Última Growth and stress of dourado cultivated in cages at different stocking densities PAB Braun,Neiva; Dafre,Alcir Luiz; Lima,Ronaldo Lima de; Beux,Luis Fernando; Brol,Fernanda Franciele; Nuñer,Alex Pires de Oliveira. The objective of this work was to evaluate the growth and the stress levels of juvenile dourado (Salminus brasiliensis) cultivated in cages. Fish stocked at densities of 15 (D15) and 30 (D30) fish per square meter were evaluated in a completely randomized design with three replicates. Fish were fed twice a day with extruded ration (42% crude protein). Density influenced only biomass and daily food intake, and glucose and lactate concentrations increased over time. D15 and D30 did not influence the growth of dourado. However, the increase of glucose and lactate levels over time indicates that cultivation in cages is a stressful condition for this species.

Em lavoura de arroz irrigado, é utilizada uma grande quantidade de agroquímicos que, dependendo da sua persistência a campo e toxicidade, podem contaminar corpos d’água e afetar organismos vivos. Com o objetivo de determinar o efeito de concentrações de campo dos herbicidas Clomazone, Quinclorac, Metsulfuron-methyl e Propanil na comunidade zooplanctônica (Cladocera, Copepoda e Rotifera), conduziu-se um experimento em viveiros de aqüicultura, de março a maio de 2005, na estação do outono. Nos dias 1°, 2°, 3°, 7°, 10°, 18°, 31° e 51° após a aplicação dos herbicidas, foram coletadas amostras de água para se determinarem parâmetros físico-químicos da água, concentração dos herbicidas e comunidade zooplanctônica. Os parâmetros médios da qualidade da água foram:...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84782008000100002 Phosphorus reduction by sifting fish waste meal Ciência Rural Lima,Ronaldo Lima de; Enke,Dariane Beatriz Schoffen; Braun,Neiva; Fracalossi,Débora Machado. Fish meal is widely included in animal feed because it contains ideal essential amino acids profile, it is rich in energy, essential fatty acids, vitamins and minerals and with >80% apparent protein digestibility in peneid shrimp. In human nutrition, studies are investigating the inclusion of fish meal in snacks, cakes, breads and cookies, as an enrichment in calcium, phosphorus, iron, protein and, especially, omega-3 fatty acids. Omega-3 fatty acids reduces heart diseases and have antithrombotic and anti-inflammatory properties (eicosapentaenoic acid), and are essential to the formation of brain tissue and retina in infants and are important during pregnancy and lactation (docosahexaenoic acid). Fish meal produced from fish waste is rich in minerals... Tipo: Info:eu-repo/semantics/report Palavras-chave: Phosphorus; Fish waste meal; Fractionation; Sieves..

Bras. Zool. Braun,Neiva; Nuñer,Alex Pires de Oliveira. The transportation of live fish is a routine procedure in aquaculture, and includes a series of stressful stimuli such as an increase in the stocking density of specimens per volume of water, and abrupt changes in water quality. This study evaluated the water quality and the stress levels on Pimelodus maculatus (Lacépède, 1803) fingerlings transported in plastic bags by a mechanical transportation simulator. Fish were stocked at densities 4 (22.88 g/L), 8 fish/L (45.76 g/L) and 12 fish/L (68.64 g/L) and the transportation simulation was performed for 4, 8 or 12 hours. A completely randomized experimental design applied to a 3 x 3 factorial model with three replicates was used. Water quality was evaluated by the analysis of the temperature, pH,...

High nitrite (NO2-) levels may develop in aquaculture systems due to high fish density, but studies of lethal concentration values and the effect of NO2- on metabolic parameters and growth are scarce. Consequently, in this study was verified the lethal concentration at 96 h (LC50-96h) for (NO2-) in juvenile silver catfish, Rhamdia quelen and the effect of four waterborne NO2- concentrations (0.06, 0.46, 1.19, and 1.52 mg.L-1) on growth, and hepatic and muscular lactate, glucose, glycogen and protein. Nitrite LC50-96h was 20.46 (confidence interval: 16.10-23.68) mg.L-1. In the growth experiment, exposure to NO2- did not affect weight, length or specific growth rate, but due to mortality (66.7% and 100% after 20 and 40 days, respectively), biomass of...
