Effect of Aroclor 1254 and Mirex on Estradiol-lnduced Vitellogenin Production in Juvenile Rainbow Trout (Salmo gairdneri)

Abstract
A rapid sensitive assay for vitellogenin using rocket immunoelectrophoresis was developed in juvenile rainbow trout (Salmo gairdneri) induced with 17β-estradiol. The assay detected vitellogenin serum levels as low as 0.05 mg/mL. Significant reduction of vitellogenin levels were detected in rainbow trout fed for 6 mo on diets contaminated with Aroclor 1254, Mirex, or a mixture of Aroclor 1254 and Mirex.
