the people of Nacamaki in Koro and Kadavu, some clans in Taveuni, Galoa in Bua and some clans in Serua, Tuvuca in Lau, Malolo and Malake (M. Tuiono and T. Tikoibua, pers. comm. to SK) (Map S1), and their consumption within these communities is strictly forbidden. Sea turtles in Fiji are still exclusively harvested only by men (Veitayaki 1994; Kitolelei et al. unpublished data). Traditional knowledge of iTaukei fishermen includes the nesting and fishing seasons of sea turtles, both of which are incorporated into traditional fishing calendars (Kitolelei et al. 2021). For example, iTaukei fishermen know that sea turtles nest during the Vula i KatakataFootnote 9 (summer months, from November to March) (J. Bogidrau, pers. comm. to SK). Traditional taxonomic classification demonstrates the cultural prominence of sea turtles in Fiji as the ethno-speciesFootnote 10 are named by fishermen according to turtle’s life stage, color, and sex (Table 1). The great ecological and cultural significance of sea turtles is also reflected in Fijian school children’s drawing of the sea, where they are prominently present (Fache et al. 2022).
The sacredness of sea turtles started to diminish in the 1840s with the beginning of the tortoiseshell trade in Fiji, when sea turtles became part of the cash economy (Williams 1898; Veitayaki 1994). The iTaukei were encouraged to preserve turtle shells, and when the sandalwood and sea cucumber industries failed in 1865, the tortoiseshell trade began with US traders (Williams 1898). The custom of capturing sea turtles only upon a chief’s request fell into disuse, substituted by a widespread exploitation to cater for the tortoiseshell demand and the subsistence or commercial use of meat and eggs (Tippett 1968; Guinea 1993). Colonial influence further changed iTaukei customs (Toganivalu and Hunter 1913; Muehlig-Hofmann 2008), and custom-based norms and rules which limited the exploitation of sea turtles died out and, for about a century, a widespread unhindered sea turtle harvest in Fiji occurred (Guinea 1993). To limit the exploitation and its consequences, the (not yet independent) Fijian Government introduced a regulation of sea turtle harvest in the Fisheries Act in 1941. More recently, a legal prohibition of sea turtle harvest was put in place in 1995, followed by three moratoria,Footnote 11 which collectively prohibited sea turtle molesting, taking or killing as well as harvest of sea turtle eggs from 1997 to 2018. These moratoria acknowledged the customary rights of the iTaukei and reserved them the option to apply for a special “exemption for traditional use” permit from the Ministry of Fisheries, although an application does not necessarily grant a permit. Today, sea turtle protection in Fiji falls under Regulation 5 of the Offshore Fisheries Management Regulation 2014 (OFMR) and the Endangered and Protected Species Act 2002 (a legislation that implements CITES in Fiji). The Fisheries Act and other laws governing sea turtle harvest and use do not integrate the unwritten iTaukei customs which relate to sea turtles.
This study investigates how two Fijian communities of traditional turtle hunters cope with parallel systems (written law policies and unwritten customary rules), and explores the integration of the traditional knowledge with conservation and management of the sea turtles.
Materials and methods
Study sites
Geographically, the study sites (Fig. 1) include USP Laucala Campus in Fiji’s capital city of Suva, and two rural coastal villages with traditional fishermen: Qoma village, where the unwritten customary rules are cited to still catch sea turtles (Kitolelei et al. unpublished data), and Denimanu village, where protection of sea turtles has led to strict adherence to the written national legislation on sea turtle conservation and to an adaptation (at least, temporarily) of the unwritten customary rules.
Qoma village is located on the northeastern coast of Viti Levu and its population is spread between Qoma Levu and Nabulebulewa islands. Qoma shares its customary fishing area (iqoliqoli) with neighboring villages of the same district (tikina). No sea turtle nesting activity is reported from this site (Prakash et al. 2020). The area is known for its green, hawksbill and loggerhead sea turtles (Veitayaki 1994). Its gonedau fish for the Paramount Chief (Turaga na Ratu) of Ucunivanua in Verata.
Denimanu village is on Yadua Island, a hawksbill turtle nesting site (Prakash et al. 2020) located west of Vanua Levu. Its iqoliqoli hosts green and hawksbill turtles foraging grounds (Piovano et al. 2019; Papale et al. 2020), as well as loggerhead sea turtles (P. Qarau pers. comm. to MT). Denimanu fishermen, the gonedau of Bua, are customarily obliged to catch sea turtles for the chief of Bua (Tui Bua). However, they are also part of the Dau ni Vonu (DnV, ‘guardians of the turtles’) network, which was set up in 2010 by the World Wildlife Fund for Nature (WWF) with the aim of increasing the number of sea turtles before resuming hunting. Denimanu village’s commitment to manage and conserve sea turtles is still on-going. Whenever possible, the villagers actively participate in the USP’s sea turtle research project, as well as in non-governmental organizations (NGOs) conservation projects.
Data collection and analysis
Data for this study was collected by combining six methods (Table 2). Briefly, (1) In-depth interviews with elder fishermen were conducted in Qoma and Denimanu in the summer of 2020. Elders were chosen because the interviews focused on gaining insights on the temporal changes in sea turtle fishing since the 1950s. (2) Open-ended questionnaires, which were given to Denimanu sea turtle fishermen in February and November 2015, with the aim of reviewing sea turtle fishing habits in over a 30-year period. (3) Informal conversation (talanoa) sessions with iTaukei staff and students (both men and women) at the University of the South Pacific (USP) who were willing to participate after the research was explained to them. Talanoa were conducted to gauge the use and value of sea turtles during traditional ceremonies. Participants were chosen according to their availability at the time of the talanoa (4) A two-question online survey, done via SurveyMonkeyFootnote 12 to ask the public about the last time they witnessed a sea turtle as the head of tribute, and if that ceremony was associated with a hereditary chief. A link to the survey was shared via social media (Facebook and Twitter). The survey was opened from 19 to 26 October 2021. The questions were asked to gauge how the sea turtle value as head of tribute in chiefly ceremonies changed. (5) Semi-structured interviews, which were conducted in Qoma in 2017 and 2018 with the aim of gaining any change in the perceptions of sea turtle hunting. (6) In-depth questionnaire to focal groups was administered to two male groups, two female groups and one youth group to collect traditional knowledge and fishing background of sea turtle harvest in Qoma and Denimanu. Although women were not involved in sea turtle hunting, they were included in the survey because they actively took part in food preparation, particularly in the cooking of sea turtle meat for feasts.
A qualitative analysis was carried out on the answers given by the 229 participants (51 in Qoma and 75 in Denimanu; Table 2) whose age ranged from 18 to 85-year-old.
Results
A summary of the results is given in Table 3 and expanded in this section. The results are presented by subject and aim to compare the two villages of Qoma and Denimanu.
Target species and fishing methods
Hawksbill and green turtles were targeted by the respondents in both Qoma and Denimanu. The fishermen of Qoma primarily targeted green turtles. In the past, sea turtle eggs were left untouched because nests were located on inaccessible shores and sea turtles were considered sacred. In order to harvest sea turtles, fishermen in Qoma had to seek permission from their chief and sub-clan (tokatoka) by formally presenting yaqona,Footnote 13 and had to follow hunting taboos such as: (i) fishermen must not make unnecessary noise during the duration of the sea turtle fishing, (ii) abstaining from having intimate relations with their wives or women, from the time the sea turtle hunting is decided to the end of the sea turtle hunt, (iii) stealing and infidelity forbidden, (iv) when out at sea, turtle hunters are not allowed to eat products from land until they return from their trip, and (v) any money or gifts received in exchange for the sea turtle harvested is shared equally amongst members of the household including visitors present at the time of the exchange. To fulfil customary and religious obligations, each of the seven tokatoka in Qoma has to contribute one sea turtle at Christmas, Easter and wedding celebrations, and three per tokatoka for an annual church feast. This fulfillment would be done irrespective of obtaining a permit from the Ministry of Fisheries.
In Denimanu, prior to the year 2000, the fishermen altogether would annually collect an estimated 700 eggs of hawksbill turtle, for subsistence only. With an average of 121 eggs per nest (Prakash et al. 2020), this roughly equates with six nests. Fishermen harvested whole clutches. During the nesting season, customary bans were placed on the harvest of nesting females, therefore, eggs were targeted. The practice of egg collection disappeared entirely by the year 2015 (Table 4), and today nests are located and estimated hatched eggs are counted by the DnV in collaboration with NGOs that contribute data for sea turtle population assessments. Green turtles were targeted prior to 2000 for their meat and were sought after both as chiefly tributes (magiti ni kakana vakaturaga) and for subsistence use, because the villagers “preferred the taste of green turtle’s meat over the hawksbill turtle’s and because "it had more meat than fish”. According to the respondents, the Turaga ni Vanua decision to protect sea turtles to increase their numbers in the village waters has led to the village participation at the Dau ni Vonu network and to the village strict adherence to the sea turtle national legislation. As a result of this effort, an 80% reduction in green turtle captures was achieved. From 2000 to 2009 sea turtles were only captured as tributes for a few traditional chiefly ceremonies and weddings. In 2009, sea turtle harvest was declared taboo by the Turaga ni Yavusa. Requests for exceptions could be presented to the chief and, upon the chief’s approval, the customarily authorized fishermen must obtain a permit from the Ministry of Fisheries before the harvest. However, whenever possible, customary tributes of sea turtles are now substituted by the presentation of a live pig or cow as chiefs adhere to the turtle legislation and capturing sea turtles is now harder due to overfishing.
Sea turtle harvest involves two fishing methods and several techniques. In Qoma, fishermen use six net fishing techniques and two spear fishing techniques. In Denimanu, fishermen use one spear fishing technique, one net fishing technique and two specialized target species methods (Table 4). The turtle fishing methods used by fishermen were influenced by the tide, diurnal cycle, fishing location and the purpose of fishing (Table S1).
Temporal changes to customary values of sea turtles
According to an elder in Ucunivanua, an ancient communication channel existed between the paramount chief in Ucunivanua, Mataqali (clan) Saraviti in Naloto village, and the Qoma sea turtle fishermen. This channel is no longer used as the paramount chief in Ucunivanua complies with the sea turtle legislation. Older fishermen who were interviewed in Qoma and Ucunivanua detailed the sacredness of sea turtles as they recollected stories from their grandparents and described how sea turtles were heads of tributes for a hereditary chief’s funeral or wedding and captured only upon request of the paramount chief of Ucunivanua. Such sea turtle capture by fishermen in Qoma stopped in the 1950s, and today a majority of the sea turtles harvested in Qoma are no longer restricted to events for hereditary chiefs. Sea turtle presentation and consumption are for weddings, fundraising events or house construction involving the whole community. Strict customary norms and rules and recent low catch rates (Table S2) made sea turtle fishing nowadays less attractive to Qoma’s fishermen who, nevertheless, are now fishing for sea turtles for both economic and subsistence uses.
In Denimanu, sea turtles were formerly hunted for major communal events, such as weddings or a chief’s funeral, and presented as tribute for the Tui Bua. Prior to the 1960s, turtle hunters captured sea turtles during their nesting period. When a fisherman spotted a sea turtle while out on a fishing trip, that fisherman returned to the village, informed the other fishermen and a turtle hunt was organized by selected fishermen from the gonedau clan. Exploitation of sea turtles in Denimanu spiked, leading to a reduction in sea turtle population between the late 1960s and 1995, and this decrease is attributed to the introduction of fiberglass boats, nest destruction when collecting eggs, climate change and the deterioration of customary taboos on sea turtle captures. In 1995, due to the annual national ban on sea turtle capture, Denimanu villagers slowly began to wean themselves off the consumption of sea turtle meat. A ban imposed by the chief in Denimanu and a community-based initiative to protect the sea turtles made response to the sea turtle conservation efforts easier for the fishermen in this site.
Information collected through talanoa sessions and online survey span over 41 years (1980–2021) show that after the 1995 annual ban on sea turtle harvest and in between moratoria (2001 and 2008), sea turtle harvest was dominated by activities related to a hereditary chief. However, during periods where the moratoria were active, the majority of the sea turtles harvested were not associated with hereditary chiefs (Fig. 2).
Response to legislations, customary law, and third-party interference
Interviewees in Qoma and Denimanu were all aware of the three moratoria protecting sea turtles (Table S2). In Qoma, sea turtle harvest only occurred when approval is given from the chief and sub-clan, with or without sea turtle harvest permits. However, the harvest is approved only if the purpose is stated and their sub-clans agree on sharing the benefits equally in the village. The leaders of the sub-clans ensure that the sea turtles are harvested and used for the purpose initially stated when permission was granted. It has been noted that the requirement of seeking permission in the national sea turtle legislations is substituted by the customary rules which community members adhere to and are monitored within communities.
In Qoma, legal and illegal sea turtle fishing occur together, with permission from their community chief. This choice is based on their belief that enough sea turtles will present themselves for capture only if the fisherman urgently needs them and that transparency is used when sharing the monetary benefits of the catch. Furthermore, turtle sales have become lucrative for Qoma fishermen and their primary income source or subsistence item, and this at times has caused conflicts between the fisherman and community members who adhere to the legislation.
In Denimanu, 40% of the fishermen agreed that the 26 years of sea turtle protection (1995–2021) resulted in an increase in the number of nests, of nesting females and of juvenile sea turtles in their fishing grounds. While sea turtle harvest was monitored by the DnV and the chief in Denimanu, anyone who needed to harvest a sea turtle required a permit from the Ministry of Fisheries prior to the chief’s consent. During the annual ban on sea turtle harvest in 1995, there were no sea turtle captures, and during the first Moratorium, sea turtle harvest was limited to chiefly functions. Most of the few sea turtles harvested in Denimanu since 2000 have been used communally and not for individual subsistence consumption like it was prior to 2000.
Despite the contrasting behavior between these two villages, the last eighty years (1941–2021) have witnessed major reductions in sea turtle harvest in both Qoma and Denimanu (Table 5) when compared to anecdotes from older fishermen. Apart from the government and the community, third parties which are not linked to communities or the government such as non-governmental organizations (NGOs) and academic institutions have played a significant role. In Qoma, interviewees have learnt about the ecological importance of sea turtles from NGOs/academic institutions and, in turn, the villagers have educated them on the cultural value of sea turtles to the people of Qoma. However, the new knowledge did not change the fishermen’s behavior.
In Denimanu, SPREP and WWF’s sea turtle conservation initiative successfully converted sea turtle hunters to conservators, based on the idea to reach a population that can be sustainably harvested. Their presence in Denimanu has influenced a 79% reduction of hawksbill turtle harvest and 88% reduction in green turtle harvest between the year 2000 and 2015. Following this, extensive work has been undertaken by USP. Denimanu as a community incorporated an “adaptive management” strategy in their sea turtle management, based on the combination of local knowledge and skills as turtle hunters with the scientific information provided to them to manage the foraging and nesting areas of sea turtles around Yadua Island.
Finally, in both Qoma and Denimanu, interviewees reported that Christianity influenced their decision to harvest sea turtle. This means that their faith influenced some beliefs associated with sea turtle consumption such as punishment for secretly eating sea turtle meat without a chief’s permission.
Generally, the responses to all the data collection methods were similar, as they all mentioned the importance of sea turtles to the iTaukei culture. They also mentioned the scarcity of sea turtles and how the sea turtle legislations are known to them.
Discussion
There is a growing literature exploring the conflicting situations that can arise when (written) law or policies influenced by Western knowledge are in contrast with (unwritten) traditional indigenous customary rules. Excessive harvesting of the living resources has led to a decline of several species by the mid-twentieth century, after which ‘a period of prohibition, control, and regulation of wildlife use that produced positive results in a few cases and places but failed terribly in the majority followed’ (Larriera 2022, p. 2). Worldwide, legal prohibition and penalties fixed by written policies were effective only where there was a high enforcement capacity, otherwise illegal harvesting would occur (Ingram et al. 2022). In the case of sea turtles, commitments to conservation started by adhering to international policies (e.g., CITES), upon recognizing a local population decline. Among the successful instances are systems allowing for monitored but legal commercial harvest; for example, a community cooperative in Costa Rica run a managed olive ridley egg harvest program for over 35 years (Campbell et al. 2007). Some countries adopted a different approach; for example, Aboriginal and Torres Strait Islander communities are legally entitled to harvest sea turtles for personal, domestic, and non-commercial use.
In recent times, a “compassionate philosophy” against animal use has developed in the urban centers of the Western countries (Griffin et al. 2020). On the contrary, Indigenous people in tropical Pacific and worldwide are increasingly claiming their traditional rights to harvest local resources (Beltran and Phillips 2000). Community-based management involving both people with and without decisional power, and integrating scientific knowledge (particularly of population dynamics) with traditional knowledge, proved to be effective in resource management and restoration (see for example the Locally Managed Marine Area NetworkFootnote 14). Conservation through sustainable use, tailored to local situations and implemented via adaptive management, can be the way forward to ensure a sustainable use of the marine resources that is also respectful of local culture and traditions (Webb 2002). For example, in the case of crocodilians, there are several instances across the Southern Hemisphere where modern management of crocodiles was successfully carried out by integrating local traditional values (Brackhane et al. 2019). However, sea turtles are listed in Appendix S1 of CITES, consequently the signatory Countries are not allowed the commercial use of this traditional resource. In such a case, we suggest considering the inclusion of traditional and/or subsistence use. For example, based on our findings of the turtles’ customary importance in Fiji, we suggest a quota system of ten sea turtles (dua na biFootnote 15) annually for each of the seven paramount chiefs.Footnote 16 Based on the current (although illegal and unreported) national annual harvest, we consider that reducing the captures to seventy juvenile specimens per year is a step towards the conservation goals. If the sea turtles that are captured are not used, they can be kept in tidal pools or traditional tidal pens and carried over to the following year. This quota system can be monitored through a collaboration between fishermen, fish wardens, fisheries officers and NGOs. This system could work in Fiji because it accounts for traditional obligations of fishermen to their paramount chiefs and for communal feasts. It also gives a chance for slow integration of conservation and monitoring efforts into the rural communities, and for recruiting more DnV members across Fiji’s customary fishing communities.
Customary law which regulates the use of resources at the local level is governed by customary authority and is vital in sustaining resources (Veitayaki 2000; Clarke and Jupiter 2010). Successful customary management practices depend on the strong leadership, monitoring and enforcement of regulations and social networks (Gutiérrez et al. 2011). When legitimate leaders inspire changes which are guided by the collective interests of the community, their decision-making enhances the community’s compliance to regulation changes and a community’s resilience as they go through governance changes (Olsson et al. 2004). When a community acknowledges a leader, they impact the strength of their leader’s influence and the obedience of the community (Sutton and Rudd 2016); which impacts on the success of conservation outcomes (Ison et al. 2021). For example, in Denimanu village, turtle fishermen comply to the turtle legislation because of the ban placed on sea turtle harvest by the chief and the community-based initiative to protect sea turtles. Community-based management initiatives which seek collaboration and adaptive management can work where communities are actively involved in resource management which are based on their communal management goals. Examples from the Pacific Islands include the collaborative and bottom-up structure set up in Palau for sea turtle management (Risien and Tilt 2008), community-based management of leatherback turtles in Solomon Islands (Jino et al. 2018) and the community-based management of nearshore fishers in Vanuatu (Léopold et al. 2013).
Reports of failed community-based management are often linked to their lack of association with higher level governance and related enforcement, resulting in outsiders entering a managed territory and exploiting the resources therein; such as the case of the Gulf of California, Mexico, where a locally created and enforced network of marine protected areas led to an increase in fishing resources’ abundance which, in turn, attracted poachers who were not bound by the local harvesting rules, resulting in overexploiting and rapid declines of the resources (Cudney-Bueno and Basurto 2009). Furthermore, marine resource use, management and conservation issues are complex (Ison et al. 2021) because of their multi-dimensioned nature, where the community, government, NGOs and academic institutions collaboration play key roles in strengthening conservation.
Organizations outside of the community and government often enable marine conservation by creating opportunities and tools which motivate conservation such as advocating concern for marine issues, providing scientific expertise, implementing conservation plans, enforcing management strategies and enabling the facilitation and capacity building in communities (Sutton and Rudd 2016). A collaborative environment which brings together public policy decision-making and positively engages people in public and private agencies, government and the civic society, creates an attitude of ethical engagement, communal motivation and the ability for collective achievements (Emerson et al. 2012). This is shown in Canada where two environmental NGOs work alongside government and communities by transmitting scientific data and information from researchers to decision makers therefore, advancing policy and practice (Cadman et al. 2020).
Conservation efforts or compliance to legislations fails in communities if the community and the leader do not support the initiative (Adams and MacShane 1996). Furthermore, Indigenous societies believe that culture defines nature, its value, as well as its conservation (Campbell 2002). As shown in this study, Qoma fishermen and their chief place the cultural value of sea turtles ahead of conservation efforts and legislation compliance. In addition, some Qoma fishermen believe the sea turtles are a God-given limitless resource (Kitolelei et al. unpublished data). An intersection between culture and conservation provides complexities in effectively regulating the conservation of sea turtles. A similar case is shown in the Caribbean Coast of Nicaragua, where conservation efforts by Wildlife Conservation Society aligned to the global sea turtle conservation is rendered ineffective because local communities traditionally harvest and consume green sea turtles (Conte 2011). In Denimanu, giving up the traditional right to harvest sea turtles is a choice the fishermen and their chief are willing to temporarily accept to ensure that their future generations will enjoy sea turtle sightings and harvesting. Realization that sea turtles are a resource with limits encourages Denimanu fishermen to protect sea turtles from overexploitation and to act to help the populations’ recovery. The genuine request to protect sea turtles from local communities ensure that the legislation adherence is enforced and sea turtle populations are monitored, as it is occurring in Denimanu.
Integrating unwritten rules into formal governance of marine resources contributes to management which is better equipped for future change (Pellowe and Leslie 2020) and finds common ground between everyone working in conservation. The essential foundation for collaborative governance of marine resource conservation is creating trust (Rapp 2020) which is built on values and integrity of individuals in achieving the same goal. For example, based on our findings, multiple efforts carried out by NGOs and USP can lead to observance of the national sea turtle policy by the local fishermen and the creation of a trust relationship between the sea turtle biologists and managers. Furthermore, for Denimanu village, it has led to continued efforts in protecting sea turtle nursery and feeding grounds at Yadua Island. Denimanu turtle hunters, who are in constant contact with sea turtles, are the local experts who possess key information on the health and status of sea turtle feeding habitats, nesting sites and habits. Acknowledging that their sea turtle populations have decreased over the years demonstrates a deep understanding, which led them to act to ensure that their future generations are able to have the same opportunities to catch sea turtles at their foraging grounds and to view sea turtles nesting on their island shores. We suggest the documentation of traditional knowledge and customary rules linked to sea turtle conservation, and their integration with scientific findings and research so that decision makers will make better informed recommendations.
However, in Qoma fishermen ignored marine conservation awareness efforts brought to their community by Government and NGOs and, instead, provided their own insights into the value of sea turtles to them as a gonedau clan for the paramount chief in Ucunivanua. In a customary setting, obligations are shared between the inland-based clans and those along the coast, where the presentation of tributes to a paramount chief obliges the inland-based clans to provide land-based resources and the coast-based clans to provide marine resources. The legally mandatory absence of sea turtles as a head of their tribute forces the gonedau clans to choose an alternative meat tribute, such as pigs or cattle, removing the customary live marine resource presentation delegated to the fisher clans. Accepting the legislation would make redundant their role as gonedau, and would be disrespectful to their paramount chief. Qoma turtle fishing is self-regulated because fishermen believe a sea turtle would allow itself to be captured when the fishermen need them – irrespective of it being for customary or economic purpose. We recommend a review of the existing policies to account for the traditional cultural role that iTaukei place on sea turtles as a way to convince ‘reticent’ villages, and thus to improve sea turtles management and conservation in the country.
Finally, our findings show the influential roles paramount chiefs and village chiefs still have in mobilizing the fishermen to monitor the sea turtles and spread awareness on the proper management of sea turtles in rural areas. A respected traditional leadership is a key factor in the success of locally managing marine and aquatic resources (Muehlig-Hofmann 2008). In both Qoma and Denimanu, the approval of the currently installed chief to harvest sea turtles carries more weight for turtle hunters compared to the permit given by the Ministry of Fisheries. Moreover, whenever a paramount chief requires sea turtles as a tribute, their gonedau will be informed through a traditional messenger, and they will carry out their duties as turtle hunters and present their catch to the paramount chief. This relationship between the gonedau and the chiefs is not dictatorial but the iTaukei custom of veivakamenemenei (act of showing loyalty to the chief), which is still practiced in many iTaukei communities today. We suggest that paramount chiefs, their gonedau and the village chiefs be offered the opportunity to witness the results of effective sea turtle protection programs, like the one on Yadua Island in Bua.
Conclusion
Formal policies which govern marine resource use are important in shaping conservation. The correct translation and interpretation of these policies to resource users is vital for the compliance, particularly when dealing with culturally important resources such as sea turtles. Collaborative efforts between all stakeholders needs to create trust which is based on collective needs in conserving a resource. In the case of sea turtles, acknowledgement of roles which fishermen play and the unwritten rules which govern their resource use, can create a better policy for sea turtle governance if the informal rules are integrated into formal rules. This can be facilitated by third parties who bridge gaps and transmit the scientific and traditional knowledge to policy makers who use the knowledge as a foundation for creating a more holistic policy; which incorporates the needs of the community, the environment and creates a stronger step to sea turtle conservation.
Notes
Management unit: a genetic and demographic independent nesting population managed as a distinct unit (Moritz 1994).
Epibiont: an organism that lives on the surface of another organism and by definition is harmless to its host (Lescinsky 2001).
Chiefs (Turaga ni Vanua) are hereditary leaders in iTaukei villages chosen from the chiefly landowning units (mataqali) by the chief-makers (sauturaga). Chiefs were responsible for day-to-day village governance and were responsible for the final decision-making during communal meetings. They also regulate the use of resources within customary iTaukei boundaries. (See Appendix S2 in the Supplementary Materials).
A tabua is the most valuable cultural item in the iTaukei society, referred to as kamunaga (‘wealth’). Tabua was a rare commodity in Fiji prior to the late 1700s, when the Tongans brought whale’s teeth and exchanged them for knowledge and skills on how to construct traditional war canoes (Gatty 2009).
The head of tribute refers to the most valued resource presented with customary gifts during iTaukei ceremonies performed for weddings, funerals, or other village setting customary gathering.
Sea turtles are considered a totem fish because of their underwater marine life. In some parts of Fiji, they are referred to as ‘ika bula’ (‘live fish’) because they are marine animals (‘fish’) which remain alive when out of water.
Vula I katakata refers to the iTaukei calendar period which includes the summer months of November through to March. This period is signified by the ripening of native fruit trees, spawning of land crabs (Cardisoma carniflex), sea turtle nesting period and aggregation of baitfish which attract large finfish. This is also the period in which iTaukei fishers carry out group fishing (yavirau).
Ethno-species: vernacular names used in folk classification that can match, under-differentiate or over-differentiate as compared to scientific species (Berlin 1992).
1997–2000 (3-year moratorium), 2002–2007 (5-year moratorium), and 2009–2018 (10-year moratorium).
Information on how respondents are recruited to SurveyMonkey is available here: www.surveymonkey.com/mp/audience.
Root of the kava plant (Piper methysticum) used as a ceremonial or social beverage in Fiji.
Dua na bi is equivalent to ten sea turtles in the iTaukei traditional counting system. Bi refers to the standing cages in which sea turtles are kept after being captured. Ten adult sea turtles can fit in one Bi.
