Abstract

To support improving fisheries management on tuna fisheries in Indonesia FMA (I-FMA) 713-717, an Indonesia - Australia research collaboration conducted a study during November 2013 – December 2015 at two key tuna fishing bases including Kendari (Southeast Sulawesi) and Sorong (West Papua). This study involved an enumeration program with skipper interviews, direct observations and biological sampling. The study showed that all fish aggregating devices (FADs) in Indonesian waters are anchored fish aggregating devices (aFADs). Three main fisheries associated with aFADs include purse-seine (PS), pole and line (PL) and hand-line (HL). The PL fishery based in Sorong had the highest FAD-success rate-FSR (84.9 %) compared to other fisheries including PL and HL based in Kendari. The average catch rates of PL and PS boats based in Sorong 2013-2015 were 10,352 and 33,854 kg/trip/boat respectively. The average catch rates of PL and HL boats based in Kendari were 2,819 and 1,135 kg/trip/boat respectively. Apart from the catch of HL based in Kendari, the largest proportion of the catch was juvenile yellowfin tuna (j-YFT) and juvenile bigeye tuna (j-BET). The proportion of sharks and billfish as by-catch species, in the landings of HL and PL boats based in Kendari and Sorong was extremely low.

Abstract

Tuna and skipjack are large pelagic fish that have high economic value and have a very wide export market. The need for and the high market demand for tuna and skipjack causes the intensity of catching this fish to increase. To ensure that the potential of these fish resources remains sustainable, it is necessary to properly manage fisheries.The purpose of this study was to examine several aspects of biology, aspects of capture fisheries, aspects of utilization and management of yellow fin tuna and skipjack tuna. Data collection for yellowfin tuna was focused on one location, namely PPS Bungus, while data collection for skipjack tuna was focused on 4 location points, namely PPS Bungus, PPP Carocok Terusan, PPI Kambang and PPI Tiku. Productivity and cultivation levels of yellowfin tuna in West Sumatra have tended to decline in the past 4 years (2017-2020). Skipjack tuna in the West Sumatra region caught by boat charters was indicated to be overfishing, while skipjack tuna caught by troll showed the fish caught had not spawned yet. The productivity of skipjack tuna has fluctuated over the past 5 years (2016-2020).
