1. Assessment of the nitrification process in a culture of pacific white shrimp, using artificial substrate and bacterial inoculum in a biofloc technology system (BFT)
RESUMO: Litopenaeus vannamei é o camarão marinho mais cultivado em todos os tipos de sistemas, incluindo o Sistema de Tecnologia de Bioflocos (BFT). Os bioflocos são formados por microorganismos, entre estes, bactérias autotróficas que são responsáveis pelo processo de nitrificação. Este estudo teve como objetivo identificar e promover o desenvolvi

2. Acute toxicity of nitrate in Litopenaeus vannamei juveniles at low salinity levels
RESUMO: Diferentes tecnologias foram desenvolvidas para melhorar o desempenho do Litopenaeus vannamei em baixa salinidade, principalmente em sistemas super intensivos como sistema de recirculação e BFT (Biofloc Technology System). No entanto, há um acúmulo de compostos nitrogenados tóxicos aos camarões, como o nitrato, que em altas concentrações e d

3. Molecular variations in Vibrio alginolyticus and V. harveyi in shrimp-farming systems upon stress
A study was performed to investigate the genomic variations in the shrimp farm isolates of Vibrio alginolyticus and V. harveyi when the isolates were subjected to environmental stress. Samples of shrimps, water and sediment were collected from Southern Indian coastal shrimp farms. Vibrio isolates were biochemically identified and confirmed using 16S rDNA and

4. AvaliaÃÃo do efeito dos polissacarÃdeos sulfatados extraÃdos da microalga Dunaliella tertiolecta como imunoestimulante em juvenis de camarÃo Litopenaeus vannamei / Evaluation of the effect of sulfated polysaccharides extracted from the microalgae Dunaliella tertiolecta as immunostimulant in juvenile shrimp Litopenaeus vannamei
Aquaculture is one of the activities that most expands around the world and microalgae such as shrimps cultures have a great contribution into this progress. The aim of this study was the culture of the marine microlgae Dunaliella tertiolecta and extract its sulfated polysaccharides from the biomass and from the culture medium as well as to evaluate the effe

5. Tempo de residÃncia da Ãgua em um sistema experimental de aquicultura integrada com camarÃes, ostras e macroalgas. / Residence time of water in an experimental integrated aquaculture with shrimp, oysters and seaweeds.
Shrimp culture presented at a world-wide level a significant growth in recent years, mainly in tropical and subtropical regions, however, this expansion comes with diverse environment negative impacts, mainly related to the cultures effluents, which are rich in nitrogen and phosphorous, that are many times discarded in the environment without any previous tr

6. O uso da Dextrose como fonte de carbono no desenvolvimento de bio-flocos e desempenho do camarão-branco (Litopenaeus vannamei) cultivado em sistema sem renovação de água
The objective of the present study was to evaluate the effect of dextrose as carbon source in bio-flocs development, as well as, its contribution to water quality maintenance and performance of Litopenaeus vannamei juveniles reared in superintensive system without water exchange. They were used two treatments, dextrose and molasses, with four replicates each

7. Exploration of genes related to the occurrence of diseases in shrimp Litopenaeus vannamei (Boone, 1931) under conditions of cultivation / Prospecção de genes relacionados à ocorrência de enfermidades no camarão Litopenaeus Vannamei (Boone, 1931) sob condições de cultivo
The marine shrimp culture has achieved great importance in the global economy as an agriculture business, not only for jobs and income generation, but especially because it represents a viable alternative source of animal protein for the growing global food demand. However, the occurrence of diseases in shrimp culture, especially those of viral aetiology, ha

8. Influência das baixas salinidades na composição microbiana e no desempenho de Juvenis de Litopenaeus vannamei cultivados em sistema super-intensivo sem Renovação de Água
Considered environmentally friendly, due to minimal water use and effluents emission, the production systems performed without water exchange present the additional advantages of the possibility of rearing marine shrimp far from the valued coastal zone and close to consumption centers, as well as supplementation of the animals diet through their characterist

9. Environmental management strategy based on principles of cleaner production: a case study in shrimps culture farm / Estratégia de gestão ambiental baseada nos princípios da produção mais limpa : um estudo de caso focado no segmento da carcinicultura
O objetivo do trabalho é apresentar uma estratégia de implementação da produção mais limpa (P+L) em uma fazenda de cultivo de camarões. A metodologia utilizada foi pesquisa exploratória, realizada pela investigação via estudo de caso, implementada em uma unidade produtiva localizada no nordeste do Brasil. O trabalho aborda desde aspectos genéricos

10. 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

11. Estudo comparativo de dois tipos de cultivo: monocultivo (camarões) versus cultivo integrado (algas/camarões)
The integrated culture of seaweed and aquatic animals is an ancient practice in Asian countries. The expansion of this practice to western countries is consequence of the recognition of this system as a sustainable alternative that allows economical diversification and mitigation of environmental impacts generated by effluents of aquaculture. This study eval

12. CRIAÇÃO DO CAMARÃO-ROSA Farfantepenaeus brasiliensis (CRUSTACEA: DECAPODA) EM GAIOLAS NO ESTUÁRIO DA LAGOA DOS PATOS, RS.
The cage culture of Farfantepenaeus brasiliensis and Farfantepenaeus paulensis was analyzed in the Patos Lagoon estuary using juveniles produced in captivity. Mean initial weight of the juveniles was approximately 1.15g. The experiment was conducted in 6 cages (3 per treatment), with mesh size of 5mm and bottom area of 4m2 , during 65 days. The individuals w
