This report deals with the growth, seasonal abundance, and movement of brown shrimp, Penaeus aztecus, and white shrimp, Penaeus setiferus, in the coastal bays of Texas in 1965, including Galveston Bay. Young brown shrimp were abundant in the spring. Apparently, unfavorable bay conditions forced the young to enter the Gulf at an unusually small size. The fairly high brown shrimp population level in the estuaries after June 1 was indicative of a long emigration period and a strong year-class. White shrimp samples were small in the summer, but a large group was recruited to the population in the fall. The brown shrimp commercial catch in the spring (from major bays) increased 75% over 1964. White shrimp catches were small in August and September, but increased sharply in late fall. The total 1965 Texas shrimp landings, which nearly equalled the large 1960 catch, were over 48 million pounds, headless. Annual brown shrimp landings increased 31% from 1964, but white shrimp landings decreased 21%.
