Abstract

Aquaculture is an ancient form of farming dating back 2000 years or more in China and the Roman Empire. Due to the continuing depletion of the fish stocks, it increased the demand for aquacultured foods and more efficient production systems. As the space for aquaculture has gradually become more limiting, the need for more efficient production or increased production within the same amount of space will further increase the importance of the genetic improvement of aquatic species. Aquaculture could help to meet increasing demand, and biotechnology can make a great contribution to improve aquaculture yields. The potential areas of biotechnology in aquaculture include the use of synthetic hormones in induced breeding, production of monosex, uniparental and polyploid population, transgenic fish, gene banking and health management. Since the 1980s, several aquaculture species have been greatly improved in number of traits such as growth rate, feed conversion efficiency, resistance to disease, increased tolerance to water of low quality, tolerance to cold, body shape, fertility and reproduction. However, there is need for the regulation of biotechnology activities in terms of the potential adverse impacts on the environment and human health. If properly implemented, biotechnology in aquaculture has a positive effect on the environment by producing healthy and fast-growing aquatic species. Several constraints will need to be overcome for aquaculture genetics to have its maximum impact and benefit in the future.
