Despite successful growth and prosperity of the past few decades, the U.S. catfish industry is threatened by increasing disease losses, low fish prices, high feed costs and foreign competition. Fish losses due to disease are estimated to cost the U.S. catfish industry $100 million in direct sales annually and are considered the largest impediment to increasing production efficiencies. Objective 1 will provide catfish farmers a better method to monitor biotoxins, pathogens, and pathogen/host interaction in the aquatic environment using new and better surveillance and monitoring procedures coupled with the development of experimental vaccines. Case submissions will also document the prevalence and the emergence of new diseases in the catfish industry. Objective 2 will develop new methods to protect catfish against known disease organisms including antibiotics and vaccines and evaluate the effectiveness of these products to improve disease resistance. New and improved on-farm management programs for the control of trematode infections will be developed. Objective 3 will investigate the prevalence of chemical and mycotoxin feed contaminants in fish feeds and develop methods to detect and control feed contaminants that affect disease resistance of catfish. The overall benefits of this project will be to improve fish health reduce losses due to infectious and non-infectious diseases. The reduction of losses to disease will make catfish farming a more profitable endeavor and increase the competitiveness of U.S. aquaculture.
