Cross Breeding

Crossbreeding is the solution of inbreeding depression, because the fishes are allowed to breed with different breed verities, strains or genotypes of farmed species. To improve the stocks artificial selection techniques are applied. This is called selective breeding. From heterozygosis the stocks can be improved and the aims of cross breeding to achieve –
· Better growth rate
· Better desired qualities
· Better FCR value
· Increase the survival rate and lowered the early stage of mortality
