A restricted fishing area as a tool for fisheries management: Example of the Capbreton canyon,southern Bay of Biscay ArchiMer
Sanchez, Florence; Morandeau, Gilles; Bru, Noelle; Lissardy, Muriel.
Marine Protected Areas (MPAs) are generally considered as one of the most important tools, among the many regulations, designed to preserve marine resources as well as enhance fisheries. In the southern Bay of Biscay, local French fishermen requested creation of a restricted area to help settle disputes between the various métiers operating there. This restricted area, which lies mainly in French waters, covers part of a deep submarine canyon off the French and Spanish coasts, known to have a large population of mature hake. This study aims to better understand the effects of a restricted area upon French fleets operating there, particularly upon three main métiers – longliners, gillnetters and trawlers. The study area includes three ICES statistical...

Le présent document concerne le résultat des travaux confiés à l'IFREMER et à l'UPPA sur l'usage "pêche professionnelle". Il s'appuie sur des observations en mer à bord de navires de pêche (IFREMER/LRHA) et sur des enquêtes de perception de la démarche Natura 2000 (UPPA/SET) auprès de pêcheurs professionnels et de leurs représentants. Elles concernent le site Natura 2000 « Côte basque rocheuse et extension au large » (FR7200813).

Campagne d'évaluation du stock de palourdes du bassin d'Arcachon - Année 2006 ArchiMer
Caill-milly, Nathalie; Duclercq, Benoit; Morandeau, Gilles.
Between 1980 and 1986, some Arcachon oyster farmers took up breeding the Japanese clam on the foreshore (Robert et Deltreil, 1990). This production was short lived. The steep fall in prices due to economic competition from Spain, Portugal, Italy and Tunisia, predator action such as the trigger fish (Popovsky et al., 1999), added to the significant amount of mortality that occurred in the summer and autumn of 1992 that affected two-thirds of the total stock, led to clam farming being abandoned at the end of the 1980s. In the Arcachon basin, the Japanese clam (Ruditapes philippinarum) population, now natural to the area, has found favourable conditions for development and is expanding rapidly there. This species has been supplanting the local species...

Characterization and standardization of the Atlantic albacore French pelagic trawl fishery ArchiMer
Nikolic, Natacha; Lauretta, Matthew; Patucca, Audrey; Morandeau, Gilles.
We compiled and analysed logbook data from the French trawl albacore fishery covering the period 1991–2015. The dataset comprised catch and effort data for the French fleet operating in the Bay of Biscay and Celtic Sea, as well as spatiotemporal and gear characteristics. Generalized linear modelling was used to model spatial, seasonal, environmental, and gear covariates of fleet CPUE rates. A long-term index of relative abundance is provided that can be integrated into the stock assessment of North Atlantic albacore. The analysis revealed higher albacore CPUE associated with relatively low sea surface temperature and distinct seasonal effects. The derived abundance trend for the French trawl fishery agreed with the estimated time series of stock abundance...

Characterizing catches taken by different gears as a step towards evaluating fishing pressure on fish communities ArchiMer
Fauconnet, Laurence; Trenkel, Verena M.; Morandeau, Gilles; Caill-milly, Nathalie; Rochet, Marie-joelle.
To implement an ecosystem approach to fisheries management, there is a need to characterize the total pressure exerted by fisheries at the community level. French onboard observer data were used to derive catch metrics and compare fishing distribution across community components between two sites in the Southern Bay of Biscay. Sample-based rarefaction curves were used to standardize metrics across different active and passive gears, and correct for sample size differences. Six metrics for species, length and functional catch composition were tested. Length and functional metrics were found the most relevant metrics to highlight differences in catches between gears, sites, and gear-site interactions. Significant differences were found between gears, mainly...

Espèces inhabituelles capturées dans le sud du golfe de Gascogne. Synthèse 1997-2012 ArchiMer
De Casamajor, Marie-noelle; Morandeau, Gilles.
This report summarise the ichthyological data collected by the laboratory on unusual catches of the Aquitain coast. They are intended to fishermen who transmit information and are also displayed in the fishing market to allow feedback to the profession. Species are classified according to their ecological affinity and their families in a second way. The unusual nature of the capture is also mentioned if it is a first catch of the specie, if it is observed occasionally or more regularly in the landings. A review is made after 15 years of collecting information and perspectives it would be interesting to develop are reported .

Essais de casiers à langoustines dans la fosse de Capbreton ArchiMer
Morandeau, Gilles; Morandeau, Fabien; Duclercq, Benoit.
Scampi (Nephrops norvegicus) is traditionally fished with bottom trawls on muddy grounds. Some trawlers from Bayonne fish it from May to August in the south of the Bay of Biscay. The Capbreton area is partly forbidden to trawling and net fishing (see appendix 1) In spring and summer, it is frequented by a fleet of about fifteen vessels, among which are some lining vessels, fishing hake, and a few pot vessels, targeting crabs. Some of these vessels could be interested in using scampi traps in this area in order to be more versatile and, to a certain extent, to diminish their economical vulnerability through a diversification of the revenues generated by another high market value species. Ifremer offered to assess a new tool: scampi trap, on the Basque and...

Étude prospective de l'exploitation des coquillages au large des côtes d'Aquitaine Volet : Ressources et première approche économique ArchiMer
Caill-milly, Nathalie; Duclercq, Benoit; Morandeau, Gilles; De Casamajor, Marie-noelle.
Introduction: With the objective of diversifying current fishing and at the request of professionals in Aquitaine, the Regional Commission of Maritime Fishing and Marine Breeding (CRPMEM) of Aquitaine has started a discussion about the possibilities of opening a shellfishery. In the context of this course of action, and because of the absence of information on the presence and size of the resource, the CRPMEM of Aquitaine asked IFREMER's Halieutic Resources Laboratory of Aquitaine (LRHA) for assistance in acquiring information on the subject. At the same time, a prospective analysis study of the exploitation of shellfish off the coast of Aquitaine—regulation and business section—was performed by the CRPMEM of Aquitaine (Coiffec, 2006). At that same time,...

Guidelines for the definition of operational management units ArchiMer
Uriarte, Andres; Zarauz, Lucia; Aranda, Martin; Santurtun, Marina; Iriondo, Ane; Berthou, Patrick; Castro, Jose; Delayat, Stephanie; Falcon, Jesus; Garcia, Javier; Gaspar, Miguel; Gonzalez, J.f.; Jimenez, Sebastian; Lordan, Colm; Morandeau, Gilles; Sanchez, Florence; Santamaria, Maria Theresa; Villegas, Noemi.
The objective of fisheries management is the sustainable exploitation of the fish resources over the extent of their spatial distribution. Along with the Common Fisheries Policy (CFP) objectives, the socio-economic viability of the fisheries exploiting the resource is also to be achieved. To reach these aims, managers need to define the management units they are going to work with. For the purpose of GEPETO project, we define a management unit (MU) as the set of fishing fleets exploiting a common pool of fish resources with strong spatial overlapping and sharing of habitats, which make them being typically fished together. In other words, a MU is the set of fishing fleets exploiting a common fish community over their spatial distribution. MUs have to be...
