A biochemical genetic study of population structure in queen scallop ( Chlamys opercularis ) stocks in the Northern Irish Sea

Duggan Department of Marine Biology University of Liverpool, Marine Biological Station Port Erin Isle of Man, UK Abstract Electrophoresis was used to survey a number of enzymes for loci of potential value as stock markers in Chlamys opercularis (L.). Two loci, Pgi and Pgd , were then studied in larger samples from each of two localities around the Isle of Man. One Pgi allele was found to be restricted to a particular year-class in both populations.

Two loci, Pgi and Pgd , were then studied in larger samples from each of two localities around the Isle of Man. One Pgi allele was found to be restricted to a particular year-class in both populations. This was confirmed by subsequent studies of three further populations, in each of which the same allele occurred only in the one year-class.
