Trenkel, Verena; Berthele, Olivier; Lorance, Pascal; Bertrand, Jacques; Brind'Amour, Anik; Cochard, Marie-laure; Coppin, Franck; Leaute, Jean-pierre; Mahe, Jean-claude; Morin, Jocelyne; Rochet, Marie-joelle; Salaun, Michele; Souplet, Arnauld; Verin, Yves.
Depuis une vingtaine d'années, l'Ifremer organise des campagnes de pêche scientifique en mer du Nord, Manche, Atlantique et Méditerranée concernant les ressources pélagiques, démersales et benthiques. L'objectif prioritaire est de produire des indices d'abondance des principales espèces commerciales. Elles recueillent également des données sur les espèces capturées non commerciales. Les campagnes sont réalisées selon des plans d'échantillonnage standardisés. L'engin de pêche et son gréement, la position des stations, le tri des captures, les prélèvements biologiques suivent des protocoles fixés. Chaque zone étudiée est découpée en fonction de la profondeur, de la latitude ou d'autres critères. L'échantillonnage prévoit un nombre de traits de chalut...

Typologies et composantes des flottilles du sud du Golfe de Gascogne en 1986 - de Noirmoutier à Bayonne ArchiMer
Decamps, Philippe; Leaute, Jean-pierre.
This document presents an analysis of the fishing fleet operating in the Southern Bay of Biscay, based on vessel characteristics and records of fishing activities during 1986, using multivariate ordination techniques. It reveals groups of vessels having similar fishing patterns with regard to utilization of various gears, areas fished and species caught. The results have potential interest for fisheries biologists, and also for economists and regional or national managers.

Leaute, Jean-pierre.
To estimate the size and abundance distribution of juvenile sole (Solea solea) of nurseries in the Pertuis charentais (France) in 2005, a small beam trawl of 2 m wide and 8 mm stretched mesh was used over a hundred sampling points. The other fish catches have also been recorded.

ROMELIGO : Improvement of the fishery knowledge of striped red mullet, whiting and pollack of the Bay of Biscay. The whiting part. ArchiMer
Leaute, Jean-pierre; Caill-milly, Nathalie; Lissardy, Muriel.
This document present the whiting part of the study Striped red mullet (Mullus surmuletus), whiting (Merlangius merlangus) and pollack (Pollachius pollachius) are three species for which individualization of stocks is advanced by ICES in western Europe for areas including the Bay of Biscay and the areas bordering the Iberian peninsula. Since 2012, ICES has provided recommendations with regards to these stocks. These recommendations are given for two‐year periods and are based on an approach adopted by ICES in 2012 in the case of insufficient data for an analytical evaluation (Data Limited Stocks, DLS). For 2013 and 2014, ICES recommended reducing catches by 20% as a precautionary measure compared to 2009‐2011 for the three stocks. Considering that TACs are...

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

Surveying the stock of variegated scallop (Chlamys varia) in Pertuis Charentais straits ArchiMer
Leaute, Jean-pierre; Biais, Gerard; Souchet, Hugo.
The Pertuis Charentais are located in the Bay of Biscay in the middle of the French Atlantic coast. They have an area of 1000 square kilometers and consist of two subsets, the Pertuis Breton and the Pertuis d’Antioche. Variegated Scallop represents a major resource for winter fishing fleet that operates in this space. The variegated scallop (Chlamys varia) is a hermaphroditic bivalve mollusc. It lives on sandy bottoms or on muddy bottom with scattered stones or shells on which it is fixed, in waters where the salinity varies from 30 to 40 ‰ and temperature between 8 and 19 ° C. Approximately 150 boats exploit it normally in the area, mainly in the pertuis Breton, in the bank of La Flotte en Ré, where fishing covers generally more than 80% of the country...

The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing. [...] After a series of "Understanding keys" aimed at helping the reader understand the methodology and...

Les flottilles de pêche des pertuis charentais vues du ciel – Synthèse des campagnes 2004-2005-2006 ArchiMer
Leaute, Jean-pierre.
To identify and estimate the evolution of use of fishing areas operated by professionals fishing vessels in Pertuis charentais, from 2004 to 2006, 3 surveys (40 aerial census) were carried out between May and October. The connection with the species landed by these vessels, and the link with bottom of the sea operated by them was studied. Landings of sole (Solea solea) and cuttlefish (Sepia officinalis) were specifically studied.

Caractéristiques des petites pêches côtières et estuariennes de la côte atlantique du sud de l'Europe - Rapport final - Synthèse. (24 mars 2000 - 23 avril 2002) ArchiMer
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...

Fonctionnement de la nourricerie à sole des pertuis Charentais - Rapport final - Décembre 2010 ArchiMer
Biais, Gerard; Leaute, Jean-pierre; Sauriau, Pierre-guy; Loizeau, Veronique; Robert, Serge; Lavesque, Nicolas; Lepareur, Fanny; Aubert, Fabien; Joassard, Lucette; Paticat, François; Roupsard, François.
La sole est la ressource halieutique qui contribue le plus aux débarquements en valeur des pêches réalisées dans le golfe de Gascogne (52 M € en 2007-09). Elle arrive aussi en première place dans les débarquements de la pêche charentaise (8 M € en 2007-09). Une flottille de grands fileyeurs spécialisés dans sa pêche s'est développée dans le golfe de Gascogne, dont certaines des unités les plus performantes sont basées à Royan. Le port de La Cotinière est l'un des premiers pour les débarquements de sole des chalutiers opérant dans le golfe de Gascogne. Cette espèce contribue aussi à l'équilibre financier annuel de nombreux petits bateaux côtiers.

Variations spatio-temporelles des rendements mensuels des chalutiers dans le golfe de Gascogne, entre 1990 et 1998 ArchiMer
Leaute, Jean-pierre; Poulard, Jean-charles; Forest, Andre.
Les populations marines sont distribuées de manière hétérogène dans l'espace et dans le temps en raison de la diversité des habitats et des exigences des cycles vitaux des espèces. L'intensité de l'exploitation varie également en fonction des métiers, de l'espace et du temps qui structurent les stratégies de pêche. L'objectif de l’étude est de caractériser et décrire les relations qui existent entre les modalités d'exploitation des ressources et leur organisation spatiale à différentes échelles de temps. Dans ce but, l’activité de 164 chalutiers de Lorient, de Saint-Nazaire, des Sables d’Olonne et de La Rochelle opérant dans le golfe de Gascogne est suivie sur la période 1990-1998. Cette approche qui vise à développer les connaissances nécessaires à une...
