Evaluation of Fish Resource Status as Raw Materials for Smoked Fish in Promoting Coastal Tourism in Prigi Bay, Trenggalek, Indonesia

Prigi Bay presents a variety of appealing tourism attractions, including pristine sandy beaches, mangrove ecosystems, and turtle conservation efforts, hence providing a substantial chance to draw both domestic and foreign visitors. Tourists typically do not depart without acquiring distinctive gifts. A unique gift from this region is smoked fish, made by traditional methods, yielding a distinctive and delectable flavor. Nonetheless, the substantial demand for smoked fish must be reconciled with the appeal of the fish supplies within its waterways. This study aimed to evaluate the profitability and financial viability of the smoked fish processing industry, as well as to assess the availability of fish resources as raw materials for this process in Prigi Bay, Trenggalek. Prigi Bay is a region with high fish production and attractive coastal tourism, offering opportunities to develop local souvenirs, such as smoked fish. The profitability of the fish processing enterprise yields R/C, BEP, profit, and profitability that align with established profitability criteria. The viability of the smoked fish processing enterprise yields a favorable NPV, a Net Benefit-Cost ratio over 1, an IRR surpassing the 12% interest rate, and an expedited Payback Period. The investigation of the exploitation status indicated that five of the six primary commodities— blue mackerel, skipjack, squid, tuna, and rainbow runner— are undergoing biological overfishing, with tuna and blue mackerel facing the most pressure. The majority of species are in a state of full or moderate exploitation, whereas yellowfin tuna is nearing full exploitation but has not yet reached overfished status. A marketing strategy centered on high-value commodities, collaborative stakeholder engagement, and stringent fisheries management laws, including catch quotas and seasonal fishing limitations, to guarantee ecological and economic sustainability. These findings confirm the financial viability of a fish smoking enterprise in Prigi Bay by employing a fish stock-based adaptive quota model, which adjusts raw material allocation according to exploitation status, prioritizing fish resources that remain unsustainably harvested
