14. Desenvolvimento de Método Rápido de Análise de Histamina por Cromatografia Líquida de Alta Eficiência em Atum. / Development of Quick Method for Analysis of Histamine in Tuna by High Performance Liquid Chromatography.
Histamine is an important biogenic amine found in fish like tuna, mackerel, bonito and sardines, and in fermented foods like cheese, salami and sauerkraut. Its presence in food should not exceed certain limits, because the intake of this substance in quantities that vary from person to person, can cause scombroid poisoning, whose main symptoms are: abdominal

16. Caracterização dos quimiorreceptores de O2 envolvidos no controle dos reflexos cardio-respiratórios de trairão, Hoplias lacerdae (Teleostei, Erythrinidae) em resposta à hipóxia ambiental
The ability to sense and respond to oxygen availability in the environment is of extreme functional importance for fish. This is even more so in tropical freshwater habitats where environmental hypoxia can occur rapidly in space and time. Recent physiological studies on the cardio-respiratory response of tropical fishes have focused on hypoxia tolerant speci

17. Exigências em proteína e energia e valor biológico de alimentos para o dourado Salminus brasiliensis / Protein and energy requirements and biological value of selected feedstuffs for the dourado Salminus brasiliensis
The dourado, Salminus brasiliensis, presents excellent farming characteristics, such as fast growth and excellent flesh quality. However, the lack of the knowledge on the species nutritional requirements and biological value of feedstuffs hamper the formulation of diets for optimized performance and, consequently, the speciesintensive farming. To determine d

18. Efeitos da adição de aminoácidos essenciais livres à dieta e da ausência de nutrientes na atividade de enzimas digestivas e no metabolismo intermediário de juvenis de matrinxã (Brycon amazonicus).
For the nutrients ingested by fish are used for growth and maintenance of the energetical metabolism, they need firstly being absorbed by gastrointestinal tract. However, the most foods ingested cannot be absorbed directly through the gastrointestinal mucosa, since they are largely formed by high molecular weight molecules. The process of transforming large

19. Impacto da piscicultura sobre bacias hidrográficas de pequeno porte
The fast aquiculture expansion demands an assessment of the environment quality considering the impacts occurred on the water resources. Due to the importance of the fish farming activity in the Assis city of SP state, and the appropriate handling of the natural resources, this study intended to monitor the sub-basins of the Queixada and Macuco rivers to eva

20. A comunidade de peixes dos reservatórios dos trechos médio e baixo rio Tietê, com ênfase nas espécies Plagioscion squamosissimus e Geophagus surinamensis. / Fish community of the reservoirs located on middle and low Tietê River, with emphasis in the introduced species Plagioscion squamosissimus and Geophagus surinamensis.
From sixties, the fish species introduction has been being a constant event in the reservoir system located on middle and low Tietê River - SP, which resulted the success introduction of Plagiosicon squamosissimus and Cichla cf. ocellaris in all these reservoirs. According to this context, the present work objectified characterize the fish community, with f

23. Strategies to alleviate the incidence of ascites in broilers: a review
Ascites is a complex problem caused by many interacting factors such as genetics, environment and management. Many nutritional, medicinal and management strategies have been proposed to alleviate the problem. Higher levels of dietary vitamin C and E along with selenium yeast might be beneficial, presumably because of their role in improving cellular integrit

24. Avaliação de densidades de estocagem de alevinos da tilápia Oreochromis niloticus (linhagem Chitralada) cultivado em gaiolas.
Cage tilapia culture in Northeast region had grown very fast in the last years, where the climate provides adequate culture conditions during all the year. This kind of culture normally is developed in two culture phases: fingerlings or nursery phase and growout phase. Both of them need improvements in the management techniques and in the stocking densities,
