  • Title: The need for effective disease control in international aquaculture.
    Author: Hill BJ.
    Journal: Dev Biol (Basel); 2005; 121():3-12. PubMed ID: 15962465.
    Abstract:
    Globally, aquaculture is steadily expanding both in terms of total production and the range of species farmed. At an overall annual growth rate of about 10%, it is by far the fastest growing sector of food animal production in the world and is providing an increasing proportion of the total production of fish and shellfish for human consumption. However, diseases continue to cause significant economic losses in international aquaculture production and to have a detrimental effect on valuable export trade for some countries. Financial losses have been drastic in some cases and the national economies of some developing countries have been adversely affected. Even just at the local level, disease can have a serious impact on the livelihoods and food security of many individual small farmers and their families, particularly in poorer countries. Despite all the problems caused, diseases continue to be spread internationally even where import health safeguards are in place. Recent examples of such spread are presented and some reasons for the appearance of a disease in a country for the first time are given. It is an unfortunate fact that despite many years of damaging economic and social impact of disease in different sectors of aquaculture, and large sums being spent on research around the world, there are relatively few effective and officially approved products available to control or prevent them. Despite the potential market, there are as yet no commercial vaccines available to prevent the damaging effects of many of the most serious diseases. Without such vaccines, it is likely that the serious impact of diseases in international aquaculture will continue for many years to come.
