Reports on the dramatic declines in commercial and recreational fisheries for coho salmon in Lake Superior which have raised questions about the natural factors that limit their productivity. Snorkeling surveys were conducted during the winters of 1995?96 and 1996?97 to estimate over-winter mortality and determine winter habitat use by juvenile coho salmon in two spring-fed tributaries of Chequamagon Bay, Lake Superior. |
