Abstract
Gel electrophoresis was used to measure genetic variation in the orange roughyHoplostethus atlanticus. Samples were collected on the continental slope in the Tasman Sea, South-west Pacific Ocean and North-east Atlantic Ocean, at various periods from 1982 to 1984. Twenty-two enzymatic loci were resolved in seven samples to give observed heterozygosities between 0.104±0.037 and 0.125±0.044. There was little genetic differentiation between populations separated by a distance of approximately 21 000 km. Tasman-Pacific and Atlantic samples differed significantly in allele frequency at only two loci, while at a third locus a rare allele was found only in the Atlantic Ocean.
