Inbreeding commonly causes a decrease in the mean values of traits of productive interest in aquaculture. Results of a study, however, showed that inbreeding had no effect on grout survival of Pacific white shrimp from 65 to 130 days of age.

Genetic variation for resistance to WSS, AHPND in Pacific white shrimp

Selection for disease resistance has been used in breeding farm animals and can be a viable option to deal with white spot syndrome and acute hepatopancreatic necrosis disease in commercial shrimp culture. In trials, heritability for AHPND resistance was low, while that for WSS was moderate.
