Abstract
Size and abundance of pink shrimp (Penaeus duorarum) in and around the Tortugas sanctuary in the Gulf of Mexico were surveyed monthly from September 1981 through July 1983. Samples were not taken in April and June 1983. Shrimp size varied widely at most stations and abundance varied between stations, but the average size increased with increasing depth and abundance decreased with increasing depth. A large proportion of small shrimp (<103 mm total length) in all samples combined monthly were caught inside the sanctuary, but their abundance varied monthly and annually. Small pink shrimp dominated the catch from fewer than half the stations inside the sanctuary in September-December 1981 but increased in abundance and dominated half or more of the stations inside the sanctuary in January-December 1982 and February-May 1983. January and July were the only months in which catches from at least half the stations inside the sanctuary were composed mostly of shrimp at least 103 mm long in 1983. Recruitm...Keywords
