| The reduction of by-catch mortality is an objective of the ecosystem approach to fisheries and a request made by consumers. Elasmobranchs, an important component of the French tropical tuna purse seine fishery by-catch, are currently thrown back into the sea. Fishers interact with various types of elasmobranchs that range widely in size, weight and shape, and could pose various degrees of danger to the crew. A diversity of discarding practices within the fleet were reported, some practices were considered suitable, others needed to be adapted and improved and others simply had to be banned. The majority of the crews were likely to improve their handling practices if they were presented with practical suggestions that were quick and easy. Combining... |

| The scope of the European Union Plan of Action for Sharks covers directed commercial, by-catch commercial, directed recreational, and by-catch recreational fishing of any chondrichthyans within European Union waters. It also includes any fisheries covered by current and potential agreements and partnerships between the European Union and third countries, as well as fisheries in the high seas and fisheries covered by RFMOs managing or issuing non-binding recommendations outside European Union waters. Scientific advice for the purpose of the management of shark species in the high seas is carried out mainly via the Scientific Committees of the relevant Regional Fisheries Management Organisations (RFMO), as well as through specific projects by national... |

| Recently, declining populations of several pelagic shark species have led to global conservation concerns surrounding this group. As a result, a series of species-specific banning measures have been implemented by Regional Fishery Management Organizations (RFMOs) in charge of tuna fisheries, which include retention bans, finning bans and trading bans. There are both positive and negative aspects to most management measures, but generally, the positive aspects outweigh the negatives, ensuring the measure is beneficial to the resource and its users in the long term. Banning measures are a good first step towards the conservation of pelagic shark species, especially since they improve conservation awareness among fishers, managers and the public. Measures... |

| La loi sur la Protection de la Nature de juillet 1976 prévoit dans son article 2 la réalisation "d'études d'impacts sur l'environnement", Le Centre National pour l'Exploitation des Océans (CNEXO) réalise de telles études depuis plusieurs années en particulier dans le cadre de son service d'études marines appliquées intitulé "Unité Littorale. C'est ainsi que le CNEXO étudie, en liaison avec les universités, le CNRS, l'ISTPM des laboratoires d'analyses, des organismes privés et publics, le Ministère de la Culture et de l'Environnement, divers dossiers d'impacts sur l'environnement marin tels que: - Implantation de centrales nucléaires sur le littoral, - constructions portuaires, - exploitation de sables et graviers en mer, - rejets polluants solides et... |

| AVANT-PROPOS : Dans le cadre du programme d'équipement nucléaire, Electricité de France a confié au Centre National pour l'Exploitation des Océans l'instruction des dossiers écologiques concernant une liste de sites envisagés pour l'implantation de centrales sur le littoral. L'objectif de ces dossiers "d'avant-projet" est de fournir à Electricité de France les contraintes d'ordre écologique intervenant au niveau du choix du site. Le présent rapport a pour intitulé: "Etude écologique d'avant-projet sur le site de Penly : le milieu pélagique". Il vient ainsi compléter l'étude écologique d'avant-projet réalisée par le CNEXO (Unité Littoral) en 1976 et dans laquelle les efforts portaient sur le domaine benthique: peuplements de l'estran et des fonds côtiers... |

| Forty one manned submersible dives were carried out during 2 cruises in the Bay of Biscay covering a range of depth from about 100 to 2100 m. Chondrichthyan species were observed in most of the dives, some of them were easily identified and their behaviour could be studied. Twenty-two chondrichthyan species (9 sharks, 8 rays and 5 chimaeras) were recorded. Shark species were always seen active except Scyliorhinus canicula and Galeus melastomus. Some representatives were found motionless on the bottom, sometimes forming groups for the first species. Chimaeras appeared to strongly react to the presence of the submersible. The density of chondrichtyes and their relative frequency in the total fish assemblage were estimated, the results are globally consistent... |

| The objective of this project was to obtain scientific advice for the purpose of implementing the EUPOA on sharks as regards the facilitation of monitoring fisheries and shark stock assessment on a species-specific level in the high seas. The study was focused on major elasmobranch species caught by both artisanal and industrial large pelagic fisheries on the High Seas of the Atlantic, Indian and Pacific area, which are currently monitored and potentially managed by respective Tuna RFMOs. Estimated “potential” shark species catch in the Indian Ocean is around 160,000 t for 22,000 t. presently declared (7 times higher than declared). Considering all sharks that are not reported at species level, the total amount of shark declared was around 100,000 tons... |

| Tuna fisheries have been identified as one of the major threats to populations of other marine vertebrates, including sea turtles, sharks, seabirds and marine mammals. The development of technical mitigation measures (MM) in fisheries is part of the code of conduct for responsible fisheries. An in-depth analysis of the available literature regarding bycatch mitigation in tuna fisheries with special reference to elasmobranchs was undertaken. Studies highlighting promising MMs were reviewed for four tuna fisheries (longline, purse seine, driftnets and gillnet, and rod and line – including recreational fisheries). The advantages and disadvantages of different MMs are discussed and assessed based on current scientific knowledge. Current management measures for... |

| Le but de cette synthèse documentaire, entreprise à la demande de l'Electricité de France, est de faire le bilan des connaissances actuelles sur l'écologie du littoral compris entre Le Havre et Dunkerque. Il s'agit d'un travail bibliographique, c'est-à-dire que les informations présentées sont extraites de la littérature. Aucune mission sur le terrain n'a été effectuée. Une compilation des documents relatifs à l'écologie de la zone étudiée a été réalisée et une analyse de ces documents a été faite. Le Centre National pour l'Exploitation des Océans - Unité Littoral - s'est chargé de la partie écologique (s.t.) tandis que l'aspect sédimentologique a été traité par le Laboratoire Central d'Hydraulique de France. Les caractéristiques hydrologiques de la... |
