A fleet-metier based approach of the small scale fishing activity in the French West Indies 5
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...

Delpech, Jean-paul; Mehault, Sonia; Rostiaux, Emilie; Leaute, Jean-pierre; Leblond, Emilie; Demaneche, Sebastien; Coppin, Franck; Mahe, Kelig; Vaz, Sandrine.
This report is a result of a contract between Ifremer and the French Ministry of Industry. The aim was to provide map the fisheries activity and landings for french fishing vessels, located in the Eastern Channel and the Bay of Biscay during the year 2005. Two areas have been selected: - the "Eastern Channel" area, including 7 administrative departments : Nord, Pas-de-Calais, Somme, Seine-Maritime, Eure, Calvados and Manche. - the "Loire-Gironde" area, including 4 administrative departments : Loire-Atlantique, Vendée, Charente-Maritime and Gironde.

Amélioration de la connaissance de l’activité des fileyeurs dans le golfe de Gascogne 5
Demaneche, Sebastien; Berthou, Patrick; Le Blond, Samuel; Begot, Eric; Weiss, Jerome.
L’analyse des activités de fileyage (nombre de navires, répartition géographique, métiers pratiqués) dans le golfe de Gascogne entre 2013 et 2019 montre une grande stabilité de ces activités dans leur diversité. Les informations sur les caractéristiques des engins de pêche et leur évolution sont encore trop parcellaires pour qu’une conclusion puisse être tirée. L’analyse devrait également être approfondie pour d’autres engins, et notamment ceux mis en oeuvre par les navires étrangers.

Analyse des captures accidentelles de mammifères marins dans les pêcheries françaises aux filets fixes 5
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...

Analyse des captures des flottilles opérant dans l’Ouest de l’Ecosse 5
Dube, Benoit; Demaneche, Sebastien; Biseau, Alain.
L’étude présentée est une analyse des informations recueillies dans le cadre du programme Obsmer en zone Ouest-Ecosse (Division CIEM Via et partie communautaire de la division Vb) au cours de l’année 2011. Quatre métiers pratiqués dans cette zone ont été analysés : 1. Chalutage à espèces profondes en Ouest Ecosse 2. Chalutage à espèces démersales (non profondes) en Ouest Ecosse 3. Fileyage à espèces démersales en Ouest Ecosse 4. Palangres à espèces démersales en Ouest Ecosse Un focus est réalisé sur le cabillaud (proportion dans la capture totale, taux de rejet…) avec une analyse, lorsque cela est possible, des causes ayant amené les rejets (taille légale, quotas…)

Contribution et Dépendance des flottilles de pêche aux espèces commerciales majeures du Golfe de Gascogne 5
Daures, Fabienne; Planchot, Marie; Demaneche, Sebastien; Van Isenghem, Sylvie; Berthou, Patrick; Leblond, Emilie; Jezequel, Michele.
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...

Données statistiques de la pêche du marlin bleu aux Antilles Françaises (Guadeloupe et Martinique) : Proposition de reconstitution d’une série historique 5
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 5
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 5
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...
