(ii) Modal class Progression Analysis (MPA) using Bhattacharya's method [26], and included in the FISAT II program [27], allowed to split the observed length-frequency distribution in distributions of distinct cohorts and thus to estimate their mean lengths at (relative) age.
The length-frequency analyses do not allow one to know accurately the age that corresponds to each modal class estimated.
Therefore, the modal class of ~9 cm in May estimated in this study should correspond to the age group 0.
The modal class for both sexes in the first year was 5.5-6.0 cm CW, but the modal classes were different in the second year: for males it was 6.0-6.5 and for females 5.5-6.0 cm CW.
Similarly, Shinozaki-Mendes (2008) also observed that females were more abundant in the modal class and absent in the peripheral classes in a population of C.
[d.sub.1] is the first difference: the frequency in the modal class minus the frequency in the preceding class,
We can identify the modal class by inspection since it has the largest frequency.
The modal classes in the solid-line boxes are linear spaces.
