【 摘 要 】

Lift net was a Makassar traditional fishing gear that attached into the seabed, used paraffin lamps as fishing devices and used net with mesh size 0.5 cm. Lift net had low selectivity whereas in order to obtain sustainable fisheries, the catches should be mature fish phase (gonad ripe). This study aimed to determine the value of opportunity loss due to the low selectivity in operation of lift net. This research was held in June - July 2018 in Makassar Waters. This study used secondary data of South Sulawesi Fisheries Statistics 2010 - 2016, primary data such length and weight of lift net catches and some literature studies. There were five species caught by lift net such as mullet (Valamugil seheli), shrimp (Penaeus merguiensis), peperek (Leiognathus equulus), sardine (Sardinella gibbosa), and anchovy (Stolephorus commersonii). Based on the results, the percentage of mature fish of lift net catches was 60% of mullet, 20% of shrimp, 39% of peperek, 5% of sardine and 5% of anchovy. The average value of the opportunity loss of lift net operation during 2010-2016 in Makassar waters was Rp. 437,090,000.
