Lake Whitefish from Lake Superior

This is a Lake Whitefish (Coregonus clupeaformis) caught through the ice on Lake Superior, yesterday. The presence of an adipose fin (between the dorsal and the caudal fins), among other characters, indicates its close relatedness to other salmonid fishes of which we also caught (in the same area) Rainbow Trout, Coho Salmon and Lake Herring.

All of these species feed heavily on Rainbow Smelt (Osmerus mordax), an invasive forage fish in Lake Superior.

This is one of my favourite fish to eat.
