The Degradation of DDT in Brook Trout Eggs and Fry

Abstract

Adult brook trout (Salvelinus fontinalis) were fed p, p′-DDT-3H; eggs obtained from these fish were fertilized, and incubated; and the developmental stages were analyzed for the degree of metabolism of the DDT. About 35% of the p, p′-DDD-3H in the eggs at the time of fertilization was converted to p, p′-DDE-3H and p, p′-DDD-3H by the time of yolk depletion in the fry.
