| The Fisheries Information System of Ifremer aims to build an operational and multidisciplinary monitoring network for scientific purposes, allowing a comprehensive view of fishery systems including their biological, technical, environmental and economical components. One of its objectives consists in elaborating and providing data and indicators for a widespread public (researchers, fishermen, administration, general public…), including bio-economic diagnostics and assessment of the short and long-term impacts of fisheries management scenario and measures. To further an integrated analysis of the fishery systems, the wide range kinds of data (landings, efforts, biological or environmental observations, economic data…) are managed in a single data... |

| Une réunion technique a été organisée le 21 mai 2013 par la Commission européenne afin de faire le point sur l’état du stock de bar commun (Dicentrarchus labrax) dans les eaux européennes de l’Atlantique du Nord Est. Cette réunion a conclu que le stock de bar peut être considéré comme dans un état « alarmant », et la Commission a demandé aux Etats membres d’identifier les mesures de gestion qu’ils seraient à même de mettre en place dans les meilleurs délais pour obtenir une diminution des captures de 20%. C’est dans ce contexte que la DPMA a adressé à l’Ifremer la présente saisine, en attendant plus particulièrement de l’Institut : - de lister les mesures concrètes applicables aux pêcheries françaises et permettant de réduire les captures et donc la... |

| Introduction: Setting up a policy of coastal fisheries management goes through a preliminary stage of understanding the dynamics of the fishing fleets as much as their tactics. Small fleets, such as those of the Côtes d'Armor, are characterised by: - the boats' home ports are scattered widely, - the heterogeneousness of the types of vessels and fishing gear used, - the versatility of the fishing units, - the plurispecificity of the exploited resource, - the flexibility of operating strategies, that is, the fishing owners' ability to change occupation. However, this flexibility is limited by the availability of the resource, by the market, by the investments granted (boats, fishing materiel), as well as by "cultural" context and know-how. This... |

| Basically, a dredge is a bottom-towed gear and consists of a metal frame with a blade or teeth, to dig into the sediment and extract the shelled molluscs, and a mesh bag to collect the catch. Whereas hand dredging is observed on some intertidal beds (Donax trunculus in France), the use of dredge generally needs a fishing boat. There is a great diversity of dredge types, with specific designs used to target different species in particular beds: Manual dredges for Donax (Donax trunculus), Warty venus (Venus verrucosa) and clams (Venerupis pulastra, Ruditapes sp) Dredges for King scallops (Pecten maximus) Dredges for Warty venus (Venus verrucosa) Dredge for Queen scallops (black and white, Chlamys varia and Chlamys opercularia) Dredges for small... |

| This work is the result of collaboration between the English, French, Channel Isles and Belgian laboratories which are involved in a study of the English Channel. Its subject is the activities of fleets and their interactions, and it complements other work on the biogeographical identification of Channel fish and shellfish stocks (published), and on modelling the fleets' interactions as they exploit theresources (in preparation). The concept of a metier is defined as being the use of one fishing gear to catch one or several species targeted during a particular season in a given area. On this basis, 74 metiers were identified during 1989-90. For each metier we give a brief description of the catching gear, the target species and most usual by-catch, the... |

| In order to provide economic indicators for fisheries, analysis of contribution and economic dependencies of the Bay of Biscay fishing fleets to major commercial species catching in the ICES VIII area is conducted. 9 species are considered (regarding the importance of their landings in this area): Sole, Norway Lobster, Sea bass, Hake, Anglerfish, Anchovy, Sardine, Cuttlefish and Monkfish. The landings data are provided by the Harmonie database of the Fisheries Information System of Ifremer and the analysis per specie is done for the 2005 year on one side and over the period 2000-2005 on the other side. A stock slip is built for each species and presents : - Key figures on landings in the Bay of Biscay (total landings, average price, number of vessels... |

| Juvenile lobsters were reared for 8 months individually in separate tanks in order to obtain separate estimates of growth. Five batches were studied separately according to the type of diet : deep-frozen krill, paste, ¿try pellets and moist pellets. Growth data were collected over 15 first molt stages for each type of prepared diet. Observations deal with size and weight increments at moult and with weight/length relationships. Regression of total lengths over carapace lengths were fitted in each case. |

| The French decommissioning aims at permanently removing vessels from the fishing fleet according to European Union rules laid down within the Common Fisheries Policy. A system of premiums established by the French government is supposed to give the vessel-owners, the incentives to get rid of their fishing unit. This paper details the rules for the applicants and their evolution and it provides a preliminary analysis of the impact of these schemes over the 1991-2001 period. Special attention is paid to the characteristics of decommissioned vessels and of their owners. The problem of windfall gains of these policies is approached, and a first assessment is given. The consequences in terms of capacity adjustment are discussed according to the Multi Annual... |

| Les résultats de ce travail concernent la France métropolitaine (façades Manche / Mer du Nord / Atlantique.) Ils sont établis à partir de l’activité de l’ensemble des navires de pêche professionnels inscrits au fichier Flotte de Pêche Communautaire (FPC) entre 2000 et 2011. Ce rapport donne une description des flottilles et des zones de pêche qui repose sur les résultats de deux analyses : l'une porte sur les données issues de la base SACROIS (présence d'au moins 1 kg de l'espèce considérée dans les captures annuelles de chacun des navires), l'autre fait intervenir la notion de ciblage de l’espèce (que l’on retrouve via les métiers pratiqués dans la base des calendriers d’activité du SIH). Enfin, dans le cadre de la proposition de la Commission d’une mise... |

| In the Caribbean, snappers (Lutjanidae) and groupers (Serranidae) are often heavily exploited by artisanal or industrial fisheries. This paper analyzes the catches of an artisanal fishery selectively targeting these species with a moderate fishing pressure in the Bay Islands (Honduras), and discusses the implications on the understanding of the early stages of development of reef fisheries. Although snappers and groupers are targeted with handlines and spearguns in the whole archipelago, the differences in species diversity and size structure of the catch reveals various exploitation patterns. In most areas, a depletion is observed for the most vulnerable snapper and grouper species, and most other species are mainly exploited in their juvenile phase;... |
