Variedade de mandioca e um dos principais componentes para o desenvolvimento do sistema produtivo dessa cultura, alem de constituir uma tecnologia que nao implica em custos adicionais para o produtor. Apesar da mandioca apresentar um alto potencial produtivo, estimado por COCK (1974) em 90 t/ha/ano, a produtividade nacional esta em torno de 12 t/ha. Um dos fatores que tem contribuido para a baixa produtividade desse cultivo no Brasil, e o uso de variedades com baixo potencial produtivo. A demanda por novas variedades de mandioca vem crescendo constantemente, a medida que surgem novas alternativas de uso pelo produto, bem como a expansao de novas fronteiras agricolas para o plantio dessa cultura. Para atender essas demandas, e importante definir-se as... |

The principal objective of the work carried out in the deep waters adjoining the island shelf around Martinique between July 1991 and april 1992 was to establish an initial inventory of potentially exploitable deep benthic resources.The cylindrical lobster pot used during fishing experiments allowed the catch of a varied carcinological marine organisms of which six species at least have economic interest : 5 species of shrimp all belonging to the sub-order of Caridea of the Pandalidae family : Plesionika edwardsi, P. (macropoda) polyacanthomerus, P.laevis, Heterocarpus ensifer and H.laevigatus, and one species of prawn of the Nephropidae family : Eunephrops cadenasi. The yields, compared to those of commercial fishermen, were medium or good for Plesionika... |

This paper contains a description of the Lepidoptera, exclusive of the Tortricidae, Tineidae, Orneodidae, and Pterophoridae, of t he Seychelles Archipelago, and of the coral islands of Aldabra, Assumption, Cosmoledo and Astove, though the collections from the three latter islands are too small to be considered representative. The collections from the Seychelles were obtained very largely by Mr Hugh Scott, who spent eight months (July 1905-March 1909) in the group and devoted the whole time to entomological collecting.

This report compiles 17 short and illustrated syntheses concerning the natural strategies of reproduction and the artificial control of the reproductive process for the flat oyster, Ostrea edulis, the japanese oyster, Crassostrea gigas, the mussels, Mytilus edulis and My ti/us galloprovincialis, the scallop, Pecten maximus. An additional syntheses is presented, as a comparison within molluscs, which are the main research topics at IFREMER concerning the artificial control of the reproductive processes in Marine Fish. Three main subjects are documented : 1. the ecophysiology of the natural period of reproduction in the wild, 2. the methods developed in the hatcheries for the artificial control of the reproductive periods, the gametes collection and the... |

Due to the unsuitability of the north brittany coastal fishing grounds for trawling, the fishing activity of the harbours of this coast has been oriented towards the catch of invertebrates and peculiarly the large crustaceans. After, in the beginning of the XIX century, looking for lobster and spiny lobster, fishing has been, since the seventies, centered on the catch of the edible crab (Cancer Pagurus) and of the spider crab (Maia squinado). The first part of this document introduces the context of the exploitation and the concerned fleets. The second part treats of the biological parameters of the edible crab: growth, reproduction, migration and pathologies. The third part, devoted to the exploitation and the monitoring of the edible crab stock, is an... |

Contrary to the situation in Europe, Réunion Island is the only French department whose fishing has increased considerably for five years, as far as artisanal fishing linked to DCPs (Fish Concentration Plans), but also semi-industrial longline fishing and industrial fishing in southern oceans are concerned. Two capital events contribute to the quick development of tuna fishing and provide Reunion Island with access to its pelagic resources. The setting up in 1988 of the first DCPs by the French Research institute for the exploitation of the sea (Ifremer) resulted in a real upheaval of artisanal fishery and relaunched a sector which had been slowing down since 1980. In 1991, witnessing the success of Asian longline boats unloading on Reunion Island, a local... |

Sheltered by the Isle of Oléron, benefiting from the supply of fresh water from two rivers, the Charente and the Seudre, the Marennes-Oléron basin enjoys, in Charente-Maritime, a privileged topographical situation. Oyster farming, one of the first forms of marine aquafarming, represents the central business activity of this shoreline of the Charente, whose originality is to own more than 90% of the oyster pits currently listed in France. This peculiarity has been described by several authors: Moreau (1970), Gras (1976), Grelon (1978) and Marteil (1979). |

Le 3 juin 1905, dans l'après-midi, nous quittions Tromsö à bord de la Belgica, affrétée et équipée par le Duc d'Orléans pour une croisière océanographique dans la Mer du Groenland , et procédions vers le nord. Le lendemain, nous perdons de vue la côte norvégienne. La saison n'étant pas encore propice à la navigation dans la banquise qui encombre la Mer du Groenland, nous nous dirigeons d'abord vers le Spitsbergen que nous prendrons comme point de départ de notre campagne océanographique... Dans les premières semaines, nous sommes particulièrement contrariés par le temps et devons, à diverses reprises, mouiller à l'abri des îles septentrionales du Spitsbergen pour étaler quelques forts coups de vent de la partie ouest. Nous visitons ainsi, tour à tour,... |

L’implantation récente de Rapana venosa, gastéropode prédateur originaire d’Extrême Orient, en plusieurs points du globe (USA, France, Uruguay, Argentine) et son impact sur les populations de bivalves autochtones justifient un certains nombre de recherches engagées par les pays concernés. Le présent rapport compile les dernières informations scientifiques disponibles sur la biologie de R. venosa. Par ailleurs, l’opportunité d’obtenir des pontes en milieu naturel et en captivité en 2001 a permis de faire des observations sur la maturation des larves. Il apparaît que dans les conditions de températures régnant en Baie de Quiberon en été (18 à 22°C), les larves de Rapana venosa sont capables d’éclore. L’impossibilité, dans cette expérimentation, d’amener ces... |
