A fleet-metier based approach of the small scale fishing activity in the French West Indies ArchiMer
Guyader, Olivier; Reynal, Lionel; Demaneche, Sebastien; Berthou, Patrick; Daures, Fabienne.
The development of the ecosystemic approach for fisheries supposes to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation. A prerequisite for integrated analysis is the improvement in the knowledge of fleets structure, fleet evolution and allocation of fishing effort in the different fisheries. However, small scale fisheries are often characterized by a lack of knowledge on the vessel fishing activity. This paper first presents a data collection methodology recently applied in the French West (Guadeloupe and Martinique) for the follow up of the whole vessel population. Based on a statistical analysis of these data sets, the paper develops a fleet-metier matrix giving the...

Analyse des captures accidentelles de mammifères marins dans les pêcheries françaises aux filets fixes ArchiMer
Morizur, Yvon; Gaudou, Olivier; Demaneche, Sebastien.
During the years 2008 to 2013 several observations of catches were planned on board of set netters fishing in the bay of Biscay, in the English Channel, in the North sea and in the Mediterranean area (around Corsica). All the observations were done on nets without pingers and they were pooled to provide an average bycatch rate of marine mammals by fleet. Estimates of annual bycatch by using the fishing efforts of the year 2012 were provided by fleet. Harbour porpoise Phocoena phocoena was the most common bycatch in set nets. An average annual estimate of 600 harbour porpoises was obtained for the French fleet; other species recorded in set nets were mainly common dolphin Delphinus delphis, striped dolphin Stenella coeruleoalba and the two species of seals...

Données statistiques de la pêche du marlin bleu aux Antilles Françaises (Guadeloupe et Martinique) : Proposition de reconstitution d’une série historique ArchiMer
Reynal, Lionel; Guyader, Olivier; Demaneche, Sebastien; Le Meur, Chloe; Lespagnol, Patrick.
Blue marlin is fished in the French Antilles around Fish Aggregating Devices (FADs). This fishery commenced in late 1985 and the fishing fleet reached its full potential in the second half of the 2000s. A fisheries information system (SIH), implemented from 2008, enables good estimation of catches and effort around FADs. The data on catch estimates of blue marlin and associated fishing effort are presented herein, as well as the methods used to assess them. From these and a survey of fishing masters, it is possible to reconstitute, year by year, the fishing fleet working around FADs in the French Antilles and to reconstitute a historical series of blue marlin landing.

Fishing strategies, economic performance and management of moored fishing aggregating devices in Guadeloupe ArchiMer
Guyader, Olivier; Bellanger, Manuel; Reynal, Lionel; Demaneche, Sebastien; Berthou, Patrick.
Moored FADs (MFADs) have been a key area for development in Guadeloupe (Lesser Antilles) since the late 1980's. The main objectives underpinning the development of MFADs were to (i) reduce fishing pressure on coastal fishing resources; (ii) boost fishermen's incomes; and (iii) increase local consumption of locally generated fishery products as a proportion of overall consumption. This paper gives an overview of the current structure of Guadeloupe's fishing fleet and fisheries, with a specific focus on MFAD fleets in a relatively unstructured environment with regard to regulation, and so how these fleets operate in a context of unrestricted development of private MFADs. In addressing the following key issues, this paper aims to: assess the economic...

From fleet census to sampling schemes: an original collection of data on fishing activity for the assessment of the French fisheries ArchiMer
Berthou, Patrick; Guyader, Olivier; Leblond, Emilie; Demaneche, Sebastien; Daures, Fabienne; Merrien, Claude; Lespagnol, Patrick.
The development on the ecosystem-based approach to fisheries implies to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation and thus, an improvement in the knowledge of fleets structure, evolution and activity. Since 2000, Ifremer has been implemented a Fisheries Information System (FIS), a multidisciplinary monitoring network allowing an integrated and comprehensive view of fishery systems including biological, technical, environmental and economical components. The FIS covers all the French fisheries, including the so-often neglected small-scale fisheries. One of the originalities of the FIS lies in the fleet monitoring procedure: a comprehensive collection of annual...

Les captures accidentelles de cétacés dans les pêches professionnelles françaises en 2011 : rapport national sur la mise en oeuvre du règlement européen (CE) No 812/2004 – (année 2011) ArchiMer
Morizur, Yvon; Demaneche, Sebastien; Dube, Benoit; Gaudou, Olivier; Dimeet, Joel.
The European Regulation 812/2004 aims to assess the incidental catches of cetaceans in fisheries and to limit as much as possible the bycatch. The program Obsmer manages for France all the observations at sea required by various fishery regulations. This program is implemented by the ministry of agriculture and fisheries (Direction des Pêches Maritimes et de l’Aquaculture) and IFREMER. For the European Regulation 812/2004, the effort dedicated to observation on board of vessels during the year 2011 represents 287 days of sea area for static gears in ICES area VIII, and also 299 days at sea for towed gears in ICES areas VII & VIII and also in the Mediterranean area. In addition some 308 days at sea were dedicated to set nets in areas concerned with...

Modelling seasonal and annual variation in size at functional maturity in the European lobster (Homarus gammarus) from self-sampling data ArchiMer
Laurans, Martial; Fifas, Spyros; Demaneche, Sebastien; Brerette, Stéphane; Debec, Olivier.
Fishers from Le Croisic (France) measure all the lobsters (Homarus gammarus) they capture, indicating their sex and whether the females are ovigerous or non-ovigerous. Between 2003 and 2006 and mainly between April and September, 16 884 lobsters were measured in this manner. These self-sampled data were used to study catchability and functional maturity of lobsters. The sex ratio was 50%, and catchability did not change if a female was ovigerous or non-ovigerous. With the help of a logistic function, a relationship was established between body size and the proportion of ovigerous females. For the study area, 100% of the females were mature upon reaching a carapace length (CL) of 115 mm, and the proportion of ovigerous females reached 70% each year. The L50...

Drogou, Mickael; Laurec, Alain; Bissery, Claire; Mahevas, Stephanie; Demaneche, Sebastien; Begot, Eric; Weiss, Jerome; De Pontual, Helene; Le Goff, Ronan.
La décroissance des rendements de capture professionnelle de bar européen Dicentrarchus labrax à partir des années 2010-2011 a amené la DPMA à demander à l’Ifremer de proposer un programme de recherche visant à mieux connaitre la biologie de l’espèce et à acquérir des données et connaissances permettant d’envisager sa gestion. Parmi les actions de recherche identifiées comme prioritaires, l’action « Données professionnelles » a compris deux grands volets : - utilisation des données de captures professionnelles françaises afin de produire des indices annuels d’abondance en bars adultes, - acquisition de données biologiques (maturité sexuelle principalement et courbe de croissance) sur le bar dans le golfe de Gascogne

Le statut de département français fait de l’île de la Martinique une des régions ultra périphériques (RUP) de l’Union européenne. L’activité des navires de pêche qui exploitent sa ZEE s’inscrit dans le cadre de la politique commune des pêches de l’Union européenne, et la gestion des ressources partagées avec d’autres pays s’exerce dans le cadre des organisations internationales de pêche afférentes. Avec 1098 navires de pêche dont 1074 de moins de 10 mètres, la flotte de la Martinique représentait en 2009 16% de la flotte française. L’absence de données halieutiques depuis les évaluations de Gobert en 1989 a été identifiée à de nombreuses reprises comme un élément critique pour le suivi de l’évolution des activités de pêche et des ressources exploitées,...
