Abstract | Active feeding by a Coregonid species during prespawning run is documented. Alaska Whitefish, Coregonus nelsoni, fed extensively on eggs of least Cisco, Coregonus sardinella, during early October, 1977 in the Chatanika River near Fairbanks, Alaska. Volume of eggs per stomach ranged between 1.5 and 42.4 ml (X = 19.96 ml). Numbers of eggs per stomach ranged between 200 and 7,842 (X - 3,574). Other isolated food items included aquatic invertebrates and vertebrates, and debris. |
