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.
There hasn't been much change in recent weeks. The are still good numbers of Common and Hoary Redpolls around town. Dozens of pairs of Herring Gulls are staking out territory on Skin Island, in Peninsula Harbour.
