Muscle protein differences in two eels Anguillaanguilla (Linnaeus) andAnguilla rostrata (Le Seuer)

The taxonomic and genetic relationship of the two nominal species of catadromous Atlantic eel poses the question whether or not each eel species has one independent and recognizable gene pool. The positive answer to this question is reinforced by comparing the isoelectric points of muscle proteins in samples of eels from two freshwater sources, one in Nova Scotia, Canada, the other in East Anglia, England. Particular proteins are exclusive to each species sample.
