Glucosephosphate isomerase and isocltrate dehydrogenase polymorphisms in the hake,Merluccius australis

Abstract
As part of a stock separation programme on the hake, Merluccius australis (Hutton), two polymorphic proteins — glucosephosphate isomerase and isocitrate dehydrogenase — were examined in four samples of fish from around the South Island of New Zealand and the waters to the south. No significant differences in allele frequencies were found between the four areas, and with evidence from biological data it appears that there is one major stock of M. australis around New Zealand.
