UBC Institute of Fisheries Field Record B.C. 58-561


This is the first record of C. clupeaformis from Alaska. Walters (Bull. Amer. Mus. Nat. Hist. 106 (5), 1955), says of the species "Not known to occur west of the MacKenzie, though possibly it may be found replacing Coregonus laveretus pidschian (Gmelin) in easternmost Arctic Alaska." The latter species has been recorded from the Colville river. Probably these two "species" intergrade, but in the present state of whitefish taxonomy the only known distinction between them, gill raker count, places this specimen definite as C. clupeaformis. (There are 24 gill rakers in the first arch).; C14 Coregonus clupeaformis (Mitchill) [handwritten note] NMC (1), Field No. EBR 489; C14 Coregonus nasus (Pallas) [handwritten note] NMC (2)
