REARING TECHNIQUE OF CRAFT SEED (Portunus pelgicus linn) AT THE BRACKISHWATER FISHERIES DEVELOPMENT CENTER (BBPBAP) JEPARA

Abstract

Blue crab is one of the fishery commodities that should be preserved because of the increasing market demand so that the selling price of crabs increases every year. Blue crab seed maintenance techniques are very necessary in the cultivation of blue crab seeds to support the continuous availability of seeds and be able to meet market demand. The main parameters observed in this study were growth monitoring and survival rate. Growth monitoring started from the zoea stage to the carblet, which at the blue crab carblet stage was 0.5-1 cm in size. The survival rate value is 3.33%. The water quality value obtained at the time of the study were pH 7.43-7.9, temperature 20,9-33,90C, DO 4,39-6,6 mg/l and salinity 15-30 ppt.
