Commercial shrimp populations were studied during 1967 in nine Texas bay systems, including Galveston Bay. In spring brown shrimp (Penaeus aztecus) were abundant in all sampled estuaries, except the Matagorda Bay complex, and their life-cycle timing was advanced. They reached emigration size by early May and were caught off Gulf passes on May 9. To compensate for the early migration, the closed Gulf season was begun on May 17. White shrimp (P. setiferus) were scarce in summer and abundant in fall. Shrimpers caught 55.5 million pounds of brown shrimp and 6.5 million pounds of white shrimp. More efficient vessels and trawls, increased fishing effort, good weather in summer and the abundance of shrimp were responsible for the large brown shrimp catch. Shrimping activity was set-back by Hurricane Beulah in September, but the industry recovered rapidly.
