| Uma revisão do sistema de coagulação sanguínea de peixes. Hemostasia é uma função de grande importância para responder a danos e desordens da coagulação sanguínea. Assim, é fundamental para prevenir hemorragia e perda de sangue após um dano vascular, pois o corpo necessita de um mecanismo de coagulação eficiente. Em peixes, apesar de existirem diversos estudos sobre fatores intrínsecos e extrínsecos, algumas questões significantes sobre a regulação do sistema de coagulação permanecem em aberto, uma vez que estes dados estão dispersos na literatura. Esta revisão compara e discute os diversos aspectos dos mecanismos de coagulação em peixes teleósteos, incluindo algumas substâncias relacionadas a este processo, fatores envolvidos na hemostasia, as implicações... |

| The aim of this study was to investigate monogenean fauna in gills of Geophagus camopiensis, Pterophyllum scalare, Satanoperca jurupari,and Satanoperca acuticeps in a tributary from the Amazon River system in Brazil. A total of 2,148 monogenean specimens were collected from140 fish examined from March 2012 to March 2013, and 84.3% of these fish were parasitized by 1 or more species. Such monogeneans were:Sciadicleithrum geophagi, Sciadicleithrum juruparii, Gussevia spiralocirra and Gyrodactylus sp. However, only G. camopiensis was parasitizedby more than 1 species of monogenean, while S. jurupari and S. acuticeps were parasitized by the same species. Prevalence, mean intensity andmean abundance varied among host species and the highest levels of infection... |

| Parasitic and infectious diseases are common in finfish, but are difficult to accurately estimate the economic impacts on the production in a country with large dimensions like Brazil. The aim of this study was to estimate the costs caused by economic losses of finfish due to mortality by diseases in Brazil. A model for estimating the costs related to parasitic and bacterial diseases in farmed fish and an estimative of these economic impacts are presented. We used official data of production and mortality of finfish for rough estimation of economic losses. The losses herein presented are related to direct and indirect economic costs for freshwater farmed fish, which were estimated in US$ 84 million per year. Finally, it was possible to establish by the... |

| The purpuse of this study was to investigated the influence of anthropogenic impacts on Podocnemis unifilis nesting on a stretch from Falsino river, with two forest reserves, and one urban area on the Araguari river, state of Amapá, eastern Amazon (Brazil). A total of 180 nests were found, being 89.4 % in the forest reserves and only 10.6 % in urban areas. On Falsino river, we observed a spawning pattern, because the number of nests was correlated to the length and width of the nesting locations. On Araguari river, the P. unifilis nests were generally found in areas with surrounding vegetation up to 5 meters in height, minimum distance of 120 meters from residences and immediately or after places of higher exploration of pebbles. Females from Falsino river... |

| Immunostimulants in farmed fish diets has been considered an effective approach to health management. This study aimed to assess antioxidant effects and resistance against pathogens of Colossoma macropomum (tambaqui) fed essential oil (EO) of M. piperita at 0%, 0.5%, 1.0% and 1.5% kg−1 commercial feed during 30 days. Tambaqui were challenged with Aeromonas hydrophila and did not present clinical signs of alterations. Higher hepatic catalase activity was observed in fish fed 1.0% of M. piperita EO, compared with 1.5%. Renal superoxide dismutase and glutathione peroxidase decreased in the fish fed M. piperita EO. Hepatic and renal lipid hydroperoxide increased among fish fed diets with 1.0 and 1.5% of EO. Tambaqui fed 1.0% of M. piperita EO showed... |

| Parasitos são considerados componentes relevantes da biodiversidade e contribuem para o conhecimento de seus hospedeiros e na preservação de ecossistemas. A finalidade deste estudo foi analisar a infestação por Argulus sp. e Ergasilus turucuyus em Trachelyopterus coriaceus, do Rio Pedreira. Foram capturados peixes-hospedeiros em seis pontos amostrais distintos, no período de dezembro/2015 a dezembro/2016. A pesca foi realizada com malhadeiras (20 a 60mm entre nós), com 24 horas de permanência na água e vistoriadas a cada quatro horas. De cada peixe coletado, foi mensurado o Comprimento Total (Ct) e o Peso total (Pt). Por meio da celiotomia, identificou-se o sexo dos indivíduos. Os ectoparasitos foram obtidos através da inspeção de boca, narinas e brânquias... |
