Peran kajian kemampuan dan tingkah laku renang ikan baung (Hemibagrus sp) untuk teknologi penangkapan ikan dan usaha budidaya

Abstract

Swimming speed and endurance of baung (Hemibagrus sp)(FL = 16.13 ±1.14 cm) observed in swimming channel. Swimming speed has negative correlation to the endurance time. The endurance time was decreased when the swimming speed increased. Sustained swimming speed was less than 2.5 BL/s, corresponded to 40.3 cm/s and burst swimming speed was up to 10.5 BL/s, corresponded to 169.4 cm/s. Prolonged swimming speed was 2.5-10.5 BL/s (40.3-169.4 cm/s). Sustained swimming speed are recommended for fish-farming in aquaculture cage. Burst swimming speed was illustrated swimming speed of fish to escape and avoid the gear in capture process.
