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...

Biologie et pêche du céteau (Dicologoglossa cuneata Moreau) dans le sud du golfe de Gascogne ArchiMer
Forest, Andre.
Le céteau, Dicologoglossa cuneata (Moreau), est pour les pêches françaises en Atlantique, une espèce d'importance économique très secondaire : il n'apparaît pas dans les statistiques de la Marine Marchande et l'on peut estimer sa production aux environs de 450 ou 500 t par an. Il fait néanmoins l'objet d'une pêche particulière de la part de bon nombre de chalutiers artisans des Sables d'Olonne, de l'Ile d'Yeu, de La Rochelle, de l'Ile d'Oléron et d'Arcachon.

Biologie et pêche traditionnelle des crevettes pénéides dans l'embouchure d'un fleuve en milieur semi-aride (sud-ouest de Madagascar) ArchiMer
Laroche, Jean; Benoely,; Siaviri, A.
Traditional fishing using beach seines was studied over a period of one year at the mouth of the Onilahy river. The catches/efforts were recorded on a daily basis, biological sampling and the measurement of hydrological parameters being carried out twice a month. The moderate variations of salinity and temperature (14 < salinity < 35; 25 degrees C < temperature < 30 degrees C) which were observed in the estuary can be explained by the semiarid climate of the area. Four species of penaeid shrimps are to be found on the Onilahy: Metapenaeus monoceros, Panaeus indicus, Penaeus monodon and Penaeus japonicus, which were mainly caught at the subadult/adult stage with a Carapace length between 10 and 50 mm. The presence of these important sizes at the...

Campagne PROCELT1 : prospection des ressources halieutiques benthiques et démersales aux accores du plateau celtique ArchiMer
Latrouite, Daniel; Dorel, Didier; Dupouy, Herve; Quero, Jean-claude.
The « PROCELT 1 » scientific cruise took place from 5 to 28 June 1984 aboard Ifremer's research vessel «Thalassa». Its main objective was to prospect for benthic and demersal biological resources, whether traditionally fished or potential species, on the Celtic shelf-break between 47°30' N and 52°00' N and to assess them whenever possible. 83 hauls were made in stratified random sampling based on bathymetric criteria (between 200 and 800 metres) using a Lofoten trawl with 31.20 metres of headrope and 17.70 metres of footrope. This document reports on the main results of the survey: biological observations and abundance of main species per layer, observations of invertebrates and collecting of material. 26 spec sheets give the biological observations...

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.

Caractérisation biologique et variation des captures de la grande alose (Alosa alosa) par unité d'effort sur le fleuve Adour (Pyrénées Atlantiques, France) ArchiMer
Prouzet, Patrick; Martinet, Jean-pierre; Badia, Jacques.
The study of logbooks from commercial fishermen on the Adour River and commercial samples allowed characterization of the allis shad population (Alosa alosa L.) caught during the period 1988-91. A better knowledge of the influence of hydroclimatic factors (rate of river flow and intensity of tidal coefficient) on the catchability of the species in that never was also obtained. Allis shad are mainly recruited to this fishery from the beginning of April to the end of May: between 78 and 89 % depending on year. Males in the population were on average younger than females. However, at the same age, males were significantly smaller in size and in weight than females. These results reinforce the knowledge already obtained on French stocks in the Loire and...

Compactation for a better management of marine biomass: applications to fish discards and by-products ArchiMer
Perez-galvez, Raul.
In the framework of the future application of a zero-discard policy in EU fisheries, this thesis aims to develop and implement an efficient and integral waste management both on board the fishing vessels and in land (fish auctions and fish processing industry). To this end, it proposes a compaction operation able to reduce the volume and the water activity of the fish wastes, thus favouring their handling and reducing the economical costs associated to their transport and storage. To asses the viability of a waste compaction operation, the main operation factors governing the process were identified, and their influence upon the performance of the compacting operation was investigated by a statistical approach. Sardine was chosen as fish species since it...

Compte rendu des essais de pêche du Laminaria hyperborea ArchiMer
Arzel, Pierre; Mingant, Christian; Noel, Philippe; Gourronc, Eugene.
Introduction During the month of April 1994, the "Ressources Halieutiques de l'Ifremer" laboratory (Ifremer Halieutic Resources) in Brest tested tools to be used for the harvesting of Laminaria hyperborea as requested by Système Bio-Industries. The first results of this trial campaign are as follows: The tools are effective as far as interspecific as well as intraspecific selectivity. Rightly so, Laminaria hyperborea accounts for nearly 100% of the harvest. We also noticed that only large size plants are harvested, commercial harvest is satisfactory in terms of yield. However insufficiencies still remain. Comb efficiency is low, since the actual harvest only represents 10 to 12% of the stipes collected when the machine goes through. This low efficiency...

Contribution à l'étude de la crevette rose Palaemon serratus (Pennant) : Exploitation, Biologie, Elevage, Epidémiologie ArchiMer
Campillo, Albert.
This these is the result of several years of investigations conducted on the common prawn Palaemon serratus in the Roscoff (northern Brittany) and Yeu (bay of Biscay) sectors of the French Atlantic coast. Following a description of the fishery and fishing strategies, it deals with the species biological aspects, focusing on growth, lifespan, sex-ratio and breeding. Hypotheses on the reasons for apparent variations in interannual abundance are drawn up and compared with field observations. The second part is devoted to production experiments in a controlled environment (hatchery), explaining how larvae are obtained and their development and survival with respect to food, density and physical parameters like salinity and temperature. The link between...

Contribution a l'étude de l'étrille Necora puber dans le Mor-Braz : données halieutiques, biologiques et pathologiques ArchiMer
Wilhelm, Gwenaëlle.
The velvet swimming crab Necora puber, commonly found on the French coast was an important resource for inshore fishermen of the Mor-Braz sea in Southern Brittany before the production collapsed in 1985. Although there are still many uncertainties as to the reasons for this, we note that the collapse took place after a significant ecological imbalance which locally caused massive mortality of many marine organisms in 1982. Without being obviously linked to the former point, mortality due to pathological causes was observed in velvet swimming crabs. Seeing the lack of general knowledge about these crabs, this study was designed to acquire data about its fishery and its biology. The first part focused on fleet, fishing effort and yield trends in the...

Détermination de l'effort optimal de chalutage benthique dans le golfe de Tunis OceanDocs
Zarrad, R.; Gharbi, H.; Missaoui, H..
The production models of Schaefer and Fox are used to determine the optimal effort of benthic trawlers in Tunis Gulf. The necessary data for the application of these models were collected from services of General Direction of Fishing and Aquaculture (DGPA). They are related to the two fisheries which exploit the benthic resources : trawling and coastal fishing and are extended over 12 years (from 1988 to 1999). The unit of effort selected, which gives the best correlation coefficient is the number at days at sea times : The day number at sea time the engine power of the fleet. In the current exploitation state, the optimal effort is estimated at 15 benthic trawlers with an average power of 450 cv.

Champigneulle, A.; Degiorgi, F.; Raymond, J. C.; Cachera, S..
The technique of otoliths fluoromarking has been used to evaluate at a large scale the practices of brown trout (Salmo trutta L.) stocking (540 000 - 570 000/year, most of them as sac fry) for three cohorts 1994-95-96 in a part of the River Doubs having a length of 40 km and fragmented in three zones (upstream, median, downstream) by three hydroelectric dams. For each of the three cohorts, there is a rather high contribution (23 to 60% according to the zone) of the stocked fry to the automnal 0+ standing population. The mass marking of all the stocked fry allowed to show that the dynamics of the contribution of the two components of recruitment (natural or stocked) differed. Indeed, the contribution of stocking decreased with time when measured in the...

As part of a larger project financed by the European Union programme "Community initiative PESCA" on the study of "small scale fisheries" in Aquitaine (France), an estimation of the stock of clams in the Bassin d'Arcachon has been conducted. A two-stage stratified random sampling survey has been designed. Samples have been collected using a Hamon bottom sampler in 237 locations distributed over 24 km2. The clam Tapes philippinarum, which appeared in the basin following a series of aquaculture experiments in the mid eighties, is now the main species accounting for more than 90% of the abundance and the biomass, largely overcoming the European species Tapes decussata. The mean abundance and biomass (26 clams / m2 et l28g / m2) are above those estimated in...

The exploited stocks of wild bivalves (common cockles, dog cockles, clams, and spisules) in the Norman-Breton gulf vary according to the fishing activity and the environmental conditions. Different studies, carried out by the Ifremer in this region (between 1982 and 1998), enabled the evaluation of the stocks available for fishing as well as the collection of data on these species (demographic structure, growth...). For more information on the 1993-1994 studies and a presentation of the site and the fishery please refer to the reports by Berthou, 1987 and Noël et al, 1995. The bivalve expedition conducted in May 2002, enabled us to update the data on the populations of dog cockles and banded carpet shells, then of spisules and clams, using the same...
