Limited information is available on artisanal and subsistence shark fisheries across the Pacific. The aim of this study was to investigate Fiji’s inshore fisheries which catch sharks. In January and February 2013, 253 semi-directive interviews were conducted in 117 villages and at local harbours on Viti Levu, Vanua Levu, Taveuni, Ovalau and a number of islands of the Mamanuca and Yasawa archipelagos. Of the 253 interviewees, 81.4% reported to presently catch sharks, and 17.4% declared that they did not presently catch any sharks. Of the 206 fishers that reported to catch sharks, 18.4% targeted sharks and 81.6% caught sharks as bycatch. When targeted, primary use of sharks was for consumption or for sale. Sharks caught as bycatch were frequently released (69.6%), consumed (64.9%) or shared amongst the community (26.8%). Fishers’ identification based on an identification poster and DNA barcoding revealed that at least 12 species of elasmobranchs, 11 shark and one ray species (Rhynchobatus australiae) were caught. This study, which is the first focused exploration of the shark catch in Fiji’s inshore fisheries, suggests that the country’s artisanal shark fisheries are small but have the potential to develop into larger and possibly more targeted fisheries.

Understanding the population structure of a species and the barriers that disrupt dispersal is important to accurately assess the global conservation status and manage the risk of local extinction. This is especially true for species of commercial importance (Begg et al., 1999) or conservation concern (Moritz, 1994), which are impacted disproportionally by anthropogenic or environmental pressures.

Sharks are an important component of coastal fisheries. Accordingly, the impacts of small-scale shark fisheries are likely significant, but data, including socioeconomic drivers, are often scarce. Fiji features active but largely unregulated and unmonitored artisanal fisheries. Data suggest that the country's small-scale shark fisheries have the potential to become more targeted. This study considers the socioeconomic value of shark fisheries across stakeholder groups. In 2017, semi-structured interviews were conducted with 211 fishers throughout Fiji, out of which 66.8% reported catching sharks of 11 species. Of those who caught sharks, 19.9% stated to release them dead or alive, while 78.7% retained the sharks. Various reasons were cited for shark retention with the most common explanation being to meet dietary needs. Only 19.8% of the participants who retained sharks sold them, yet fishers who gain additional income from the sale of sharks had significantly higher mean maximum catch rates compared to fishers who retained sharks for consumption. Fewer fishers reported selling shark fins compared to a previous comparable survey. This study indicates a decreasing relevance of smallscale coastal shark fisheries for income generation but an increasing utilisation of shark meat as a substitute for traditional food fishes.

Effective species conservation requires the protection of all stages of its life-cycle. The Shark Reef Marine Reserve (SRMR) in Fiji is a marine protected area where large numbers of adult bull sharks (Carcharhinus leucas) congregate due to food provisioning. At the end of a calendar year bull sharks leave the area for reproductive activity, but parturition sites are still unknown. Between February 2014 and January 2015, we interviewed local fishermen and conducted a fishing survey, so as to assess presence and abundance of bull sharks in the Navua River near the SRMR. In total 84% of fishermen reported either seeing or catching sharks up to 8km upriver from the river mouth. They described them as small sharks having a rounded snout and being grey–brown in colour with a white belly, morphological characteristics that match juvenile bull sharks. During the fishing survey, a total of nine juvenile bull sharks were captured, including two that were recaptured after 108 and 92 days at liberty. Our findings confirmed the presence of bull sharks in the Navua River and provide a preliminary characterisation of a potential shark parturition or nursery area from a data-poor region.
