During the 1963-64 season, sardines sampled from Baja California were smaller than those from central and southern California (Figure 2). Histori- cally, sardines from Baja California are much smaller per given age and investigators have allied this with serological differences to sub- stantiate the subpopulation theory (Vrooman. 1964). The lengths of sardines in northern Baja California samples ranged from 184 to 258 mm with a mean of 219 mm. Fish from central Baja California were considerabh' smaller, ranging from 160 to 208 mm with a mean of 188 mm (Tables 4 and 5).
