In 1968, landings of 292 million pounds were worth about $113 million to fishermen. About 70% of this catch came from the Gulf of Mexico. Consumer demand for shrimp, either as food or bait, is increasing at a rapid rate. But landings of shrimp from the Gulf of Mex- ico, with few exceptions, have remained relatively constant over the past 10 years. The increased demand for shrimp is re- flected by increased imports. To supplement this important fishery, and to offset rising imports, BCF began studies in 1964 to de- termine the economic feasibility of shrimp farming. Although shrimp mariculture has been common abroadfor many years, notably in Japan, it is still on an experimental basis in the ' Ik ^^-^^ 4v^;^«- BCF biologists penodically sample shnmp grown in 1/16-acre ponds at Galveston, Texas, to obtain information on length and weight increases. These data willhelp determine the economic feasi bility of shrimp farming in the Studies underway maybe divided into larval shrimp culture and juvenile shrimp culture. The young shrimp, immediately after it hatches, is called a larva and is free floating in the water. The older, juvenile shrimp, however, lives on the sea floor. The physiological requirements of larval and juvenile shrimp vary considerably; each phase of research has separate and distinct problems related to the age of the shrimp. Culture of Larval Shrimp Until a few years ago. Gulf shrimp had never been hatched and reared to the juvenile stage in the Bureau scientists hav
