Mexico and the United States share shrimp and other marine resources in the Gulf of Mexico. As a result, in 1977 a cooperative research agreement was established between the Federal fisheries research organizations of the two countries - the Departmento de Pesca's Instituto nacional de Pesca (INP) and the National Marine Fisheries Service's (NMFS) Southeast Fisheries Center - to develop a joint marine research program. This report summarizes the first seven years' results from this cooperative research and suggests the direction of the program for the next two years (1985-86).
