STARTER DIET FOR ASIAN SEABASS LARVAE
Seed production of marine finfish in Malaysia is still facing problem particularly live feed for starter diet. Currently, aquaculturists use S or SS type rotifers, which have sizes from 100 to 200Î¼m. Early stage larvae of some marine finfish species select feed less than 100 Î¼m. Protozoa is a collective term of aquatic microorganism that has been identified to be suitable live feed, as their body sizes are less than 100Î¼m. Thus, the objective of this experiment is to compare the survival rates of Asian seabass larvae using four types of live feeds. Four types of live feed; rotifer, protozoa, E. encysticus, and mixed (rotifer, protozoa, and E. encysticus) were used in this experiment. The larvae were fed from 2 to 10 day-after-hatching. Asian seabass larvae were given the same amount of live feed in each larval rearing tank; twice a day. The feeding densities were 20 individual / mL for rotifers, protozoa, E. encysticus, and mixed group. The number of seabass larvae in each group was counted every day, and their survival rates were determined. Starting from 3 DAH until 10 DAH, mixed group showed higher survival rates than other groups. The most recommended live feed was mixed group.
