What is a siscowet lake trout and what impact do they have on the fishery?
A. The siscowet lake trout is a deep-water form usually caught at depths greater than 300 feet. Siscowet are less desirable because of their high fat content and they are of limited food value due to high contaminant levels. Because siscowet were not as susceptible to lamprey, their numbers remained relatively high during the decline of lean lake trout. Siscowet are the most abundant predator in Lake Superior. There is evidence that siscowet rely on nearshore production for a significant portion of their lives and they therefore may compete with lean lake trout for resources.
