is 500 individuals m
−2
which a 25 % is decreased through regular size grading, over
a 10-day period. The young are fed from hatching to about 30 days with live prey
organisms either collected from the wild (mysids) or produced in hatchery (penaeid
shrimp postlarvae). The active habit of the young causes this species to be able to
accept dead feed in a shorter period, compared to S� pharaonis. Survival is more
than 90 % 2 months after hatching. Growout in an earthen pond is feasible. Overall
daily growth rate is approximately 2.4 % in length and 6.0 % in weight. The mean
final size and lifespan is approximately 50 g, for 115 days in open seawater systems
at 28°C. Innate feeding on specific live preys is the bottleneck and development of
artificial feed is required in the long term.
