The means for each year of life wer« then averaged by sexes to get the weighted ^rand averau'e calcu- lated length. The termined for each year of life (Tables 1 and 2). These data indicate that male and female striped bass grow at the same rate for the first three years of life. >Subsequently, females grow faster. The greatest difference in annual growth was reached at ages VII and VIII, when it was inches and inches, respectively (Figure 2). (Age VIII is based on a sample of only five fish, so little reliance can be placed in the calculated difference at that age.) The greatest annual growth of both males and females, inches, occurred in the second year of life (Tables 3 and 4, Figure 2). The validity of back calculating growth is confirmed by the similarity between measured lengths at capture and calculated lengths for fish of the same age groups (Table 5). Most of the fish were collected in the fall, after most of their year's growth was completed, but before the annulus was formed. Therefore, measured lengths were compared with calculated lengths of fish a year oldei-. The discrepancy between the third year growth increments found by the two methods was caused by biased sampling of age I-|- and II-j- fish. Age I fish were collected in August, before their annual growth was completed. Moreover, most age II fish were from the upper half of + 15. FIGURE 3.
