Application of gene transfer technology for genetic improvement of fish

The worldwide decline of natural fish stocks, the accumulation of chemical pollutants in aquatic environments and increasing world consumption of fish products has provided an impetus in many countries for a rapid growth in aquaculture. Fish produced from aquaculture currently account for over one-fourth of fish consumed by humans. However, success in aquaculture mainly depends on breeding, feeding and protection from disease. Application of recombinant DNA technology in aquaculture can help to improve these requirements.
