ABSTRACT Cynoscion leiarchus (Cuvier, 1830) is a coastal fish species that is widely distributed along the Western Atlantic coast, from Belize to Southern Brazil. In Brazil, C. leiarchus It is an important resource for commercial and artisanal fisheries. Our objective was to describe the oogenesis and spermatogenesis stages of the species and to estimate batch size and relative fecundity of a population at a tropical bay in southeastern Brazil. The examined specimens were obtained from artisanal catches that took place from July 2013 to June 2014. A total of 18 individuals (11 females and 7 males) were examined for histological analysis and 20 spawning-capable females were used to estimate fecundity. Five stages of oocyte development (primary growth,...

The silverside, Atherinella brasiliensis (Quoy &amp;amp; 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...

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...

The length-weight relationship of populations of white croaker Micropogonias furnieri (Desmarest, 1823) in the Sepetiba Bay (22º54'-23º04'S; 43º34'-44º10'W), were assessed. It aims to contribute to the knowledge of the biometrics and to estimate the biomass of this very abundant fishery resource in the Bay. Fishes sampled, in both trawling beach seine, sampling programme, from October 1998 to May 1999 were analyzed. The equation found was W = 0.00000942 L2.99 fom the natural logaritmized transformation of the raw data, through ordinary least square equation = In W = -11.57 + 2.996 In L (r=0.99). The condition factor was relatively high compared with coastal population from Southeast Brazil, probably due to in this study both males and females from juvenile...

Autores: Nicolau,Cristiane Ferreira; Oshiro,Lídia Miyako Yoshii.
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 objective of this work was to get some knowledge about the Guaia stone crab reproduction. The sampling was monthly obtained in the intertidal zone at the Ibicuí Rock Beach. The 638 crabs were collected from August, 1995 to March, 1997. In this total amount 293 were males and 345 (41 ovigerous crabs) were female crabs. Biometrical data informing the total width and length were taken, and gonadal stage was checked macroscopically. The total male width range was between 7.9 to 67.1 mm, while in the female crabs it was between 4.4 to 79.3 mm. The female ones were bigger than the male ones. The ovigerous female crabs were found mainly on Spring and Summer and it probably indicates the reproduction season. The carapace width range of the ovigerous female...

The white croaker Micropogonias fumieri (Desmarest, 1823) is one of the most abundant fish species in the Sepetiba Bay, being heavily exploited in fisheries. Two hundred eleven fishes, captured from October 1998 to September 1999, in monthly samplings with otter trawling, were studied. The aim here is to characterize morphometrics of populations that use de Bay in order to compare with other areas. Measurements included standard length (SL), head length (HL), Pre-dorsal distance (PDD), pectoral distance (PD), ventral distance (VD) and anal distance (AD), pectoral length (PL) and eye diarneter (ED). The values of HL, PDD, PD, VD, AD, were related to SL, while ED was related to HL. Scatterplot from logaritrnized data, by sex, were analyzed in order to assess...

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 &gt; 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...

Autores: CARVALHO,CÁSSIA DE; KEUNECKE,KARINA A.; LAVRADO,HELENA P.
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...

Autores: Rodrigues,Raphael Paiva; Knoppers,Bastiaan Adriaan; Souza,Weber Friederichs Landim de; Santos,Elisamara Sabadini.
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...

Zinc detoxification by a cyanobacterium from a metal contaminated bay in Brazil
Provedor de dados: 52
Autores: Andrade,Luciana; Keim,Carolina N.; Farina,Marcos; Pfeiffer,Wolfgang C.
We describe here the trapping of zinc in polyphosphate granules of the cyanobacterium Synechocystis aquatilis NPBS-3. Cells were cultured in 25 µM of zinc chloride and prepared for electron microscopy and energy-dispersive X-ray analysis. Some ultrastructural features were changed by zinc exposure, the increase of glycogen granules number being the main change. The polyphosphate granules contained phosphorus, sulphur, calcium, iron and zinc. The trapping of zinc in polyphosphate granules seemed to be an effective way of detoxifying the metal and surviving in the bay. As a non-specific mechanism, these polyphosphate granules could also be effective in trapping other metals in excess.
