Morphometries of Three Sympatric Arctic Codfishes of the Genera Arctogadus and Gadus
Three populations of codfishes inhabit the waters of Cambridge Bay: two belong to the genus Arctogadus, the third is Gadus ogac. In spite of phenotypic resemblances of some Arctogadus specimens to Gadus, the two genera are well separated as indicated by significant (P < 0.05) differences in o...

Three populations of codfishes inhabit the waters of Cambridge Bay: two belong to the genus Arctogadus, the third is Gadus ogac. In spite of phenotypic resemblances of some Arctogadus specimens to Gadus, the two genera are well separated as indicated by significant (P < 0.05) differences in otolith shape. Significant differences in 15 out of 27 morphometric characters and in two out of 10 meristic characters, and a different sexual dimorphism indicate that the separation of the Cambridge Bay Arctogadus stock in two populations is valid; these populations correspond respectively to the described species A. borisovi and A. glacialis. |
