Size Distribution of Pink Shrimp, Penaeus Duorarum, and Fleet Concentrations on the Tortugas Fishing Grounds

Résumé du livre

A study of the pink shrimp, Penaeus duorarum, on the Tortugas fishing grounds was undertaken during 1957 and 1958 to provide information on the nature of the relation between the size of shrimp and the depth of water where they occur, together with fleet concentrations and degree of discarding of small pink shrimp. The average carapace length of both male and female shrimp increased both with depth of water and with northerly distance from the Florida Keys. Small pink shrimp were most abundant from September 1957 through May 1958, appearing on the eastern and southeastern portion of the grounds, where the highest try net catches were made. The fleet concentrated there during December to June but was more widely distributed during the summer. Apparently, few small pink shrimp were discarded.
