Small pelagic fisheries in West Indian Ocean Waters of Sumatera

Abstract The small pelagic fisheries in PPS Lampulo make an important contribution to the development of fisheries in Indonesia, especially in Fisheries Management Area (FMA) 572. The small pelagic rank second after large pelagic and need to be managed can be sustainable. As basic information for fisheries management, a study was conducted at PPS Lampulo in 2020 to obtain information small pelagic fisheries related to fishing effort, catch results, fishing ground distribution, abundance index (catch per unit effort), and biological parameters (Lc) from purse seine. The study show that during the period 2006–2020, 10 species of small pelagic were caught using purse seine, dominated by Decapterus macarellus 70.7%, Canthidermis maculata 5.1%, Rastrelliger kanagurta 4.3%, Atule mate 3.9%, Elagatis bipinnulata 3.8% Amblygaster sirm 3.4%, Alloteuthis subulata 3.3%, Decapterus macrosoma 2.2%, Sardinella albella 2.1%, and Megalaspis cordyla 1.1%. The length at first capture (Lc) for mackerel scad was 24.3 cm FL, yellowtail scad 7.5 cm FL, and white sardinella 16.6 cm FL. Some small pelagic fish species are caught after reaching adult size (Lc > Lm), this is indicating sustainable small pelagic resources and The average CPUE of purse seine is 1.62 tons/trip.
