The purpose of this study was to quantify the importance of the fathead minnow's (Pimephales promelas) body lipid content and its composition in the bioconcentration of a lipophilic chemical (endrin) from water. For three months prior to exposure, six groups of fish were fed reference research diets containing 0, 10, 15 or 20% (dry weight diet basis) lipids added as corn oil and/or salmon oil. Two other groups were fed frozen brine shrimp (Artemia salina) at two ration levels. Bioconcentration tests at two concentrations of endrin in water produced mean bioconcentration factors (BCFs) of 15,000x after 14 days and 23,000x after 29 days when expressed on a wet weight, whole body basis. Corresponding mean BCFs expressed on a lipid, whole body basis were 190,000x and 340,000x. Whole body BCFs expressed on a wet weight basis ranged 8,000x - 21,000x after 14 days exposure and 5,000x - 30,000x after 29 days exposure. Independent of diet composition, whole body BCFs expressed on a wet weight basis were positively correlated to the concentration of total fish body lipids. When BCFs were expressed on a lipid basis, they were instead negatively correlated to the concentration of total fish body lipids. From the limited number of samples examined for each diet group, no influence of diet lipid source (corn oil, salmon oil and brine shrimp lipids) could be found.
