The present paper is a pioneering study on the Brachyura bycatch associated with the artisan prawn fisheries at the mouth of the Amazon River. The study was conducted at four collection sites distributed along the mouth of the Amazon River between the months of January/2009 and January/2010. The animals were caught using handcrafted traps called "matapi", which are used by prawn fisherman in the region. Twenty matapis were used at each collection site. A total of 145 specimens were captured and six species were identified, all belonging to the Trichodactylidae family - Sylviocarcinus maldonadoensis, S. pictus, S. devillei, Valdivia serrata, Dilocarcinus septemdentatus and D. pagei. The most representative species, S. maldonadoensis, S. pictus and S.... |

Os macrocrustáceos que ocorrem nas partes rasas do complexo lagunar Mundaú/Manguaba foram estudados entre maio de 1988 e abril de1989. As amostragens foram realizadas com rede de arrasto de praia. Foi capturado um total de 15 espécies pertencentes a 6 gêneros e 3 famílias. Baseado no CPUE, as espécies que predominaram em número foram: Palaemon pandaliformis, seguido por Macrobrachium acanthurus e Callinectes danae. Com relação à biomassa, as espécies dominantes foram: C. danae, seguido por C. bocourti, P. pandaliformis, M. acanthurus e C. ornatus. Análises de agrupamento por mês e estação de coleta evidenciaram a associação de dois grupos de espécies: um dominado por portunídeos e outro por palaemonídeos. Como os macrocrustáceos representam importantes... |

Le programme d'amélioration des techniques d'élevage de la Chevrette Macrobrachium rosenbergii en Guyane constitue la deuxième phase du programme d'expérimentation mené sur la station IFREMER de Kourou. Jusqu'en 1988, l'effort a porté sur l'analyse du système continu classique utilisé par l'ensemble des producteurs de Macrobrachium aux Antilles et en Guyane. A partir de 1988, il apparut que la résolution des problèmes posés par son application passait par l'utilisation de schémas de gestion de la population en mode discontinu. Les expérimentations ont donc porté sur les principales conditions d'élevage susceptibles d'améliorer l'efficacité du schéma d'exploitation de la population. En prégrossissement, il s'agissait d'obtenir le meilleur compromis... |

The embryonic development of four species of the family Palaemonidae was studied under laboratory conditions. Adults of Macrobrachium olfersi (Wiegman, 1836), Macrobrachium potiuna (Müller, 1880), Palaemon pandaliformis (Stimpson, 1871) and Palaemonetes argentinus (Nobili, 1901) were collected in Santa Catarina Island, Santa Catarina, Brazil and maintained at 26ºC. The following embryonic characters were analyzed: egg shape, yolk organization and cleavage plane, naupliar and post-naupliar appendages, stomodeum, optical lobes, eyes, telson, embryo curvature and the space occupied by the embryo in the egg. Different rates of development were observed for the four species, with M. potiuna showing the longest time of embryogenesis. The species studied followed... |

In this paper, female Macrobrachium carcinus (Linnaeus, 1758) maturation curve, weight/length relationship, length and weight growth curves were studied. Prawns were captured, by traps, in Ribeira de Iguape river (24ºS and 47ºW), southern Brazil. There were used 207 females. It was observed that M. carcinus presents several spawnings during its life cycle and reproductive period goes on, at least till six years old. Weight/length relationship can be represented for the equation W = 8.73 E-3 L3.28. Expressions obtained for length and weight growth curves are Lt = 21 .0 (1-e-0493t) and Wt= 190 (1-e-0493t)3.28. respectively. A symptotic maximum length and asymptotic maximum weight are nearly attained at six and eight years old, respectively. |
