ln the Pertuis charentais shallow area, located between the mainland and the Ré and Oléron islands, marin space is in dispute between the severals stakeholders. The fishing in this area is permitted by a licencing policy and is strongly affected by the space competition. lts future is also uncertain because of the state of the fishing stocks, the new regulations which must be implemented. Given this context, this study aims to assess the evolution and adaptation abilities of the exploitation system in the Pertuis charentais facing the change of the socio-technic context. On board and at port, surveys were carried out. The fishing fleet is made up of old boats, but the fishing is attractive for the fishermen. The enterprise logic functioning as studied and... |

En la III y IV Regiones las áreas de manejo y explotación de recursos bentónicos (AMERB) se han establecido como la principal herramienta de manejo del recurso loco (Concholepas concholepas). Sin embargo, su aplicabilidad para la administración y aporte en términos del desarrollo sustentable, aunque sugerentes, requieren de una evaluación objetiva, en cuanto al manejo de carácter discreto que se ha establecido para cada AMERB, desconociendo la eventual interacción espacial de las mismas. En este marco, se desarrolla una aproximación para evaluar el desempeño de las AMERBs desde una perspectiva integral bajo un enfoque metapoblacional. Si bien el estudio está orientado a proporcionar la información de campo que permita probar la hipótesis de metapoblaciones... |

The slipper-limpet (Crepidula fornicata) is a marine gastropod which causes serious perturbations in shellfish beds, because of spatial spreading and density rising. Along French coasts, in Northern Brittany, two bays are highly colonized : bay of Saint-Brieuc, centre for scallops fishery, and bay of Mont-Saint-Michel, a famous oyster-farming area, with a total limpet stock about 450 000 metric tons. The association AREVAL was founded in 2001 to manage there, an industrial collect of limpets by a succing-dredge, followed ashore by a treatment for calcareous soil improvement. The scientific survey, contracted to IFREMER, included measurements of long andshort-term dredge's effects on grounds and limpet population, and proposals to set up dredging... |

The objective of this study was to develop an effective biological sampling programme for fish species in the English Channel (ICES Divisions Vild and Vile) which are not subject to quota management, and to prepare these data for use in multispecies, multi-fleet models being developed by the Channel Fisheries Study Group. Length and age data were coIlected for six non-quota species, and length data for a further five species. The samples were coIlected over a period of two years from important ports on the French and UK coasts. The exploitation patterns of each species were described by allocating catches from similar catching gears, regions, seasons and target species into common units referred to as métiers. The most important métiers in terms of landed... |

The aim of this work, which was done as a Doctorate of Philosophy (Phd), was to collect the information necessary to help improve the management of the western Channel spider crab stock. The fîrst section présents the main aspects of spider crab population biology. As well as contributing our own results on spider crab habitat, stock density, démographie structure, growth and mortality estimâtes, migrations, reproduction and recruitment, a synthesis is included of the existing scientific literature. The second section on exploitation covers various features of the fishery : its history, fishing methods, fleet structure, spatial and seasonal distribution of fishing efforts in 1986, trends in the landings, fishing effort and catch per unit effort,... |

Abstract This study aimed to carry out a diagnosis of the cheese whey exploitation by the Brazilian dairy industry using a questionnaire survey. The dairy industries (n=100) were mainly from Southeast (55%) and South (25%) regions and supervised by the Federal Inspection System (80%). Most of them produced (67%) and processed (60%) sweet cheese whey, using it in whey dairy beverages (60%), Ricotta (20%), whey concentrate (15%), and milk blends (5%), which were resold for supermarkets (53%) or industries (20%). However, 27% of the industries discard whey in the effluent treatment system or use as animal feed, suggesting a market for using this by-product. |

Les crevettes, particulièrement Penaeus kerathurus, sont considérées parmi les espèces de crustacés les plus exploitées au niveau des côtes tunisiennes, essentiellement dans le golfe de Gabès. Depuis l’année 1993, une nouvelle espèce de crevette d’origine lesseptienne est apparue dans le golfe et s’est bien adaptée avec ses conditions climatiques et environnementales : c’est la crevette blanche Metapenaeus monoceros. L’objectif principal de cette étude consiste à suivre l’exploitation de cette espèce dans la région du golfe de Gabès, à étudier sa croissance relative et à déterminer la composition des captures selon le sexe. D’après les résultats obtenus nous avons pu constater que, durant la dernière décennie, la production de cette espèce dans le golfe de... |

L’exploitation de la biodiversité marine, notamment via les biotechnologies, offre un réel potentiel de valorisation comme le démontre l'accélération des dépôts de brevets utilisant des substances actives marines. Ce point est renforcé par les particularités uniques de la biodiversité marine. Le défi à l’heure actuelle est de définir les conditions d’exploitation durable dans un contexte de connaissances limitées des écosystèmes concernés. Si les activités actuelles tendent à privilégier la préservation de l’environnement marin, le développement de connaissances et la levée de verrous technologiques permettront probablement à l’avenir d’identifier les ressources d’intérêt puis de les exploiter par des approches industrielles innovantes (e.g.,... |

During the last SCRS plenary meeting, the sub-committee on environment suggested to present a document on the ‘Ecosystem Approach to Fisheries’ (EAF). This document firstly recalls the general scientific and institutional background of EAF, then we propose a synoptic view of EAF, including four main domains: governance, exploitation, resources and impacts on ecosystems. The way that EAF is tackled within the various tuna commissions is then summarised. Finally, we rapidly examine the way the SCRS could cope with EAF issues and we suggest to merge the sub-committee on environment with this on by-catch into a single subcommittee on ecosystem. |

2 ponds (or lagoon) were studied in order to establish the economic possibilities of their exploitation for oysters. Bathymetric and sediment maps were produced using methods described. They indicate a morphological similarity between the ponds, with a superficial broken bed and a regular, flat or gently sloping bed beyond 7 m, the general form reflecting the aerial relief of the adjacent `coast'. The deeper regions had mud or clay sediment, while the edges of the ponds were covered with sand. In more detailed studies it was evident that the banks of Diane were more regular and steep than those of Urbino, and that only in the latter was there a good relationship between the depth of water and the carbon/nitrogen ratio. Differences are thought to relate to... |

The cassava leaf, waste generated in the harvest of the roots, is characterized by high content of protein, vitamins and minerals; however, its use is limited due to the high fiber content and antinutritional substances, which can be removed by obtaining protein concentrates. In this context, the objective of this study was to evaluate protein extraction processes, aiming the use of cassava leaves (Manihot esculenta Crantz) as an alternative protein. Four methods were tested: 1) Coagulation of Proteins by Lowering the Temperature, 2) Extraction by Isoelectric Precipitation, 3) Solubilization of Proteins and 4) Fermentation of Filter Leaf Juice. To obtain the concentrates, the use of fresh or dried leaves and extraction in one or two steps were also... |
