The Bering cisco or Lauretta whitefish (Coregonus laurettae) is a freshwater whitefish found in Alaska and part of Russia. It is often considered to be the same species as the more common Arctic cisco (Coregonus autumnalis).[1][2]
Description
The Bering cisco has an elongate, compressed body. It is silvery-coloured, with a brownish or greenish back. Its
Distribution
The Bering cisco is found in Alaska from Cook Inlet on the south coast to Oliktok Point on the Arctic coast. It occurs on the Yukon River as far upstream as Dawson City, on the Porcupine River, and in the lakes of the Brooks Range. There are some reports of Bering ciscoes from the Chukchi Peninsula and the Kamchatka Peninsula, these presumably being migrants from Alaska.[1][3]
Ecology
The Bering cisco is usually found in river mouths, brackish lagoons, and coastal waters, but may penetrate far upstream.
