Analyse des campagnes SOLPER - 2005 à 2012 ArchiMer
Leaute, Jean-pierre; Aubert, Fabien; Lepareur, Fanny; Coupeau, Yann; Boiron-leroy, Anne.
A large number of studies on common sole have already been done for years by many research laboratories. This study sought to make a focus on a major nursery on the Atlantic coast, the Pertuis charentais, through the results of eight annual surveys (2005-2012) in late summer (SOLe PERtuis) targeting sole juveniles with a small beam trawl until subtidal zone (<1.50 m). Some of the results obtained in this report confirm previous studies, such as, among others, that more than 80% YOY (G0) occupy muddy or sandy mud bottom at a depth less than 5 m, or that there is a relative correlation between large rainfall in the spring, river flows and abundance of G0 in nursery.   However in the Pertuis Breton this correlation is little expressed by an extension of...

Analyse des flottilles du sud du golfe de Gascogne, de 1986 à 2002 – De Noirmoutier à Bayonne. Description et évolution des composantes de pêche ArchiMer
Leaute, Jean-pierre.
This document presents a comparative assessment of six triennal analysis carried out between 1986 and 2002, on 1300 boats, on average, from the 35 ports of Southern Bay of Biscay fishing fleets (from Loire river to Spanish border). Fisheries statistics allow the identification of different fishing practices and fishing boats associated with them within the fleets. In order to allow comparison and analysis of the evolution that has taken place during the study period, the same variables (gears used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels. Over the period, 11 components, on average, have been identified, grouped in two entities, mobile and fixed gears. If the discriminative characteristics...

Approche du regime alimentaire des juveniles de bars et de limandes en baie de Somme. ArchiMer
Leaute, Jean-pierre.
Stomach contents of juveniles of sea bass (Dicentrarchus labrax ) and common dab (Limanda limanda ) collected during September 1982 from Bay of Somme and the neighbor coast to Penly, were examined. The most part of the diet of young sea bass are the crustaceans, Sedentary polychaetes appear to be the major food item for common dab. For these two young predator species, food preferences tend to change early: cumaceans, then common edible shrimp, for sea bass, Tube worm tentacles, then part of whole individuals are preferred by common dab.

Caractéristiques des petites pêches côtières et estuariennes de la côte atlantique du sud de l'Europe. ArchiMer
Leaute, Jean-pierre; Caill-milly, Nathalie.
The European contract PECOSUDE (Small inshore fisheries of the south of Europe) accepted in 2000 for 2 years concerns French partners (IFREMER, GEOLITTOMER and CEMAGREF), Spanish (AZTI, UPV and IEO) and Portuguese (IPIMAR). For the renegotiation of the PCP in 2002, the aim is to assess the inshore and estuarian fisheries from the Loire to the Portugal. Three levels of study are considered : halieutics (data 1999), socio-economy and marketing (in progress). Frequentation of 12 miles area for France and continental shelf for northern Spain and Portugal, as well as the fishing period lower than 96 hours was determined as the definition of this fishery for the study

Leaute, Jean-pierre.
The European contract PECOSUDE (Small inshore fisheries of the south of Europe) accepted in 2000 (n° 99/024) for 2 years involves French partners (IFREMER, GEOLITTOMER and CEMAGREF), Spanish (AZTI, UPV and IEO) and Portuguese (IPIMAR). The aim is to assess the inshore and estuarian fisheries from Loire estuary to Portugal in view of the negotiations of the PCP in 2002. Three main aspects are considered in the study: fisheries monitoring (data 1999), socio-economy and marketing (data 1999 or 2000). Three main criteria have been established to define the limits of the fishing fleet considered in the study : fishing grounds within the 12 miles zone for the French fleet and the continental shelf and slope (down to 1000 m depth) for northern Spanish and...

Caractéristiques des petites pêches côtières et estuariennes françaises du sud du golfe de Gascogne. ArchiMer
Leaute, Jean-pierre; Caill-milly, Nathalie; Leblond, Emilie.
A travers le projet européen PECOSUDE (n° 99/024) signé en 2000 pour 2 ans, les trois pays participants, la France, l’Espagne et le Portugal ont eu pour objectif de décrire les caractéristiques des petites pêches côtières et estuariennes de la côte atlantique du Sud de l’Europe (de la Loire au Portugal). Ce travail s’est basé sur un bilan des flottilles côtières, du point de vue des typologies, de l’aspect économique et social de l’activité et de la commercialisation des produits issus de cette pêche. La compréhension des systèmes d’exploitation impose l’utilisation conjointe des connaissances de l’halieutique (données 1999), de l’environnement, de l’économie et du social (données 2000). La fréquentation de la zone des 12 milles pour la France et du...

Do changes in environmental and fishing pressures impact marine communities? An empirical assessment ArchiMer
Rochet, Marie-joelle; Trenkel, Verena; Carpentier, Andre; Coppin, Franck; Gil De Sola, Luis; Leaute, Jean-pierre; Mahe, Jean-claude; Maiorano, Porzia; Mannini, Alessandro; Murenu, Matteo; Piet, Gerjan; Politou, Chrissi-yianna; Reale, Bruno; Spedicato, Maria-teresa; Tserpes, George; Bertrand, Jacques.
P>1. The development of ecosystem approaches to environmental management implies the need to account for multiple pressures on ecosystems. Trends in multiple metrics that respond differently to changes in major environmental pressures need to be combined to evaluate the impacts of fishing and environmental changes on fish communities. 2. An exploited fish community is viewed as a three-level food chain in which the two upper levels, or functional groups, are targeted by fishing fleets, while the lowest level is subject to environmental variation. Qualitative modelling is used to predict changes at the two upper levels, that is, top-down vs. bottom-up perturbations. Abundance and length metrics are calculated from survey data for 14 Mediterranean and...

Estimation des stocks de palourdes Ruditapes decussatus, Ruditapes philippinarum sur l'estran oléronais du bassin de Marennes-Oléron. Juin 2009 ArchiMer
Bordeyne, François; Robert, Stephane; Le Moine, Olivier; Leaute, Jean-pierre.
On French coast, Manila clam is a bivalve subject of a large activity recreational and professional hand harvest. Two species are represented in France, European Manila clam Ruditapes decussatus (native) and Japanese Manila clam Ruditapes philippinarum (introduced). Predominance of this last species (more than 90 % of number and biomass), earn them the status of invasive species. Contrary to Arcachon bay, Pont l’Abbé River or Morbihan bay, an estimation campaign of Manila clams stock on Marennes-Oléron bay had never been carried out. The objective of this study: estimate, in number and biomass, the Manila clams stock of two areas. The first affect recreational hand harvest, on Saint-Trojan shore (0.8 km²) whereas the second scopes professional hand...

Evolution des débarquements mensuels des chalutiers artisans de La Rochelle, dans le golfe de Gascogne, entre 1979 et 1993 ArchiMer
Poulard, Jean-charles; Leaute, Jean-pierre.
L'évolution de la composition spécifique des débarquements mensuels par unité d'effort des chalutiers artisans rochelais opérant dans le golfe de Gascogne est analysée sur la période 1979 - 1993. La flottille se caractérise par une certaine stabilité dans le temps, en termes de métier pratiqué, de lieux de pêche fréquentés et d'espèces recherchées. Les navires ont des caractéristiques très voisines et utilisent un engin de pêche ayant peu évolué. Dix huit espèces, représentant en moyenne 94% des apports annuels, ont été retenues pour décrire l'activité des navires qui s'exerce pour l'essentiel entre l'île d'Oléron et Arcachon, depuis la côte jusqu'à l'isobathe de 100 m. L'analyse factorielle multiple (AFM) met en évidence une forte organisation saisonnière...
