Abstract
There are two ways in which an aquaculturist can increase his yields. The first is by environmental manipulations and the second is by growing genetically improved stock. Aquatic animals allow the implementation of several approaches to genetic improvement. These include hybridization and cross breeding, chromosome manipulation, sex control, transgenesis, and selective breeding. The application of such technologies can be divided into two broad groups: those for short term and those for long term improvement. For instance, it is seldom, if ever, stated that of all the genetic approaches only selective breeding offers the opportunity of continued genetic gain, that the gains made can be permanent. Broadening of the breeding objective to include behavioural traits and selection for multiple environments are areas where much fruitful research and development could be conducted. Thus, the aim of the current paper is to highlight the genetic and advanced reproductive technologies are implemented by the aquaculture industry.
