Portunus pelagicus is an important crab species for aquaculture in India. Cannibalism
during the megalopa and juvenile stages is a major constraint in standardizing the
hatchery technology of this species. The present study evaluates the efficiency of various
types of shelters in curbing cannibalism in juvenile P. pelagicus. Larvae from eggs of
berried females collected from the wild were reared to first crab instars under controlled
conditions. They were stocked in 200-l tanks at a density of 10/l with shelters of different
materials: (a) nylon mesh netting, (b) seagrass, (c) seagrass and sand, and (d) without
any material as shelter. At the end of the experimental period (15 days), the mean
survival rates of the juveniles in each treatment were subjected to one-way ANOVA and
pairs that significantly differed (p
