Present
study reveals the variation in wet weight at harvest (4 months in pond) and
resistance to white spot syndrome virus (WSSV) in the Kuruma shrimp Marsupenaeus
japonicus. Eight families obtained from gravid female shrimp from wild and
two inbred families were used. Representatives from each family were challenged
with White Spot Syndrome virus. Survival curves in a challenge experiment
revealed no difference between wild and inbred families. However, one family
each from wild and inbred had higher median survival compared to the rest.
Analysis of the wet weight at harvest revealed sexual dimorphism for growth
with females weighing heavier than their male counterparts. Heritability was
estimated sex-wise for harvest weight using full-sib correlation method. The
estimates indicate that harvest weight would respond readily to selection.
