Aquicultura atual no Semiárido.
Provedor de dados: 14
Autores: CAMPECHE, D. F. B.
Pode parecer contraditório falar de aquicultura nas áreas secas do Nordeste, mas a realidade é que os grandes reservatórios e lagos encontrados na região viabilizam o desenvolvimento atividade de forma sustentável. A constatação dessa viabilidade é que promove o empenho da Embrapa Semiárido na geração de conhecimentos e de tecnologias que impactem a geração de renda e qualidade de vida de piscicultores e pescadores e contribuam para a construção de políticas públicas que ampliem a participação desse segmento na economia regional. A maioria dos piscicultores, principalmente os pequenos, que são em maior número, são ex-pescadores ou filhos de pescadores que acompanharam o declínio da sua principal fonte de renda, à medida que rios, lagos e barragens da...

Biofloc contribution to antioxidant defence status, lipid nutrition and reproductive performance of broodstock of the shrimp Litopenaeus stylirostris: Consequences for the quality of eggs and larvae
Provedor de dados: 5

The aim of this study was to determine biofloc contributions to the antioxidant status and lipid nutrition of broodstock of Litopenaeus stylirostris in relationship with their reproductive performance and the health of larvae produced. Shrimp broodstock reared with Biofloc technology (BFT) compared to Clear water (CW) exhibited a higher health status with (i) a better final survival rate during the reproduction period (52.6% in CW against 79.8% in BFT); (ii) higher glutathione level (GSH) and total antioxidant status (TAS), reduced oxidized/reduced glutathione ratio and a higher spawning rate and frequency as well as higher gonado-somatic index and number of spawned eggs. Finally, larvae from broodstock from BFT exhibited higher survival rates at the Zoe 2...

ABSTRACT The objective of this study was to evaluate the effect of different stocking densities and the presence/absence of two artificial substrates on water quality and production rates of marine shrimp in a biofloc shrimp nursery culture. Two experiments were performed: different stocking densities with mosquito netting substrate and the presence/absence of polyester-type substrate. The first experiment lasted 38 days, and shrimp at an initial weight of 0.013±0.010 g were stocked in 24 tanks. The second experiment lasted 35 days, and shrimp at an initial weight of 0.037±0.002 g were stocked in six tanks. Weekly biometric measurements were performed to adjust the amount of feed. Suspended solids were higher at a density of 6000 PL m−3 and mosquito...
