Brown shrimp, Penaeus aztecus, first appeared in March samples, reached abundance peaks in June and August, and had emigrated from the bay by September. The maximum modal size of shrimp attained in the bay was 102 millimeters. White shrimp Penaeus setiferus, first appeared in June samples at tertiary bay stations. They reached a peak of abundance in July at secondary and tertiary bay stations. Peak abundance at primary bay stations was in August. Two population waves were noted, in July and again in August or September. A maximum modal size of 126 millimeters was attained in bay nursery areas. Commercial production of brown shrimp (heads on) was 314,700 pounds in 1962, 90,109 pounds in 1963, and 87,347 pounds in 1964. White shrimp production (heads on) was 602,306 pounds in 1962, 359,165 pounds in 1963, and 794,269 pounds from January through October 1964.
