Pertumbuhan, Sintasan dan Keragaan Zoea Sampai Megalopa Rajungan (Portunus pelagicus) Melalui Penurunan Salinitas
Abstract: The purpose of this
experiment was to know the influence of lowering salinity to growth, survival
rate and performance zoea-megalopa of blue swimming crab. The experiment was
done in concrete tank of 3,000 liters water provided with aeration system and
initial zoea-1 density of 75 ind/l. Different lowering salinity for larva
rearing were A: salinity for zoea-1 to megalopa stages of 32-34 ppt; B:
salinity for zoea-1 to zoea-3 stage of 32-34 ppt and zoea-4 to megalopa stage
of 28-30 ppt; and C: salinity zoea-1 to zoea-3 stage of 28-30 ppt and zoea-4 to
megalopa of 24-26 ppt. The treatment A resulted highest survival rates, and
growth rate of megalopa. The survival rate of treatmet A, B, and C were
23.08±4.01%; 17.23±3.41% and 11.54±1.41%, respectively
