- Abstract
Genetic variation as identified by starch gel electrophoresis and enzyme staining was studied in seven populations of the northern pike, Esox lucius L. Samples derived from populations in northern U.S., Canada, Swedish fresh water, Swedish Baltic, the Netherlands, England and Ireland were analysed for variation at between 10 and 26 enzyme-coding loci. Polymorphism was found to be restricted to three loci: Sod-1 (mitochondrial superoxide dismutase), Ldh-2 (heart-type lactate dehydrogenase) and Got-1 (cytoplasmic glutamateoxalate transaminase). Mean heterozygosity ( H) over all seven population samples was estimated to be 0·019. This extremely low variability, relative to reported data for other fish species, is discussed in terms of the structure and possible origins of pike populations.
