White shrimp, Penaeus setiferus, landings were higher than catches in 1962 by 22 per cent. Brown shrimp, Penaeus aztecus, were most abundant in 10-foot trawl catch in April, May, and June when the shrimp were 60-90 mm long. In 1963, brown shrimp catches with the 6-foot bar seine and the 10-foot trawl were higher than in 1962. In 1963, fewer brown shrimp were caught in 20-foot trawl samples than in 1962. White shrimp increased in 20-foot trawl samples by 8 per cent. White shrimp also showed an increase in 6-foot bar seine samples in 1963. Rainfall was 15 per cent less than in 1962. there were two periods, one in June and one in September, when 5 and 6 inches of rain fell, respectively. Immediately after these periods of rain, juvenile white shrimp were taken in tertiary samples.
