| Abstract Middens are archaeological sites dating between 8,000 and 1,000 years before present and are commonly found on the Brazilian coast. Data were collected from 68 middens allowing an inventory of 142 fish species, most of them recorded in no more than five sites. Conversely, Micropogonias furnieri and Pogonias cromis had the highest frequencies of occurrence. The biogeographic, ecological and economic data showed that most of the identified fish are widely distributed in the Western Atlantic (59.72%) and inhabit estuarine environments (53.99%), while most species have a demersal habit (35.92%) and exhibit oceanic migratory behaviour (28.87%). Lastly, the surveyed fish are predominantly carnivorous (72.54%) with some commercial value (96.48%).... |

| The córrego Paulicéia is a direct tributary of the rio Mogi-Guaçu, located in Santa Rita do Passa Quatro, State of São Paulo, Southeastern Brazil. This stream runs inside a savannah-like (cerrado) environment and it associated vegetation. Biological and ecomorphological aspects of its fish community were studied in three stretches of the stream, denominated herein as the upper, middle and lower courses. The fish fauna recorded in this study consisted of 15 species, belonging to five orders and nine families, based in a total of 715 collected individuals representing 1,450 kg of biomass. The most important abiotic factors related to the occurrence and distribution of the fish fauna were the substrate, current speed, and presence or absence of riparian... |

| Small-scale fisheries have a great socioeconomic importance in Brazil. Different regional characteristics along the coast, mostly related to landing sites, equipment used, and targeted species, renders its assessment and monitoring difficult. The aim of this paper is to present a list of species of bony fishes (Teleostei) caught by artisanal fisheries along the São Paulo coast, southeastern Brazil and to provide comments on the relative abundance and conservation status of those species. A total of 315 fishing fleet landings were surveyed, and 106 species distributed among 38 families were recorded. Sciaenidae and Carangidae were the most frequent families in species number. The southern king weakfish, Macrodon atricauda, was the most abundant species,... |

| Abstract: Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012. The ichthyofauna consisted of 245 species (81 families, 32 orders and 2 classes). Among the species, 50 species were... |

| A comparative study was conducted in two zones of the Northern Province of New Caledonia, one located windward (east coast) and the other located leeward (west coast). In each zone, three major sectors were investigated: fringing reefs close to areas of important mining activities, fringing reefs close to areas of moderate mining activities, and fringing reefs close to areas free of mining activities. In addition, on the west coast, fringing reefs close to areas of high natural ground erosion were also studied. Only commercial fish species sensus late were censused on a total of 163 stations, concerning 165 fish species. Substrate characteristics were not different between zones and sectors. However, significant differences were observed for living... |

| 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. |

| Fish assemblages are an important element of sandy beaches, as they are fundamental for these ecosystems' balance of energy. Descriptions of the structure of fish assemblages in the sandy beaches of northeastern Brazil are scarce; this is especially true for the state of Rio Grande do Norte, which northern coast is poorly studied. This study aimed to identify the fish fauna of São Cristóvão Beach and to determine their assemblage structure. Three trawlings, considered as replicates, were undertaken monthly, in the same day, during 10 minutes each time, parallel to the coastal line, and in the direction of current, from February 2010 to January 2011. To describe the general pattern of the fish assemblage, the abundance, frequency and trophic categories of... |

| Little is known about the ichthyofauna of the São Tomé and Príncipe archipelago. Since the early works of Osório, at the turn of the century, only few attempts were made to update and complete existing knowledge on fish systematics and biodiversity from this area. Over the past few years, however, several surveys made it possible to start an inventory of the coastal fishes for the archipelago. These are mainly based on specimens that where captured or observed whilst diving and also on fishes landed on beaches by local artisanal fishermen. A total of 124 species belonging to 108 genera and 61 families was identified. Some specimens, including Serranidae, Gobiidae and Labridae probably belong to undescribed species and are currently being studied. |

| ABSTRACT When a river is dammed, impacts differ according to distance from the dam under consideration, and sites closer to the dam are more affected than distant ones. Damming a river changes the flow and landscape characteristics, which, in turn, change the hydrological, limnological and ecological dynamics, such as biological production, species distribution, and ecosystem structuring, functioning and services. This study evaluates the distribution pattern of the Siluriformes (catfish) fish species near a small hydroelectric power plant in the Jaguariaíva River, considering three distinct distances from the dam: upstream region, reservoir and downstream region. Samples were taken with gillnets between March 2013 and December 2014. The abundance and... |

| A survey of the tidal pool fish community was carried out between february/1987 and january/1988, at Cabo Branco Beach, João Pessoa, Paraíba, Brazil. Specimens were collected monthly at low tide, using rotenone. A total of 3143 specimens was obtained. The most speciose families were Ophichthidae (14% of the total number of species), Mugilidae (11%) and Muraenidae (9%), and the most representative ones in number of individuais were Gobiidae (48%), Pomacentridae (13%) and Labrisomidae (10%). The main resident species were Bathygobius soporator (Valenciennes, 1837) and Abudefduf saxalilis (Linnaeus, 1758). The presence of a large number of juveniles in the pools indicated the importance of the studied sites as nursery áreas for several fish species. |

| A survey of the tidal pool fish community was carried out between April 1998 and May 1999, at the beaches of Praia Vermelha (PV) and São Roque (SR), Santa Catarina, Brazil. The pool of PV was bigger and closer to the subtidal. Specimens were collected monthly at low tide, using quinaldine. In PV we collected 1287 fish belonging to 19 species and in SR 553 fish were caught corresponding to 11 species. In both pools, dominant species were Bathygobius soporator (Gobiidae), Abudefduf saxatilis (Pomacentridae), Parablennius pilicornis (Blenniidae), Gobiesox barbatulus (Gobiesocidae), Labrisomus nuchipinnis (Labrisomidae) and Epinephelus marginatus (Serranidae). Summer months had higher abundance and diversity values, and correspond to a recruitment season for... |

| Ecological studies were conducted in the ichthyofauna of Cedro, a small headwater stream located in a degraded area of State of São Paulo, Brazil, situated in the upper Paraná River basin. These are the results of two non-consecutive years observations and collections in two biotopes of that stream: a pool and a rapid. The ecological characteristics studied change in space and time. The present richness of species is high (21 species), nine of which are constant, six accessory and six accidental. The diversity is low (0.69 to 2.38), and the numeric predominance, from one to three species, occurred in both biotopes. The most frequent species are Poecilia reticulata (Peters, 1859) (28.1%), Corydoras cf. aeneus (Gill, 1858) (20.3%) and Hypostomus cf.... |
