Abstract
This study analyzed the catch of the ponyfish (Leiognathus equulus) landed at Muara Kintap Fishing Port in South Kalimantan, Indonesia. Local fishermen used various gear types especially bottom trawls, beach seines, drift gillnets, and encircling gillnets within Indonesia's Fisheries Management Area (FMA) 712. While bottom trawls displayed the highest efficiency, peaking at 65,956kg, representing 98.26% of the annual total catch. Moreover, they also indicated potential overfishing, particularly in 2022. The ponyfish catches were dominated by individuals measuring between 130- 134mm and weighing 35- 39g. Length-weight relationship data revealed an isometric growth pattern (b = 2.98) for the ponyfish, suggesting good overall health (K = 1.68± 0.17). However, CPUE (Catch per Unit Effort) data from 2022 raised concerns. The peak CPUE of 89.13kg/ trip, alongside a substantial total catch of 67,122kg across 753.1 trips, significantly surpassed the catch-maximum sustainable yield (CMSY) of 28,748kg/ trip and the optimal effort (Fopt) of 882 trips/year. This suggests overfishing and a potential decline in the ponyfish stock by 2023, representing a substantial loss of USD 3,934. Monthly catch data for 2022 further supported this, highlighting a fishing season from August to October, peaking in October (16,376kg) and continuing into December. To ensure the sustainability of the ponyfish population and fish processing industry, the fishing port authority should prioritize addressing the impact of overfishing practices, particularly trawling. Furthermore, continuous monitoring efforts are crucial to establish data-driven fisheries management practices.
