However, it does appear prominently in the leniith frequency distributions of the past 40 years. There is p'ood apreenuMit between the modal lengths and the mean lengths of the assigned age groups. The results of this study have been summarized for the three months of the investigation (Table 1). From the stratified sample of 396 scale samples, 324 were read and assigncnl to age groups. ]\Iean length, stand- ard deviation, and standard error of the mean were calculatetl for each group. Early in the investigation it was hypothesized that the fleet captured only the largest fish of the first modal group.
