“…However, it still occurs. For example, in North Maluku, Indonesia, fishers fin sharks at sea because locals do not eat the meat and boats have limited storage (Ichsan et al., 2019 ; Jaiteh, Hordyk, et al., 2017 ).…”

“…By contrast, shark flesh price is generally lower in other parts of the world. For example, fishers receive up to US$4 in Brazil, US$3.4 in the US and less than US$1 in Indonesia per kilogram for flesh (Martins et al 2018;Ichsan et al 2019;Ferretti et al 2020), which may lure fishers into targeting sharks for their fins because these can attain considerably higher prices, such as US$22-$104 kg -1 for fins in Indonesia (Ichsan et al 2019). By contrast, there is little economic incentive in the TDGDLF for 'shark fining', i.e.…”

Context Social and economic information is limited for coastal commercial and recreational fisheries, particularly shark fisheries, which are perceived as unsustainable and as targeting sharks for fins. Aims To characterise the social and economic dimensions of one of the world’s few long-standing sustainable shark fisheries. Methods We reviewed historic data and surveyed stakeholders to understand the economic and social dimensions of the shark fishery currently operating in Western Australia. Key results Since the fishery’s historic peak, there has been a substantial reduction in the number of operating vessels and ports due to management intervention. For the vessels that have remained, catches and catch rates increased through time. Fishers sold only flesh and fins, whereas processors also sold cartilage. Revenue mostly originates from the domestic sale of flesh, not fins. This fishery provides additional social and economic returns through the employment of an average of 102 people per annum, the supply of local fresh seafood to communities and the expenditure of most of operational costs in local government areas. In addition, the average annual market value through the supply chain was A$32.6 × 106 (US$20.9 × 106). Conclusions Our study is the first step towards a more comprehensive valuation of the societal contribution of sustainable shark fisheries. Implications This novel information has a range of applications, from developing social and economic objectives in fisheries harvest strategies to empowering government agencies when making decisions on natural resource management.

“…Estimating the economic costs of shark conservation for fishers requires understanding the supply‐side value of conservation‐priority species. However, sharks are typically captured and sold as mixed‐species bundles, with a single price at the ex‐vessel level that does not differentiate by species and their implicit attributes (Fahmi, Sarmintohadi, & Mustika, 2013; Ichsan, Simeon, Muttaqin, Ula, & Booth, 2019). This makes it difficult to tease apart the values of different species within the catch.…”

Understanding wildlife markets is central to effective conservation: it can help managers and policy-makers to predict how interventions might influence supply and demand of wildlife products, and economic welfare of wildlife users; and thus, design interventions which have better outcomes for wildlife and people. Here we apply a revealed preference method of economic valuationhedonic price analysis (HPA)-to understand shark markets and explore the economic costs of shark conservation for small-scale fishers. We focus on a targeted semi-commercial shark fishery in Indonesia-which poses a threat to some shark species, but provides important economic and subsistence value for a coastal community in an impoverished region of Indonesia-and use HPA to estimate market prices and welfare measures for threatened and CITES-listed sharks. This represents a pertinent case study with practical implications because Indonesia is the world's largest shark fishing nation, where management interventions to reduce shark fishing mortality are needed. However, such interventions will create short-term socio-economic trade-offs for fishing communities, which may hamper cooperation and compliance, and raise concerns regarding the fairness and equity of conservation.Our results give significant marginal price estimates for five species of conservation and commercial importance. Dusky sharks (Carcharhinus obscurus) and bottlenose wedgefish (Rhynchobatus australiae) have the highest implicit marginal prices, at US$ 157 and US$ 144, respectively. Our estimates suggest that conservation measures, such as catch limits for endangered and CITESlisted species, could have significant economic opportunity costs (i.e., 3.4-17.6% revenue foregone) for low-income fishers. Innovative policy instruments are required to transform shark markets and fisheries-to effectively reduce threats to endangered species and implement CITES, whilst doing no harm to vulnerable coastal communities. Methods from econometrics can help conservation scientists to better understand wildlife markets, and make management decisions which create better outcomes for wildlife and people.
