| A análise da criação de Farfantepenaeus brasiliensis e Farfantepenaeus paulensis em gaiolas, na Lagoa dos Patos, Rio Grande do Sul (RS), foi realizada a partir de juvenis produzidos em cativeiro com peso médio inicial de aproximadamente 1,2g. O experimento foi realizado em seis gaiolas (três gaiolas/tratamento), com abertura de malha de 5mm, área de fundo de 4m² durante 65 dias. A distribuição dos indivíduos nos tratamentos (F. brasiliensis e F. paulensis) foi aleatória, mantendo-se a densidade de 20 camarões m-2 nas unidades experimentais. A cada 15 dias foram realizadas biometrias para ajuste da quantidade de ração fornecida e avaliação do crescimento dos camarões. Ao final do experimento, foi realizada a biometria total dos camarões para avaliação da... |

| Adenoviruses are among the most promising viral markers of fecal contamination. They are frequently found in the water, sediment and soil of regions impacted by human activity. Studies of the bioaccumulation of enteric viruses in shrimp are scarce. The cities located in the northern coast of the lake systems in Southern Brazil have high urbanization and intensive farming rates, and poor sewage collection and treatment. One hundred (n = 100) Farfantepenaeus paulensis pink-shrimp specimens and 48 water samples were collected from coastal lagoons between June 2012 and May 2013. Water samples were concentrated and the shrimp, mashed. After DNA extraction, samples were analyzed by real time polymerase chain reaction (qPCR) in order to detect and quantify viral... |

| 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 gut content of 495 specimens of Farfantepenaeus brasiliensis, 131 of F. paulensis (Penaeidae) and 102 of Macrobrachium acanthurus (Palaemonidae) were analyzed to establish the composition of their diets F. brasiliensis had as the most important feeding items in its diet larvae of Chironomidae, Polychaeta and Heleobia australis (Mollusca). For F. paulensis, the most important items were the same as for F. brasiliensis, but the order of importance of H. australis and Polychaeta was inverted. M. acanthurus had detritus as the most important item, followed by Chironomidae larvae, Odonata nymphs, and fragments of the macroalgae Chara. The results showed that the three species were omnivorous, with a varied diet including both components of macrofauna of... |

| Three species of shrimp, Farfantepenaeus brasiliensis (Latreille, 1817), F. paulensis (Pérez-Farfante, 1967) (Penaeidae) and Macrobrachium acanthurus (Wiegmann, 1836) (Palaemonidae) were sampled at the Imboassica lagoon (Rio de Janeiro State, Brazil), in order to estimate the overlap of dietary niches and electivity of their prey, through the analysis of the fauna associated with the macroalgae Chara and of the benthic fauna on the sediment. The overlap of dietary niches was estimated using five indexes. A total of 495 F. brasiliensis, 131 F. paulensis and 102 M. acanthurus stomachs were examined. The results of the different indexes of niche overlap exhibited the same general trend in the three species, indicating a high degree of homogeneity in the diet... |

| This paper describes the latest developments on maturation and reproduction of Farfantepenaeus paulensis in captivity, with special reference to the studies conducted during the last decade at the Laboratory of Mariculture, University of Rio Grande in southern Brazil, aiming to improve the future outlook for a sustainable nauplii production of F. paulensis. Particular emphasis has been given on the reproductive cycle, ovarian maturation, maturation and spawning systems, artificial insemination, broodstock reproductive performance and maintenance of captive broodstock. |

| The shrimp Farfantepenaeus paulensis is considered a suitable species for culture in the Patos Lagoon estuary, southern Brazil, where its catch has been decreasing in the last few years. Considering the potential of estuarine areas for shrimp farming, the application of low-cost structures to culture shrimp, such as the pen enclosures, is being proposed as an alternative source of income for artisanal fishermen and farmers living near Patos Lagoon. From an economical standpoint, these alternative systems present several advantages over the traditional pond-based culture systems since land, water pumping and artificial aerations are not required, high natural productivity is available and inexpensive materials are employed in the construction of grow-out... |

| Neste trabalho, foi estudada a possibilidade de cultivar o camarão-rosa Farfantepenaeus paulensis em gaiolas com diferentes densidades de estocagem durante o outono (abril a junho) no estuário da Lagoa dos Patos, RS. Juvenis com peso médio de 4,95g (± 1,69 dp foram estocados em gaiolas nas densidades de 20, 40, 80, 100 e 120 ind/m². Os camarões foram alimentados diariamente ad libitum com pedaços de Corvina (Micropogonias furnieri). As sobrevivências e os pesos foram observados nos tempos 20, 40 e 60 dias de experimento. Durante o período de cultivo a temperatura da água decresceu de 24 para 11°C (média = 17,1°C) e a salinidade oscilou entre 3 e 26 (média = 17,5). As taxas de sobrevivência nas densidades de 20, 40, 80, 100 e 120 ind/m² foram 65%, 68%, 46%,... |
