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.

Abstract

Indonesian archipelagic waters, including the Fisheries Management Areas  (FMAs) 713, 714 and 715, have significant potential for tropical tuna fisheries. The government has prepared harvest strategies to optimize the utilization of these tuna species such as skipjack (SKJ), yellowfin tuna (YFT), and bigeye tuna (BET) in these waters. This paper aims to provide an overview of the characteristics of these fisheries in Indonesian archipelagic waters based on a descriptive analysis of fishing logbook and observer program data received by the Ministry of Marine Affairs and Fisheries. The study shows that during the 2019-2021 period the number of purse seine (PS) trips was relatively stable while hand line (HL) and pole and line (PL) tended to increase. In 2021, the catch composition of PS was dominated by SKJ (73%) and YFT (27%). PL caught SKJ 83% and YFT 17%, while HL's catch was significantly comprised of YFT (95%), BET (2%), and SKJ (3%). BET was predominantly distributed in FMAs 714 and 715, whereas the fishing grounds for YFT closely resembled those for SKJ. The results also provided information that the size composition of tuna species varied based on the fishing gears operated. The mean length of each species caught by PS was smaller than other gears, namely SKJ at 36.9 cm, YFT at 40.22 cm, and BET at 52.87 cm. Therefore, immediate management actions are needed to prevent juvenile capture in the area to ensure the sustainability of tropical tuna fisheries.
