Abstract
Abstract: 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 trout diet. Estimated growth efficiency coefficients were 0.4 (3–4 yr old fish) and 0.17 (4–5 yr old fish). Nevertheless numerous parameters can affect the result; their respective influences are discussed. Related to fish age, PCB and p,p′-DDE concentrations increase if expressed on a wet weight basis, but not if expressed on a lipid weight basis. At the same age, organochlorine residue concentrations keep similar values for trout and roach in spite of different trophic levels. Growth must be considered as a more dilution factor of PCB and p,p′-DDE in trout compared with roach.
