摘要: Brown trout, Salmo trutta, exposed to heavy metals (mainly Cd and Zn) for at least 2 years in the Eagle River, Colorado, were examined liver size activity of growth-promoting enzyme, ornithine decarboxylase (ODC) compared trout living an uncontaminated site. Liver-somatic index (LSI) was greater site with LSI females being significantly than that males. The contaminated site, but males not different statistically. ODC livers both lower However, did differ respect activity. These data suggest chronic exposure may have important implications growth reproduction possibly survival. might serve as a useful biomarker when assessing toxicity naturally reproducing fish populations.
