Individual variability in growth rates may blur age-class boundaries (see text). <br />2 Mean total length was calculated by taking the sum of the products of the mid-point of each length range times the number of fish (n) in each length <br />range, then dividing that sum by the total number of fish (N). <br /> <br />. <br /> <br />. <br /> <br />>-' <br />0--, <br />
