Book excerpt: Excerpt from Comparison of Vertebral Counts of Atlantic Menhaden The similarity in the vertebral counts of juveniles in northern estuaries and of spring spawners from adjacent ocean waters further emphasizes the distinctness ofa northern group of fish which appears to be physiologically and genetically adapted to life under conditions of lower temperature. Thus, the inverse re lation between vertebral number and, temper ature noted for many clupeoid fishes (barlow, 1961) does not seem to hold for Atlantic men haden. In the present study, the hypothesis was that no more than two discrete groups of Spawners were present simultaneously in the different localities, and the data confirm that this con clusion, in general, agrees with the known facts concerning the occurrence of spring and autumn-spawned juveniles in estuarine nurseries and the seasonal occurrence of sexually active fish in the commercial catches. Some spawning, however, occurs in waters north of Long Island through summer (herman, Furthermore, spawning by younger, smaller fish occurs from North Carolina south ward beginning in September or October (in advance of the arrival of the larger, older spawning fish from farther northward). The relationship of these additional spawning groups should be investigated as soon as practicable since they must be considered in answering the question of population structure. In view of the results of this study, I recommend that the meristic studies be ex panded to include all known spawning groups. Other meristic and/or mor'phometric characters also should be included to provide estimates of the relative proportions of discrete subpopulation components in mixed samples of fish. Growth, serological, and fecundity studies also should be undertaken since these will yield' ancillary information that, when combined with results of meristic studies, might lead to an understanding of the structure of the Atlantic menhaden population.
