Technical paper on Toxicity Equivalency Factors for Marine Biotoxins Associated with Bivalve Molluscs
Provedor de dados: 5
Autores: FAO/WHO.
World bivalve molluscs production (capture + aquaculture) has been increasing substantially in the last fifty years, going from nearly one million tonnes in 1950 to about 15 million tonnes in 2012. Being filter feeders, bivalves utilise natural plankton and detritus as feed and do not require artificial feeds. But this filter feeding nature is also the reason for the requirement of strict environmental hygiene to produce bivalves safe for human consumption. They tend to concentrate microorganisms, toxins and chemicals from the environment and therefore, their safety management requires stringent sanitary measures to ensure consumer protection. Following the request of Codex Committee on Fish and Fishery Products (CCFFP), FAO/WHO agreed to develop a...

Autores: Priour, Daniel.
The quick evolution of fish farming in Europe, and its development towards the open sea needs suitable farming tools. These tools must withstand the difficult sea states, but they must be easy to use, well adapted to the fish farming and not too much expensive. This book helps the design of such tools. It defines the solicitations of the sea on all the structures, and presents rules and methods to control these solicitations. Here, a structure is composed of a rearing support, a mooring system and equipments. This book describes these components, class them and gives lists of providers. The rearing support can be a cage, a group of cages or a boat. The support can float or to be submersible. The mooring system can be made up ropes, chains, anchors,...

L’approche écosystèmique et la gestion par bassin versant: le cas de la Somone
Provedor de dados: 20
Autores: Diop, M.; Konaté, M.
L’eau est l’un des éléments de base de tous les écosystèmes. En fonction du milieu où elles s’écoulent, les ressources hydriques sont plus ou moins importantes, accessibles ou vulnérables. Les caractéristiques de l’eau sont dépendantes du milieu biophysique environnant, mais elles peuvent être fortement modifiées par la présence humaine. En effet, l’eau est une composante fondamentale des activités humaines, que ce soit pour l’alimentation, la production de biens, le commerce ou les loisirs. Ces activités exercent une pression sur les écosystèmes naturels. Elles modifient la ressource hydrique sur le plan quantitatif et qualitatif, entraînant des répercussions plus ou moins importantes sur les écosystèmes touchés et, par conséquent, sur les espèces...

Autores: LIMA,PEDRO C.; DUTRA,IVERALDO S.; ARAÚJO,FRANCISCO A.A.; LUSTOSA,RICARDO; ZEPPELINI,CAIO G.; FRANKE,CARLOS R.
Abstract  In 2008, 270 wild birds from aquatic environments were found dead or debilitated on the banks of smaller lakes that had been formed due to the decrease in the level of the holding lake of the Sobradinho Dam located on the São Francisco River in the Caatinga of Bahia, Brazil. The outbreak occurred months after the dam’s partial drainage, with the formation of puddles that accumulated decomposing organic material. Amongst the 270 individuals examined and/or found dead, the majority (50%) of the birds found belonged to the Anatidae family. The debilitated birds presented neurological clinical signs including lack of motor coordination, weakness, grave flaccid paralysis in the legs, wings, neck and eyelids, diarrhea, and dyspnea. Tissue samples of...

Antimicrobial susceptibility, hemolysis, and hemagglutination among Aeromonas spp. isolated from water of a bovine abattoir
Provedor de dados: 58
Autores: Bizani,Delmar; Brandelli,Adriano.
The presence of Aeromonas spp. in food has been demonstrated. They are often introduced from water, which is the natural habitat of many species and is thought to be the main source of contamination. The occurrence of Aeromonas spp. was investigated in 70 water samples of a bovine abattoir. Aeromonas spp. were present in 21.4% of water samples. A. hydrophila was isolated from 11.4% of supplying water samples and from 25.7% of the water drained from carcasses, whereas A. sobria was sole isolated from 5.7% of supplying water samples. Although greater number of positive samples were from water drained from carcasses, only A. hydrophila isolates were present. This suggests that the supplying water is the source of contamination. The antibiotic susceptibility...

Abstract Rivers and streams are important reservoirs of freshwater for human consumption. These ecosystems are threatened by increasing urbanization, because raw sewage discharged into them alters their nutrient content and may affect the composition of their microbial community. In the present study, we investigate the taxonomic and functional profile of the microbial community in an urban lotic environment. Samples of running water were collected at two points in the São Pedro stream: an upstream preserved and non-urbanized area, and a polluted urbanized area with discharged sewage. The metagenomic DNA was sequenced by pyrosequencing. Differences were observed in the community composition at the two sites. The non-urbanized area was overrepresented by...

ABSTRACT: The investigation of the presence of antibiotic-resistance genes in aquatic environments is important to identify possible reservoirs of resistant microorganisms that could be a threat to human and animal health. The aims of this study were to analyze the presence of genes conferring resistance to antimicrobials in the aquatic environment and to assess the quality of water in zoo lakes. Results showed a pattern of genes conferring resistance to multiple antibiotics and turbidity, which was expected to be due to the presence of contaminants. The most frequent genes were sul I and sul II (sulfonamides), which were present in all the lakes, followed by genes encoding β-lactamases such as blaPSE I (77.8%) and ampC (66.7%). However, tet(K), tet(M),...
