1. Analysis of the chemical properties of salted cobia (Rachycentron canadum)
Abstract Aquaculture of cobia (Rachycentron canadum) is still incipient in Brazil, as well as the sale of its meat. However, there is a market demand for this product in the state of Rio de Janeiro. The salting process for the meat of cultivated cobia is a way of preserving and marketing the product for the growers. Thus, the present study aimed to assess th

2. Zooplankton associated with phytotelms and treefrogs in a neotropical forest
RESUMO Hipóteses sobre a distribuição das comunidades de zooplâncton em vários ecossistemas são muitas vezes limitadas pela falta de dados sobre os seus mecanismos de dispersão. Muitas pesquisas sobre a dispersão passiva mediada por anuros têm sido desenvolvidas em bromélias, porém com foco em ostrácodes e anelídeos. Nós investigamos o potencia

3. Biosseguridade para sistemas de produção de peixes em tanque-rede em função da colmatação agravada por Limnoperna fortunei
RESUMO Este trabalho avaliou a colmatação por Limnoperna fortunei em diferentes materiais para confecção de telas de arame, a dinâmica da colmatação pelo molusco e a relação custo-benefício dos materiais usados em tanques-rede. Utilizaram-se amostras de telas de simples torção de malha 19mm, de cinco tipos diferentes de revestimentos, colocadas n

4. Anoxia stress and effect on flesh quality and gene expression of tilapia
Abstract We evaluated the effect of the length of stay out of water on stress, gene expression, pH variation, blood parameters, histological analysis and water holding capacity (WHC) in fillets of the Nile tilapia (Oreochromis niloticus) cultivated in net-tanks. For this purpose, the fishes were maintained out of water under different periods of anoxia. Thr

5. Contribuição metodológica para a pré-identificação de áreas adequadas à implantação de parques aquícolas no Reservatório de Nova Ponte - Minas Gerais / Methodological contribution for the delimitation of fish farms in tanks in the Reservoir of Nova Ponte - Minas Gerais
The purpose of this thesis is to propose a methodology for the delimitation of fish farms in tanks. The proposed methodology was applied in the reservoir of Nova Ponte - MG, with the cultivation in net cages of the Red-tailed Lambari (Astyanax fasciatus), Piracanjuba (Brycon orbygnianus) and Tilapia (Tilapia sp.) species, using GIS. It was surveyed the facto

6. Produtividade Primária do Biofilme em Cultivos dos Camarões Marinhos Farfantepenaeus paulensis e Litopenaeus vannamei.
The primary production of biolm, or periphyton (a microorganisms community attached to submerged natural or artificial substrates) has been used for a long time as a strategy to improve the water quality and as a complementary food source for raised organisms. In spite of the importance of natural productivity in aquaculture systems less atention is given to

7. Utilização de substrato artificial em cultivo do camarão Litopenaeus vannamei, em água oligohalina e meio heterotrófico.
The use of artificial substrates in aquaculture has been used to provide the increase of culture area and natural food, improving the water quality of shrimp performance. In order to maximize the survival, feed conversion and final weight of marine shrimp Litopenaeus vannamei, cultured in oligohaline water (>0.5) and in heterotrophic system, were evaluated t

8. Suplementação de metionina e/ou lisina em rações com níveis decrescentes dos teores de proteína para juvenis de tambaqui, Colossoma macropomum
The aim of this study was to evaluate the effects of the reduction crude protein level (CP), and lysine and methionine supplementation on fish performance and total ammonia nitrogen excretion in tambaqui juveniles ( ). Three hundred and thirty six fish (64,5 1,06g) were uniformly distributed in 24 tanks (120 L), and in a complete randomized design with two l

9. Sustentabilidade ambiental do cultivo intensivo de Tilápias (Oreochromis niloticus) em tanques-rede e a capacidade de suporte de quatro reservatórios em uma região semi-árida tropical
Intensive production of tilápias, in cages or net tanks, has been proposed as an alternative to increase fish production, that would generate income and offer animal protein in different tropical and subtropical countries. However, this system of production enriches the aquatic environment with nutrients, principally nitrogen and phosphor derived from the d

10. Monitoramento de aves limícolas na Salina Diamante Branco, Galinhos, Rio Grande do Norte, Brasil
Monitoring of the shorebirds of the Diamanle Branco saline located at the municipality of Galinhos, in the coast of the State of Rio Grande do Norte, was initiated in 1998, with qualitative surveys, bird traps using mist net, captured and banding and field observations on the diet of some species. Parameters such as constancy were verified, specific diversit
