OBJECTIVES AND EXPECTED ACHIEVEMENTS
In view of the concern of reducing the level of dioxin in the food chain, focus has been placed on levels found in animal feed and those transferred to human food. Particular interest has focused on fish as a vehicle which can carry high loads of dioxin picked up from the natural environment in which the fish is living.
The purpose of this research is to examine the uptake of dioxin by fanned salmon from salmon feed during the growth of the salmon from 1.3kg to approximate 4kg market weight. Four salmon feeds with graded levels of dioxin prepared using mainly fish meal and fish oil; the latter are of high or low dioxin concentrations and different blends are to be tested. Dioxin, PCBs and heavy metals (contaminant) levels will be determined in the feed and in the salmon after 15 weeks and 37 weeks feeding experiments when the fish will have reached approximately 2kg and 4kg in weight.
