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

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,
To evaluate the value of incorporating tail weight and yield in shrimp-breeding programs, the authors carried out a study to estimate heritabilities and genetic correlations for the traits.
The Maricultura del Pacífico hatchery in Mexico uses two-stage selection that controls the pedigree of every animal to minimize inbreeding.
