The French brown shrimp (Crangon crangon) fishery employs on a seasonal basis around 140 ships about 10 metres in length and with engines of about 100 kilowatts of power. It takes place mainly along the coastal bottoms of silted-up sand at a depth of 2 to 10 metres and occupies principally the coasts of the eastern English Channel and those of the Gulf of Gascony. The brown shrimp catch is performed by bottom trawl, with exempted meshing of 20 mm (stretched mesh), which causes numerous rejects of immature fish that live on the same bottoms. The main part of these juveniles is made up of flat fish (sole, in particular) and of gadidae (whiting and pout). To reduce these undesirable catches that are also detrimental to other fisheries, some ingenious...

Starting from the year 2000, the European Union planned to establish the use of a selective trawl in brown shrimp (Crangon crangon) fisheries. In fact, the brown shrimp is caught by a bottom trawl equipped with stretched 20 mm exempted meshing in estuary areas where the nurseries of flat fish and gadidae are located. For Vilaine's estuary, Dupouy et al (1997) estimated at about 1 tonne of flat fish and one tonne of gadidae the loss in equivalent fish of marketable size, per landed tonne of brown shrimp. In this document, the authors introduce improvements resulting from the use of selective trawls developed in France (Asselin and Devismes trawls), and they show by what means the selectivity of these trawls can be improved further.

Approche multi-modèles appliquée à la plie et au merlan de Mer du Nord et à l'anchois du Golfe de Gascogne ArchiMer Loots, Christophe. Spawning is a crucial phase of fish life cycle as it ensures the renewal of individuals in the population. The identification of factors that influence its spatial dynamic is therefore a key feature as it will affect the reproduction success of fish population. A multi-model approach has been developed in order to identify factors that control the spatial distribution of spawning adults of plaice and whiting in the North Sea and of anchovy in the Bay of Biscay. Generalised additive models have been used to relate presenceabsence of adults and their abundances to several hypotheses of control external (geographical position and environment) and internal to the population (spatial dependency, size, age structure and memory). Models were then ranked according...

Ano: 2009 URL: http://archimer.ifremer.fr/doc/2009/these-7400.pdf Estimation de l’âge du merlan (Merlangius merlangus) ? ArchiMer Dufour, Jean-louis; Chantre, Celina; Elleboode, Romain; Mahe, Kelig. Le merlan (merlangius merlangus) est une espèce commerciale importante suivie au niveau européen. La pièce calcifiée utilisée pour l’estimation de l’âge du merlan est l'otolithe. Parmi les 3 paires d'otolithes, ce sont toujours les plus gros, les sagittae qui sont utilisés. Ils conservent la séquence complète des marques de croissance enregistrées (Panfili et al., 2002). Pour observer au mieux ces structures, la technique de coupe transversale a été retenue comme la plus précise (ICES WKARWHG2 REPORT 2016). Les images obtenues sont soumises à l’interprétation par les experts européens. Ce rapport propose de décrire précisément les structures observables sur les images obtenues par la technique de coupe transversale. La variabilité des structures est...

En mer du Nord, il a été montré que la prédation qu'exercent entre elles les espèces exploitées constitue un des facteurs majeurs qu'il faut prendre en compte pour analyser les effets de différents régimes de gestion des ressources halieutiques. Pour cette zone, les biomasses de poissons consommées à l'intérieur du système par les principaux prédateurs sont équivalentes à celles qui y sont pêchées. En particulier le merlan (Merlangius merlangus) y a été reconnu comme un prédateur majeur de juvéniles des autres espèces, au point que pour la modélisation multispécifique des pêcheries les valeurs de mortalité naturelle pour les poissons les plus jeunes sont fonction de la biomasse du stock de merlan. Il existe un stock de merlan dans le Golfe de Gascogne... Tipo: Text Palavras-chave: Merlangius merlangus L.; Dynamique de population; Merlan; Gophe de gascogne. Ano: 1993 URL: https://archimer.ifremer.fr/doc/1993/rapport-6944.pdf Etude d'une gestion optimale des pecheries de langoustines et de poissons demersaux en mer Celtique ArchiMer Laurec, Alain; Charuau, Anatole; Perodou, Jean-bernard; Nedelec, Daniel; Biseau, Alain; Durand, Jean-louis; Rivoalen, Jean-jacques; Dupouy, Herve; Le Louarn, G.; Leroux, L.. The general study, scheduled from 1984 to 1986, aims at providing a judgement about the fisheries in the Celtic Sea. This area has been chosen because it is frequented by EEC vessels with, for the time being, a large majority of French vessels. Activities there are easier to monitor than anywhere else as coastal fisheries are little developed in the area. The final product will consist of a certain number of hypotheses about the planning strategies that could be implemented in the Celtic Sea. The main idea is, firstly, to conduct analytical studies, stock by stock, in order then, to synthesize them into a model integrating the interactions between fleets in relation to their target species. A bio-economical model, deriving from the latter, will enable the...

Ano: 1985 URL: http://archimer.ifremer.fr/doc/1985/rapport-3671.pdf Pêcheries bigoudenes. Bilan des connaissances Activités de pêche, Ressources, Gestion ArchiMer Biseau, Alain; Maguer, Cedric; Sanz Aparicio, Céline. Located at the far south-west of Brittany, the pays bigouden is the first of the French maritime regions in terms of landed value and the second one in weights. The bigouden fishing practices are characterised by a large diversity of target species and métiers. Studying the fishing practises leads to a description of the various métiers and fishing strategies together with their trends over the last ten years. Identification of métiers is based on multifactors analysis. Using a classification method based on thresholds of species landings then allows a more objective analysis and leads to a more quantitative characterisation of the trawl métiers, which represent more than 80% of the total fishing activity of this region. Two métiers are based on Nephrops...

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...

The stocks of whiting (Merlangius merlangus), pollack (Pollachius pollachius) and striped red mullet (Mullus surmuletus), are considered by ICES as Data Limited Stocks (DLS) for the Bay of Biscay areas, those bordering the Iberian Peninsula as well as the Celtic Sea for red mullet. In the case of insufficient data for an analytical assessment, ICES has recommended, for 2013 and 2014, to precautionarily reduce landings by 20 % compared to the period 2009-2011 for these 3 stocks. In order to improve knowledge to fill the gaps in the status of these stocks, and to extract them from the DLS category, the ROMELIGO project has: i) analyzed available data on both catches and professional fishing activity, Captures per Unit of Effort (CPUE) to identify reference...
