Abstract
    The northeast Atlantic lesser sandeels Ammodytes marinus Raitt, Ammodytes tobianus L. and Gymnammodytes semisquamatus Jourdain were screened by starch gel electrophoresis for species-specific enzyme variation. Morphological separation of the genera is reliable but distinguishing the two Ammodytes species is problematic, particularly in smaller specimens. The analysis revealed a number of diagnostic isozymes. Two, MEP-1 and MEP-2, appear particularly suitable for discriminating the three species. These isozymes show no intraspecific variation, can be typed using muscle, are relatively stable in frozen tissue, and can be resolved using a single gel and histochemical stain. The use of these diagnostic isozymes will facilitate species discrimination in fisheries assessment work and in studies of the ecological differences among the species.
