| Chloroscombrus chrysurus (Linnaeus, 1766) is the most abundant representant of the Carangidae family in the Sepetiba bay, a c.a. 450 km² semi-closed coastal area in the Southeastern Brazil. We analyze fish (number, weight and size) and environmental data to assess the part of life history of this species in tropical embayment environments. Fish sampling were taken in triplicates by monthly bottom trawls, in three bay zones (inner, middle and outer), defined according to a spatial gradient of depth and salinity. Juveniles were firstly caught in the inner bay zone measuring 30-90 mm total length - TL (mode = 60 mm TL) in Spring. Then they move toward the middle and outermost part of the bay in Summer-Autumn (120-180 mm TL), following a seaward migration to... |

| The ichthyofauna composition of the Baía da Ribeira was analyzed between December 1998 and November2001. The instruments used were an otter-trawl net, beach seines, cast net and visual census. It was registered two classes, composed by 16 orders, 59 families and 148 species. The high wealth of the region is due to the great diversity of environments and its location at the north limit of Argentine an Zoogeographic Province. The instruments diversification, the samples regions and the long sampling period were the responsables to the great numbers of collected species in comparison to some others studies at the same area. |

| ABSTRACT This study aimed to investigate for the first time the ecological interactions between species of Agaricomycetes and their host plants in Brazilian mangroves. Thirty-two field trips were undertaken to four mangroves in the state of Pernambuco, Brazil, from April 2009 to March 2010. One 250 x 40 m stand was delimited in each mangrove and six categories of substrates were artificially established: living Avicennia schaueriana (LA), dead A. schaueriana (DA), living Rhizophora mangle (LR), dead R. mangle (DR), living Laguncularia racemosa (LL) and dead L. racemosa (DL). Thirty-three species of Agaricomycetes were collected, 13 of which had more than five reports and so were used in statistical analyses. Twelve species showed significant values for... |

| ABSTRACT Detection of virulent strains associated with aquatic environment is a current concern for the management and control of human and animal health. Thus, Vibrio diversity was investigated in four estuaries from state of Ceará (Pacoti, Choró, Pirangi and Jaguaribe) followed by antimicrobial susceptibility to different antimicrobials used in aquaculture and detection of main virulence factors to human health. Isolation and identification were performed on TCBS agar (selective medium) and dichotomous key based on biochemical characteristics, respectively. Nineteen strains of genus Vibrio were catalogued. Vibrio parahaemolyticus (Choró River) and V. alginolyticus (Pacoti River) were the most abundant species in the four estuaries. All strains were... |

| ABSTRACT The increase in production, consumption and inadequate disposition of plastics has generated an accumulation of these elements in marine ecosystems, which have become important microplastics sinks (< 5 mm). The objective of this research was to determine the temporal and spatial differences in the density, distribution, and type of microplastics in the sediments of Buenaventura Bay. For this purpose, sediment samples were collected in the internal estuary (close to the rivers) and in the external estuary (with a greater marine influence). Samples were obtained in the dry, transition, and rainy season for the years 2015 and 2019. Microplastics were extracted by density separation method, each particle was classified and measured by optical... |

| Several coastal fish use the estuarine habitat during a part of their life cycle. These sites are considered good for the reproductive activity, as well as for the growth of larvae and juveniles. Concerning the Gerreidae, however, many studies reveal that most species leave the estuaries to reproduce at sea. At Guaratuba Bay, southern Brazil, this family is represented by three genera and five species, which make an important fraction of the local assemblage. The present study investigated the populational structure and breeding habits of three Eucinostomus species, in order to know what relationship exists between them and the mangrove. It was found that the Guaratuba mangrove represents a transitory habitat for the life cycle of the Eucinostomus species.... |
