1. Use of probiotic-supplemented diet on a Pacific white shrimp farm
ABSTRACT The objective of this study was to evaluate the use of a diet supplemented with Lactobacillus plantarum on performance, immunological parameters, and bacterial microbiota of the digestive tract of white leg shrimp (Litopenaeus vannamei). We used six earthen ponds (1.2 ha) stocked with 14 shrimp m−2 (3 g mean weight). Three ponds received a diet su

2. Nematodes as indicators of shrimp farm impact on an amazonian estuary (Curuçá, Pará, Brazil)
Resumo A carcinocultura reduz a demanda de estoques pesqueiros naturais e evita o dano ambiental resultante da pesca. Entretanto, tem o potencial de afetar a qualidade da água quando não manejada apropriadamente. Nesse trabalho, os impactos de uma fazenda de carcinocultura foram avaliados em um estuário amazônico focando nas mudanças de composição tax

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. Extraction and characterization of lipids from Sarcocornia ambigua meal: a halophyte biomass produced with shrimp farm effluent irrigation
Sarcocornia ambigua é uma planta herbácea perene, nativa da América do Sul e uma nova oleaginosa com potencial para forrageira, cultivada por irrigação direta com água salgada. Suas pequenas sementes se desenvolvem dentro dos segmentos do seu caule cilíndrico sem folhas e, durante a colheita, as sementes se misturam com o material celulósico remanesc

5. Detection of major capsid protein of infectious myonecrosis virus in shrimps using monoclonal antibodies.
Infectious myonecrosis virus (IMNV) has been causing a progressive disease in farm-reared shrimps in Brazil and Indonesia. Immunodiagnosticmethods for IMNVdetection, although reliable, are not employed currently becausemonoclonal antibodies (MAbs) against this virus are not available. In this study, a fragment of the IMNVmajor capsid protein gene, comprising

6. Tratamento de efluentes da carcinicultura por flotação em coluna e flotação
The high productivity in the breeding of shrimp makes it necessary to approach some aspects to their sustainability, particularly the aquatic environment of the nursery. Thus, the treatment of effluents originating from the shrimp becomes of fundamental importance, considering the need to minimize the environmental impacts generated by this productive activi

7. Desenvolvimento de um sistema computacional para geração automática de mapas de vulnerabilidade como ferramenta de auxílio às ações de prevenção ao derramamento de óleo em áreas costeiras
The northern portion of the Rio Grande do Norte State is characterized by intense coastal dynamics affecting areas with ecosystems of moderate to high environmental sensitivity. In this region are installed the main socioeconomic activities of RN State: salt industry, shrimp farm, fruit industry and oil industry. The oil industry suffers the effects of coast

8. Desempenho produtivo do camarão cinza Litopenaeus vannamei, utilizando técnicas de povoamento direto e indireto
The techniques of direct (Pdir) and indirect (Pind) settlement employed in the growthout of marine shrimp Litopenaeus vannamei, were analyzed, in order to determine their efficiency in the productive system of agribusiness. Data of 270 cultures from a commercial shrimp farm located in Rio Grande do Norte, Brazil, were used to relate the variables of manageme

11. A comunidade planctÃnica como indicadora da qualidade da Ãgua em viveiros de cultivo de camarÃes no nordeste do Brasil
A disease of unknown origin is occurring in marine shrimp (Litopenaeus vannamei) ponds causing a decrease in the survival rate of cultured organisms. The disease named Idiopathic Abdominal Necrosis (IAN) have been confirmed in ponds from 14 farms located in PiauÃ, MaranhÃo, Cearà and Rio Grande do Norte states, Northeastern Brazil. In order to contribute

12. Gerenciamento ambiental das fazendas de camarão do Rio Grande do Norte
The present dissertação had as objective to study the ambient management in the Farms Saint Rita, Tahim Agropesca and Agropesca Rigomoleiro, in the Great River of the North. For this we use as theoretical tool some fundantes concepts of geographic science, the space, and as concepts auxiliary of ambient management, of estuaries as the half natural one and
