ABSTRACT:
Environmental scientists and managers often use tumor surveys with freshwater, estuarine, and
marine fish as indicators of habitat quality. In 2002-2004, we collected mummichogs (Fundulus
heteroclitus, > 70 mm total length, n = 21-30 per location) from four areas within the Delaware
Estuary watershed. Necropsies were performed and livers and raised skin lesions were examined
histopathologically for tumors and preneoplastic lesions. |
