Abstract

The difference in fishermen's catches each year tends to fluctuate at different fishing locations; this is due to the still low efficiency and productivity of fishing efforts. The purpose of the study was to evaluate the performance of tuna handline businesses operated in fish aggregating device areas at fishing grounds in FMAs 713 and 714. The results show that in the period of 2020-2023, the development of catch rates each year fluctuated, while the average value of catch rates for each vessel based on the highest season occurred in the East Season and the lowest in the Transition Season I. Likewise, the average catch rate based on the time of the month of capture is highest in June, July, and November. The results of the analysis of production factors that influence the catch are the time of the month of fishing, fuel use, ice use, and number of crew members, while the factors of trip length, ship GT, and engine capacity do not have a direct influence. The information from this evaluation is very much needed by fishermen and stakeholders to optimise the performance of tuna handlines in fish-aggregating device areas.

Abstract

Rumpon, as a fish-aggregating device, has long been used by tuna handline fishermen in Bone Bay, South Sulawesi Province, Indonesia. Information on the characteristics of tuna handline fishing in the area is very limited and is very much needed as study material for tuna fishing strategies and fisheries policies. This research aims to understand the results of handline catches and sustainable solutions for tuna fisheries in rumpon areas. The data used is the result of observations using 19 ships based at PPI Lonrae and data collection for 5 years (2018-2022). The results show that the composition of the main catch is dominated by yellowfin tuna (Thunnus albacares), bigeye tuna (Thunnus obesus), and skipjack tuna (Katsuwonus pelamis). In general, the size of fish that are not suitable for catching for the yellowfin tuna, bigeye tuna, and skipjack tuna, consecutively, is 54.0%, 45.1%, and 31.9%. This finding further clarifies that the percentage of tuna and skipjack tuna that are not suitable for catching is still very large. Continuous and large-scale fishing of juvenile tuna could cause fish resources to continue to decline in the future. Technically, what fishermen need to understand is, in addition to the strategy of lowering fishing gear deeper, the time of fishing and the type of bait used.
