Various environmental alterations have been identified
to control the reproduction in Nile tilapia. For examples,
low temperature, high salinity and photoperiod . However, no suitable system or
strategy has been developed so far possibly due to the low
efficiency of these factors and the higher costs involved.
Present findings showed that suitable combinations of
stocking density and restricted feeding strategy might help
manipulate timing of seed production according to the fry
demand. In this study, stunted (S) broodfish were smaller
than the normal (N) group at stocking because of limited
feeding and rearing in crowded condition prior to
maturation.
