Shrimp were sampled at six established stations in the San Antonio Bay complex. These ranged from near the mouth of the Guadalupe River to near the Gulf of Mexico. Most habitat types were represented, as related to depth, salinity, turbidity, and vegetation. Brown shrimp were found to appear in April at a size of 50 to 60 millimeters. Only one major wave of browns was detected. These shrimp emigrated to the Gulf after attaining a size of approximately 90 millimeters. Sample catch was more than in 1962, but spread over a much less period of time. White shrimp were found first in June at an average size of 50 millimeters. There were two population peaks detected, one in August and one in October. The first group attained a size of 120-130 millimeters before emigrating to the gulf, and the second wave was about twice as large as the first wave. The commercial bay catch of brown shrimp during 1963 was reported as 90,109 pounds. The catch of white shrimp was reported as 359,165.
