Capelin. A small bony fish of Arctic waters, resembling smelt and with the same cucumber smell when fresh, and treated in the same way as whiting.
Polar cod, so similar to cod as to be almost indistinguishable but from the far north.
Char(r) usually refers to the Arctic char, an uncommon freshwater fish of the same family as salmon, trout and related to grayling and the vendace or powan. It is found in rivers and lakes of northern Europe, north western United States and Canada and in the Great Lakes. They are migratory fish, like salmon and trout. They have a steely blue-grey back with salmon-pink speckles on the sides and a red underbelly. They have sweet firm flesh which varies from white to pink, dependent upon its own diet, and with good flavour, some say better than trout, being something like a cross between trout and salmon.
