Abstract
The squid commodity, as a commodity that has high economic value, needs special attention in managing the catch. PPN Brondong as one of the contributors to squid commodity production in Lamongan Regency with a trend of increasing squid production every year provides an illustration that the risk of over-exploitation could occur in the future. Efforts to control the capture of captured fisheries commodities as part of preserving existing fish resources and the conditions of Indonesian fishermen who are synonymous with poverty seem to be the opposite or inversely proportional. However, attention to preserving fish resources can actually maintain the sustainability of existing capture fisheries activities. The aim of this research is to analyze the sustainable potential of squid commodities or conditions Maximum Sustainable Yield (MSY), analyzing the level of squid utilization under conditions Maximum Economic Yield (MEY) and arrest Open Access (OA), as well as determining the status of squid utilization at the PPN Brondong in the form of exploitation level, level of fishing effort, and squid stock status. The analytical method used in this research uses a production surplus approach consisting of the Schaefer model, Gulland model, Walter-Hilborn model, and Schnute model; using the Gordon-Schaefer bioeconomic analysis method; as well as the fish stock status classification method modified by Fauziyah., et al (2019). The types of data used in this research are primary data and secondary data. Primary data was obtained from interviews with fishermen as respondents, documentation, observations, while secondary data was from the PPN Brondong management office, literature studies from books, journals or related sources. The potential for squid in PPN Brondong based on the number of catches from 2014-2023 was highest in 2023 and lowest in 2014. The level of effort to catch squid in PPN Brondong from 2014-2023 was highest in 2017 and lowest in 2023. Estimating the sustainable potential of squid, the production surplus model that is in accordance with the conditions of the squid fishery in Brondong PPN is the Schaefer model with the maximum sustainable yield (CMSY) of 3,997.7045 tons and optimum fishing effort (Eopt) amounting to 5,477 trips. Gordon-Schaefer bioeconomic analysis in MEY conditions showed a catch value of 3,969.3665 tons and a fishing effort of 5,016 trips. In the OA condition, the value of the catch is 1,233.6902 tons and the fishing effort is 10,032 trips. The economic approach obtains an economic rent in the MSY condition of Rp. 133,364,795,995.80 (Rp. 24,348,764.38/trip) and in the MEY condition of Rp. 134,503,161 ,094.49 (Rp. 26,815,736.68/trip). The condition of squid stock status is obtained overfishing stock (2014-2022) until status healthy stock (2023). The results of the classification of squid effort levels obtained overfishing status (2014-2022) to underfishing status (2023). The classification results obtained level exploitation status moderate-exploited (2014-2015), fully-exploited (2016-2022), and over-exploited (2023).
