Abstract

Inbreeding occurs when individuals of related ancestry are mated which results in a reduction of heterozygosity in a population. Penaeid shrimp production usually needs a low number of broodstock to produce the millions of progeny required per production run. This can lead to an increased risk of inbreeding when pedigree records are not available or are incomplete because hatcheries often buy shrimp broodstocks from a few sources, e.g., capture fishery shrimp trawlers. The attempt to use these stocks and their descendants as breeders for subsequent generations can result in inbreeding. This chapter provides a number of examples of inbreeding in cultured crustaceans and some principles on the management of this potential health problem.
