Technical Abstract: This article summarizes several elements of genetic improvement in aquaculture. It begins by introducing the idea that domestication is the first step in genetic improvement. The topics of classical selective breeding, genetic marker assisted selective breeding and finally genetic engineering (chromosome set manipulation and transgenesis) are presented. The advances in classical quantitative genetics and integration with marker technologies are described, followed by a discussion of the use of genetically engineered organisms such as triploids and transgenic plants and animals. The need to improve multiple traits simultaneously is pointed out as an ongoing challenge for genetic improvement.
