There is an increasing demand for fish in the world due to a growing population, better economic situation in some sectors, and greater awareness of health issues in relation to food. Since capture fisheries have stagnated, fish farming has become a very fast growing food production system. In this presentation, the author gives an overview of the technologies that are available for genetic improvement of fish, and briefly discuss their merit in the context of a sustainable development. He also discusses the essential prerequisites for effective dissemination of improved stock to farmers. It is concluded that genetic improvement programs based on selective breeding can substantially contribute to sustainable fish production systems. Furthermore, if such genetic improvement programs are followed up with effective dissemination strategies, they can result in a positive impact on farmers' incomes.

The current situation is that, by any measure, most fisheries worldwide are fully over exploited. This is also true of the Uganda's fisheries where the effort needed to catch fish has increased, and the average size of fish and of stocks have both declined. A productive fisheries offers many benefits: food for local consumption; raw materials for industry; employment that generates income, which in turn encourages other industrial, commercial and service activities; export markets that can be identified and met to generate hard currency, The national economy also benefits from import substitution and·opportunities for increased taxation. But for fisheries to be productive it is not enough to produce, products must be marketed. Fishers have to learn the lesson that it is no longer enough to expect production to drive the market; success will come from producing what the market demands. It is hoped that co-management can play a big role in harnessing the various energies for sustainable development and management of the fisheries resources.
