| The scope of this paper is to describe, evaluate, and forecast fishing trip choices of the Bay of Biscay pelagic fleet using random utility modeling (RUM). First, alternative fishing trip choices of this fleet were identified using multivariate statistical methods based on species landings weighted by value and defined as distinct fishing activity or fisheries (termed metiers). A RUM was specified, which included trip components as attributes during the period 20012004 ( a lagged percentage of the value per unit of effort of the main species caught, total value per unit of effort, and inertia in terms of changes from one metier to another). For the main metiers, the proportion of correct effort allocation is 90% during the calibration period of 2001-2004.... |

| From 1986 to 1991, observers on board tuna purse-seiners based in Seychelles allow analysis of data such as oceanographic parameters, aspects of tuna schools and their associated sightings, as well as fishing characteristics (success rate, catches, cpue, species composition, duration of fishing sets). Performances of the four concerned countries (France, Spain, Japan, USSR) are compared. |

| Between the 1st of February and the March 31, 2017, 793 stranded cetaceans were found along the French Atlantic coasts. Common dolphins made up 84% of these strandings, and most of these presented evidence of death in fishing gear. The aim of this work is to test an approach that could help identify the fisheries potentially involved in a given stranding event. To do this we examined how the distributions of likely areas of mortality of bycaught dolphins, inferred from carcass drift modelling, coincide with fishing effort statistics of various fleets, generated from the Vessel Monitoring System, in the area over the same dates. Using reverse drift modelling, two main mortality areas were identified. A total of 3690 common dolphins (IC95% [2230; 6900]) were... |

| 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 fleet 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 the resources (in preparation). The concept of a métier 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 métiers were identified during 1989-90. For each métier we give a brief description of the catching gear, the target species and most usual by-catch, the... |

| Résumé : Le présent article donne une description de l’évolution des paramètres descripteurs de la pêcherie de céphalopodes. Il utilise les statistiques de pêche du CNROP. Les paramètres décrits sont l’effort (nombre de licences, caractéristiques physiques des bateaux, jours de pêche), les captures et les prises par unité d’effort. Les débarquements totaux ont enregistré une hausse atteignant 42000 tonnes en 1992. Cette hausse est due à celle des rendements importants observés pour le poulpe ; ceux des poissons ont diminué continuellement depuis 1990, notamment chez les glaciers. L’effort, en jour de pêche, a enregistré une baisse progressive pour les congélateurs. Par contre, il a presque doublé de 1990 à 1991 chez les glaciers. Les deux modes de... |

| En 1987, 59 chalutiers pélagiques (62-102 m, 2000 – 3880 cv) ont opéré dans la ZEE mauritanienne. Trois pays sont représentés : l’URSS, la Roumanie et l’Allemagne de l’Est. Les captures totales atteignent 441473 tonnes dont 66,5% est pêchée par les soviétiques, 26,3% par les roumains et 7,2% par les allemands de l’Est. Les chinchards (<Trachirus sp et Decapterus rhonchus>) prédominent dans les captures avec 50,8%, les sardinelles en représentent 14,9% et la sardine 7,7%. L’activité des flottilles est apparue, comme en 1986, très marquée par les saisons hydrologiques. |

| Les seiches, poulpes, calmars et nautiles forment la Classe des Céphalopodes de l’Embranchement des Mollusques de grande taille, exclusivement marins. Leur croissance est rapide, leur arrivée à la maturité sexuelle précoce et leur durée de vie courte. Le poulpe a une très large aire de distribution incluant les eaux maritimes tropicales. Elle abonde surtout en Méditerranée, dans les eaux japonaises (Océan Pacifique) et dans l’Atlantique Centre-Est qui s’étend du Maroc à l’Angola. La pêche du poulpe s’est développée au large du Sahara dans les années 1960. Son importance dans la zone du COPACE notamment, au Maroc, en Mauritanie et au Sénégal, s’expliquerait par la raréfaction de ses prédateurs potentiels (Serranidés, Sparidés). Au Sénégal, elle est... |

| Se representa la distribución del esfuerzo y rendimiento pesquero en la pesca de camarón durante el periodo de 2003 – 2005 para el Golfo de Ana María aplicando Sistema de Información Geográfica. Las salidas espaciales en los mapas obtenidos permitieron mostrar que la región de mayor esfuerzo pesquero fue la zona de Manuel Gómez, de empresas de Cienfuegos (EPICIEN), y las cuadrículas pertenecientes a la empresa de Santa Cruz del Sur (EPISUR). Los máximos de rendimiento pesquero reflejados espacialmente, pertenecen a la sub-zona Este de Manatí, al noreste de las cuadrículas de EPISUR y las sub-zonas de Manuel Gómez y Palomo. La representación gráfica de los resultados muestra que no existe una correspondencia entre el esfuerzo y la captura por unidad de... |

| In the Northeast Atlantic fishery for roundnose grenadier Coryphaenoides rupestris, discards account for about 30% of the catch in weight. Data on discards are scarce; however, length distributions and discard rates appear to be relatively stable from year to year. In contrast, landings data available since 1990 show that the average pre-anal fin length has decreased from 20.7 cm in 1990 to 15.2 cm in 2008, resulting in a 58% reduction of the mean individual weight (850 g in 2008) and an increasing occurrence of overlapping class sizes between landings and discards in recent years. For stock assessment, the method of separable virtual population analysis (SVPA) was used. However, because of the lack of discard data for many of the years covered by the... |
