Adult brook trout (Salvelinus fontinalis) were fed p, p′‐DDT‐ 3 H; 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‐ 3 H in the eggs at the time of fertilization was converted to p, p′‐DDE‐ 3 H and p, p′‐DDD‐ 3 H by the time of yolk depletion in the fry.
