Populations of Juvenile Shrimp in the Lower Laguna Madre - Study of Texas Shrimp Populations

Groover shrimp, Penaeus aztecus and P. duorarum, were the most abundant shrimp in the lower Laguna Madre in 1962 and were present from March to December 1962. They were most abundant in August, October and November. Grooved shrimp were found in the open areas of the bay, while white shrimp were found primarily in sloughs and backwaters which connect with the bay. Jackass shrimp, Trachypeneus sp. and the sea bob, Xiphopeneus kroyeri were abundant in the deep waters of the Brownsville Ship Channel during the winter.
