Abstract

Cannibalism within different size group of sea bass Lates calcarifer fry has been
studied under hatchery rearing conditions. The mean cannibalistic percentage
was high, when large and small size group (21.8 + 1.60mm and 11.6 + 1.02 mm,
6.8 + 0.75 mm and 11.6 + 1.02 mm) were reared in the same container. Higher
rate of cannibalism was observed without feed than with feed and increased
with duration of rearing. When the same size group fry were reared, rate of
cannibalism was significantly low in all the size groups. The results indicated
the importance of gradation and frequent feeding for better survival and growth
of seabass fry during hatchery rearing
