Gonadal Deformities in Smallmouth Bass as Indicators of Endocrine Disruption in the St. Louis River Estuary
Document the occurrence and prevalence of testicular oocytes and other altered gonadal morphology in smallmouth bass generally, specifically from the St. Louis River estuary. These goals will be accomplished using two research components: 1) a histological analysis of gonadal tissue from smallmouth bass collected in field surveys of sites in the Lake Superior watershed and northern Minnesota; and 2) laboratory studies to document early gonadal development in smallmouth bass in the presence and absence of a controlled exposure to a known estrogen.
