| The objective of this study was to get some knowledge about the reproductive aspects of Goniopsis cruentata (Latreille, 1803), concerning through sex ratio, morphological sexual maturity, reproductive period, fecundity and eggs size. The crabs were collected monthly in Itacuruçá's Mangroves from November, 1997 to November, 1998. Four hundred and seven crabs were caught and they were 47% males, 36% females and 17% ovigerous females. The sex ratio was 1:1.13 (male:female) (X²= 1.54, p > 0.05). The relation of abdomen width (AW) and carapace width (CW) in females showed a positive allometric grow (b = 1.36), it suggests the size onset of maturity occur from 26.0 a 29.0 mm (CW) in females. The ovigerous females occured during all the research period, except... |

| The objective of this work has to get knowledge about the reproductive aspect of the tree crab Aratus pisonii (H. Milne Edwards, 1837). The sampling were made monthly from April, 2000 to April, 2001, in the Itacurucá's mangrove (22º54'S and 43º33'W), Rio de Janeiro. The crabs were collected handly, using an effort of 50 minutes with three collectors. In laboratory, the specimens were separated by sex and had measured the carapace width and lenght. The ovigerous females were separated and the mass of eggs was removed for a mensurament of size and count of eggs. Afterwards, the animals were conservad in 70% alcohol. A total of 783 individuals were caught among 59% males and 41% females among these 8% were ovigerous. The ovigerous females were found almost... |

| The reproductive cycle of the marine catfishes Genidens genidens Valenciennes, 1833 and Cathorops spixii Agassiz, 1839 in the Sepetiba Bay, was assessed by an annual period of sampling from October 1993 to September 1994. The fishes were caught by standardized otter trawl and environmental parameters of temperature, salinity and transparency of water were recorded at each sampling. Five gonadal phases were described, based in macroscopic observations. Changes in the gonadosomatic index (GSI) and in the percentual of stages of gonadal development showed that G. genidens spawns in Summer/early Autumn, coinciding with low salinity and high temperature and transparency. Cathorops spixii spawns in late Spring/early Summer, coinciding with rising temperature and... |

| Abstract:Farfantepenaeus brasiliensis and F. paulensis are the most exploited shrimps of SE-S Brazilian coast. Our aim was to verify if adjacent nursery areas with different environmental condition (Sepetiba and Guanabara bays, SE Brazil) influence on shrimp populations (eg, CPUE) and body shapes. Samplings were carried out during 12 months in those bays ca. 85 Km far from each other. Carapace length (CL), total body length (TL), wet weight, abdomen size and TL/CL ratio were used to analyze variations in shape through regressions. In general, F. brasiliensis was 4 to 6 times more abundant than F. paulensis. The sex ratio differed from 1:1 in F. brasiliensis in both bays, with dominance of females, largest catches occur in autumn. However, differences in... |

| The silverside, Atherinella brasiliensis (Quoy & Gaimard, 1824), a resident species of the shallows of bays, estuaries and coastal lagoons, was studied during two annual cycles, using beach seines (July 1996 to June 1998), in the continental margin of the Sepetiba Bay, aiming to assess recruitment and distribution patterns. A wide recruitment period, with young-of-the-year appearing from early spring to early autumn, was shown, with peaks of juveniles (Total Length-LT = 10-30 mm) being recorded in two periods of the year; one in November and another in March. The highest abundances, of both juvenile and adults, were recorded in Coroa Grande and Itacuruçá, sites located in the outer Bay, during the whole summer, with significant differences were... |

| Coastal river plumes represent one of the final stages of material transport across the land-sea interface. Most studies, however have focused on the behavior of medium to large sized river plumes of coastal-shelf waters, whereas small sized river plumes acting within estuaries have been neglected. This study addressed the behavior of suspended particulate matter (SPM), dissolved inorganic nutrients (DIN, DIP and DSi) and Chlorophyll a (Chl. a) of a small sized river plume derived from the closely lain São Francisco and Guandú river channels, set in the Sepetiba Bay estuary, SE-Brazil. Two surface water sampling campaigns were conducted, one in January 2003 (humid summer conditions) and the other in June 2003 (dry winter conditions). On both occasions, the... |
