Classification (Williams et al. 1989) Phylum: Arthropoda Class: Crustacea Order: Decapoda Family: Penaeidae Value Commercial: Shrimping has been ranked as the sec- ond most valuable commercial fishery in the , and seventh in quantity (NMFS 1993). landings of all shrimp species combined in the Gulf of Mexico were thousand mt in 1992, and were valued at $ million. Total brown shrimp harvest in the Gulf of Mexico was 64,075 mt in 1991, and brown shrimp typically comprise 57 of the total Gulf of Mexico shrimp landings (NOAA 1993). The fishery for Gulf of Mexico brown shrimp is considered to be fully exploited at this time (Nance and Nichols 1988, Nance 1989), and a longterm potential annual yield of 63,001 mt has been estimated (NOAA 1993). In 1991 an estimated 5,000 offshore vessels were participating in the fishery with an unknown number of smaller boats fishing in the inshore and nearshore waters. The season begins in May, peaks from June to July and gradually declines through April. Major fishing grounds are off the coasts of Texas and Louisiana. Federal regulations have annually closed the offshore fishery along the coast of Texas from around mid-May to mid-July not more than 55 days to allow shrimp to grow to larger sizes (Klima et al. 1982, Klima et al. 1987, Nance et al. 1990). The majority of the brown shrimp are harvested for human consumption. In addition, a smaller bait shrimp fishery also exists (Swingle 1972, Klima et al. 1987, Nance et al. 1991).
