"Research on penaeid shrimp stocks in the northern Gulf of Mexico began in 1977 as part of Project MEXU5-GULF and continued in 1978. During the 1978 phase, brown shrimp (penaeus aztecus) were the target species for mark-recapture studies. Expanded operations were initiated in Louisiana, both in Caillou Lake and offshore, in an attempt to characterize the brown shrimp stocks of the north central Gulf of Mexico"--Introduction, paragraph 1.
