Moisture, oil, ash and protein contents of sardine, sea-trout, weakfish and croaker caught in the waters of southern Brazil and landed at Santos were analyzed for 1961. Since no significant differences were found within the species by sex, sexes were not treated separately. Significant variations were found for moisture and oil, but not for ash among the species. The sardine was demonstrated significantly richer in protein and oil than the other species, but it had less moisture. Little or no variation could be shown to occur seasonally, except for oil and moisture in the sardine and oil in the weakfish. However, these results may have been introduced by habitat differences in the samples, about which not enough is known at present to draw strong conclusions.
