Amélioration de la sélectivité des chalutiers Pêcherie multispécifique – Manche - Mer du Nord (selecmer) ArchiMer
Leonardi, Sophie; Rubin, Alex; Meillat, Marc; Coppin, Franck; Delpech, Jean-paul; Morandeau, Fabien; Larnaud, Pascal.
Ce rapport fait la synthèse des travaux réalisés en 2008 et en 2009 au cours du programme Selecmer. Celui-ci, réalisé à l'initiative des professionnels de la pêche en partenariat avec l'Ifremer, avait pour objectif de travailler à améliorer la sélectivité du chalut de fond qu'ils utilisent afin de diminuer les rejets des individus hors-tailles1, en particulier pour le merlan, tout en limitant les pertes commerciales immédiates. Une première phase a consisté à tester l'efficacité de fenêtres à mailles carrées. La deuxième phase a eu pour objectif de développer une grille sélective. Des essais en bassin et des campagnes vidéo en mer ont permis d'apporter des ajustements aux dispositifs sélectifs. L'ensemble des essais de sélectivité à bord des navires de...

Compléments à la réponse à la saisine 2008-1014 sur les pressions potentielles des engins de pêche sur les habitats et espèces listés dans les Directives Habitats (92/43/EEC) et Oiseaux (2009/147/CE), pour les sennes danoises et écossaises ainsi qu’envers les récifs côtiers et les récifs circalittoraux.

Projet CELSELEC. Amélioration de la sélectivité des chalutiers hauturiers en mer Celtique ArchiMer
Lamothe, Julien; Larnaud, Pascal; Fiche, Marion; Robert, Marianne; Morandeau, Fabien; Vacherot, Jean-philippe; Scavinner, Marion; Simon, Julien.
In the context of the new European Common Fisheries Policy and in particular the Landing Obligation, this report synthesizes the trials which were carried out between 2014 and 2016 on French bottom trawlers operating in the Celtic Sea and Western Channel, to decrease their discards. All the detail of the experiments and their results are attached in the voluminous appendices. After a state of the art and various workshops organized in partnership between fishermen, equipment manufacturers and scientists, 3 basic devices were selected for the trials, according to the main fisheries: - 100 mm square meshes cylinder - SMC - (in addition to the mandatory 100mm and 120 mm square mesh panels - SMP) with or without scaring floats ; - Extension + codend in...

Essais de dispositifs sélectifs par les flottilles chalutières du golfe de Gascogne. Programme REDRESSE ArchiMer
Mehault, Sonia; Larnaud, Pascal; Rimaud, Thomas; Cuillandre, Jean-pierre; Morandeau, Fabien; Simon, Julien; Vacherot, Jean-philippe.
The landing obligation implemented under the Common Fisheries Policy promoted the development of fishing gear selective devices. The REDRESSE project conducted in the Bay of Biscay was the opportunity for trawl fleets targeting cephalopods, Nephrops and demersal fish to continue to test various selective configurations to reduce their discards levels. The sea trials were carried out onboard of commercial fishing vessels and the experimental tows were sampled by an observer. Most of the selective devices were tested under the twin trawl method, with on one side the gear to be tested and on the other, the standard commercial gear. Other devices were tested with the parallel or alternate haul method. The data obtained were used to describe the catch species...

Rapport d’étude final du projet REJEMCELEC - Réduction des Rejets en Manche et mer Celtique par la Sélectivité des engins de pêche ArchiMer
Lavialle, Gael; Morfin, Marie; Simon, Julien; Morandeau, Fabien; Vimard, Mathieu; Larnaud, Pascal.
In the context of the new European Common Fisheries Policy and in particular the Landing Obligation, the two Producers Organisations, COBRENORD and  OPN launched the REJEMCELEC project in partnership with IFREMER and net suppliers. It was set in a complementary way to the CELSELEC project. The main goal is to reduce whiting, haddock and pelagic discards for single bottom trawlers fleets targeting whiting, squids, cuttlefish and monkfish within the Western Channel. A specific fleet targeting hake and John Dory in Celtic Sea during summer (around Scilly Island) was also studied in order to reduce discards of small haddock, hake and boarfish. After a state of the art, an analysis of quantitative data and various workshops organized in partnership between...

Lorient Flume tank ArchiMer
Vincent, Benoit; Simon, Julien; Vacherot, Jean-philippe; Morandeau, Fabien; Larnaud, Pascal; Kopp, Dorothee; Mehault, Sonia; Morfin, Marie; Savina-rolland, Marie; Marc, Emilie.
The Lorient flume tank is an hydrodynamic facility available for any qualification and observation of submerged objects in still or moving water. It is a closed loop circulating tank filled with fresh water.  The fluid is moved with a 70 kW pump-motor with a velocity between 0 and 1 m/s and homogenized with a series of pressure drop systems. The overall dimensions are 24.50 m long, 7.50m wide and 3.30 m high. The part where experiments can be set up is 12m long, 2.6 m wide and 1.5 m deep.  A mobile bottom belt can be synchronized with the water flow velocity and enables to simulate the seabed velocity relatively to a towed object. The overall process of the facility is controlled by a user friendly interface.
