Abstract

This study aims to determine the performance of small-scale grouper fisheries in Saleh Bay using a spatial bioeconomic approach. The optimal fishing trip allocation and economic rent based on the fishing grounds and its season were estimated using this approach. The results showed from the seven main fishing grounds (DPI) in Saleh Bay, the highest optimal trip need to be allocated to DPI-7 with approximately 2833 trips per year, followed by DPI-5 (2107), DPI-1 (1158), DPI -4 (1064), DPI-6 (970), DPI-2 (940) and DPI-3 (524). The intensity of fishing trip responded to the quasi-profit. The grouper catches produced quasi-profits of IDR 1.4 billion per year. The maximum and minimum annual profits of IDR 428 million and IDR 55 million were achieved in DPI-7 and DPI-3, respectively. This trip allocation complements the existing restriction management instrument, related to the control of input, area and season closure options. This strategy choice eases the fisheries managers to focus on spatial and temporal control efforts with high resolution.

Abstract

The most attention issue of sustainable fisheries management is related to the availability of catch and fishing efforts data with the spatio-temporal distribution. The monitoring data plays important to evaluate the fish stock status and fishery dynamic in the waters. As dependent-fishery data, logbook data is a reliable data source for estimating the utilization rate of fish resources and designing effective regulation tools in fisheries management areas. This study aims to analyze catch composition, spatial and temporal distribution, and productivity (catch per unit effort) of small-pelagic purse seine fisheries in the Java Sea using fishing logbook data. The result shows the highest It was found that the catch composition of small pelagic purse seines was dominated by longtail tuna/kawa-kawa, scad (Decapterus spp.), and sardinella fimbriata with the highest catches annually occurring in September 2021, March 2020, and November 2019. However, the highest productivity was achieved in September 2021, May 2020 and June 2019, namely 1,290 kg/setting/day, 1,700 kg/setting/day, and 1,660 kg/setting/day, respectively. Regarding spatial distribution, the highest productivity was in the northern and central parts of the Java Sea and the southern parts of Kalimantan.
