摘要: In yellow perch (Perca flavescens) (initially 13–16 g total weight) fed to satiation (3.0–3.5% of body weight per day), estradiol-17β (E2) at 15 μg/g diet stimulated gain and food consumption both sexes but did not influence conversion efficiency (FCE), as measured by fish consumed. Females gained more weight, consumed food, had higher FCE than males. a restricted ration (1.2% the differences between in were reduced due entirely FCE, was improved E2. Spatial segregation or integration no on sex-related growth patterns either ration. Carcass composition treated for 84 d with E2 2, 20, 50 μg/g differ from that controls. These data indicate (1) estrogens promote stimulating consumption, (2) female p...
