The Status Of Stonecats (Noturus Flavus) In The Laplatte And Missisquoi Rivers, Vermont, Elizabeth Puchala
Graduate College Dissertations and Theses
Stonecats (Noturus flavus, Rafinesque 1818) are designated as a Vermont state-listed endangered species because their known distribution is limited to two systems, the LaPlatte and Missisquoi rivers. The restricted distribution and lack of knowledge on abundance in either river is cause for concern in the continued survival of these populations. Based on the capture numbers and large size range of individuals, we predicted that the population in the LaPlatte River, which provides quality benthic habitat, is stable. However, the Missisquoi River population has the potential for increased intermittent mortalities from two sources, lampricide (3-trifluoromethyl-4-nitrophenol) treatment every four years and dewatering …
