title: Retina-specific LDH isozyme in blueback herring, Alosa aestivalis (Mitchell), and alewife, Alosa pseudoharengus (Wilson).
abstract: The retina of 390 Alosa aestivalis and 410 Alosa pseudoharengus have been examined by means of starch-gel electrophoresis. The retina-specific E4 isozyme has been found to occur in all the fish examined. This study demonstrates for the first time that the E4 isozyme occurs in A. aestivalis. Because the E4 isozyme is not polymorphic and has an identical mobility in A. pseudoharengus and in A. aestivalis it is neither suitable for use as a species identification characteristic nor a population marker.
