✦ Synopsis

Lake trout (Salvelinus namaycush) of known age from 1 to 12 years were taken from Cayuga Lake in central New York State in 1991 and p,p'-DDE and mercury were determined in their flesh. The concentrations of p,p'-DDE and mercury increased significantly (p less than 0.001) with increasing age of the fish. The concentration of p,p'-DDE also increased significantly (p less than 0.001) with increasing fat content. The concentrations of p,p'-DDE were much lower than those found in Cayuga Lake trout of similar age captured in 1978.

Gross growth efficiency of Lake Geneva brown trout (Salmo trutta) was estimated by monitoring age-related PCB and p,p'-DDE accumulation, food contamination and annual growth. Estimation was carried out using 3-, 4-, and 5-yr old fish. Roach (Rutilus rutilus) were determined as the main component of
