Transgenic fish: risks and benefits

Abstract

Advocates of transgenesis consider it an effective means of improving the productivity of aquatic animals. Opponents see it as a threat to both the environment and human health. This is a challenging area because important traits in fish are complex and controlled by multiple genes. Nevertheless, some transgenic lines of "high-growth" tilapia, salmon and carp are nearing the stage at which they could be considered for commercial production.
