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...

Campagne Techorhago ArchiMer
Vacherot, Jean-philippe.
Pour être en phase avec les recommandations de la communauté européenne, les missions ORHAGO doivent utiliser un chalut à perche pour la constitution des indices d'abondance de sole dans le golfe de Gascogne. Un chalut à perche de 4 m (environ 2000 kg) a été construit et acheté aux Pays-Bas dans l'optique des futures campagnes à la mer. La campagne TECHORHAGO visait à essayer et à mettre au point les différentes manoeuvres de mise à l'eau et de virage du chalut en le remorquant sur les deux treuils du Gwen-Drez. L'EROC (Engin Remorqué d'Observation des Chaluts) était embarqué.

Evaluation de la faisabilité et de la pertinence des protocoles « macrodéchets de fond » et « zooplancton gélatineux » testés sur les campagnes halieutiques côtières de l'Ifremer en 2017 ArchiMer
Lehmann, Léa.
The optimization of Ifremer's survey as a support of MSFD monitoring has been available since 2016 on the offshore fisheries surveys. Several protocols have been implemented, such as the “seafloor litter” and “gelatinous zooplankton” protocols. The aim of both protocols is to respectively collect data about the spatio-temporal evolution of waste and determine their origin, and to monitor the biodiversity of gelatinous zooplankton. From September to November 2017, they were tested on coastal surveys: NOURSOM, NOURNEINE, NOURMONT, ORHAGO, and NURSE. These surveys were primarily deployed to estimate the bentho-demersal species stocks as well as their spatio-temporal and trophic dynamics by a standardized sampling. Thus, this paper aims to assess the...

Le chalutage à perche ArchiMer
Jean-pierre, Dugauquier.
This study on pole trawling was done with the goal of giving some clarification about a theoretically prohibited fishing technique that is little used in France. However, fishermen from some countries routinely practice pole trawling authorised at the European level, which poses a few problems from the point of view of French regulations, and it is on an exempt basis that this technique is used by some boats in Brittany and Normandy, but the only large fleet that is practising pole trawling intensively by using boat booms is based in Dunkerque's harbour. It is the reason for which we studied the Dunkerque fleet's activity and operation; the technical aspect of the trawl was described at length. The contentious situation brought on by the practise of this...

Rapport de la campagne SOLPER 1 (26 août – 2 septembre 2005) ArchiMer
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.

Rapport de la campagne SOLPER 2 (28 août – 2 septembre 2006) ArchiMer
Leaute, Jean-pierre.
To estimate the size, age and abundance distribution of juvenile sole (Solea solea) of nurseries in the Pertuis charentais (France) in 2006, 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 and water temperatures measured.
