One of the important factors determining the success in open sea floating cage farming is the availability of quality seeds of
appropriate size. The commercially available hatchery produced seeds should be further reared to appropriate size before
stocking in the sea cages. The Asian seabass, Lates calcarifer is an important candidate species for open sea floating cage
culture. Availability of seeds of required size is an important bottleneck in the sea farming of this species. To address this
issue, an experiment was conducted in 2007 off Visakhapatnam coast of India in the Bay of Bengal, to study the effect of
different stocking densities on the growth and survival rate of hatchery reared seabass fry. Asian seabass fry with a mean
total length of 23.9 ±3 mm and mean body weight of 0.45±0.05 g were stocked in 5 t FRP tanks with 3.5 t of filtered seawater,
at three different stocking densities viz., 1000, 1500 and 2000 nos. m-3 in triplicate. The fishes were fed with commercial dry
pellet feed (Godrej) at 6-8% of fish biomass. Feeding was done 6 times daily at 4 h intervals . The water quality parameters
were monitored and maintained within the favorable ranges for seabass culture. The growth and survival under different
stocking densities were monitored for a period of 90 days. Results observed from these experimental trials showed that the
specific growth rate (SGR) was inversely proportional to that of the stocking density (p
