Item Growth and mortalities of the Pink-shrimp(2006-05) N . O ., Leite JR LEITE; JR . , PetrereFrom July, 1999 until July, 2001 data from the pink-shrimp Farfantepenaeus brasiliensis Latreille, 1970 and F. paulensis Pérez-Farfante, 1967 fishery were collected from trawling by the fishing fleet based in Santos/Guarujá-SP. Growth and mortalities of these species were studied. F. brasiliensis and F. paulensis have longevity of 2 years and growth estimates of L∞ = 29.0 cm and k = 1.24 year-1 for F. brasiliensis and L∞ = 27.5 cm and k = 1.34 year-1 for F. paulensis. Females reach bigger lengths than males in both species. Natural mortalities (M) were 1.80 and 1.90 year-1 and fishing mortalities (F) were 4.7 and 6.8 year-1 for F. brasiliensis and F. paulensis, respectively. Survival rates are S = 0.15% and 0.02% for F. brasiliensis and F. paulensis, respectively, which are usually low values for shrimps.Item REABILITAÇÃO DE TARTARUGAS MARINHAS NAS BASES DO PROJETO TAMAR – ICMBio, NA COSTA BRASILEIRA(2008) WERNECK, M. R.; TADASHI, E.; PIRES, T. T.; MELO, M. T. D.; CASTILHO, J.; BAPTISTOTTE, C.O Projeto TAMAR-ICMBio, atua desde 1980, com o objetivo de proteger as espécies de tartarugas marinhas na costa brasileira. Bases de campo foram implantadas em áreas de desova e áreas de alimentação, onde são encontradas cinco das sete espécies existentes no mundo: Caretta caretta, Chelonia mydas, Eretmochelys imbricata, Lepidochelys olivacea e Dermochelys coriacea.Item Stock assessment and fishery management of the pink shrimp Farfantepenaeus brasiliensis Latreille(2006-02-28) LEITE , Junior JR . , N . O; M , Petrere . JR PETRERE; N.O, Junior JR LEITE; M , Petrere . JRQuantitative analyses of the pink shrimp (Farfantepenaeus brasiliensis and Farfantepenaeus paulensis) fisheries were carried out using data collected from July 1999 to July 2001 from the trawling operations of the fishing fleet based in Santos/Guarujá, SP. According to classical models, the fishery is at its maximum sustainable yield. Therefore, reduction of the fishing effort and adequate season and area closures seem to be the best management actions for the pink shrimp fishery.
