Study: Endocrine Disruption in Bass from Northeast Region Refuges
Date Posted: September 1, 2009Following in the footsteps of a successful investigation of endocrine disruption on the Potomac River, the Service's Northeast Region has developed a region-wide study to examine endocrine disruption in bass. In Maine, smallmouth bass were collected from the St. Croix River near Moosehorn National Wildlife Refuge in September 2008 and will be collected from the Penobscot River near Sunkhaze Meadows NWR in 2009. Plasma will be examined for sex steroids and vitellogenin, and gonads will be examined for sexual maturing and abnormalities.
