This study will determine tumor prevalence and examine possible associations between tumor prevalence and contaminant exposure to PCBs and PAHs within the Massena/Akwesasne AOC. Brown Bullhead are a species of choice due to their abundance, bottom-feeding and sediment burrowing behaviors, tolerance, human consumption concerns for bioaccumulation, and prevalence across the Great Lakes nearshores. Brown Bullheads are commonly affected with epidermal neoplasms of the mouth and skin, where neoplasms are defined as an abnormal tissue that grow by cellular proliferation to form a distinct mass of tissue that may be papillomas (benign) or carcinomas (malignant). Information will be used in assessing the delisting of Restrictions on Fish and Wildlife Consumption and Fish Tumor and Other Deformities BUIs. Sampling will take place over a period of two years (2012 & 2013). Fish will be analyzed for age determination, histology, liver neoplasia and pre-neoplasia.
