Effects of nutrients & plane of nutrition on immune response & non-specific disease resistance factors in fish(COMP10/92 - FC0407

R&D Summary Objectives:- Establish for salmonids the role of certain essential nutriants (Vitamins and Zinc) in disease resistance and the effects of diet on defence systems. Key customer purpose:- Provide a better understanding of how diet affects fish health and enable MAFF to recommend guidelines to the salmon farming industry, leading to a reduction in fish disease and costs incurred by MAFF in implementing DFA.
While a well fed fish given a nutritionally adequate diet is a healthy fish there is evidence from mammalian studies that certain essential nutrients have specific effects on immunocompetence and other defence systems. Enhanced dietary levels of these nutrients(vitamin E,A and zinc) may increase disease resistance. The role of these nutrients in disease resistance in salmonids will be established.
