Abstract
This study reviews methods formerly recommended for discriminating between the alewife (Alosa pseudoharengus) and blueback herring (A. aestivalis) and suggests an alternate, more efficient, external species-specific character. The method relies on differences in scale imbrication patterns and scale morphology.Key words: alewife, Alosa pseudoharengus; blueback herring, A. aestivalis; morphology, meristics, identificationThis publication has 0 references indexed in Scilit:
