Aires marines protégées et récifs artificiels : méthodes d'évaluation, protocoles expérimentaux et indicateurs ArchiMer
Claudet, Joachim.
Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers. It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced...

Caractéristiques de dragues et pêcheries ArchiMer
Pitel, Mathilde; Berthou, Patrick; Fifas, Spyros.
Basically, a dredge is a bottom-towed gear and consists of a metal frame with a blade or teeth, to dig into the sediment and extract the shelled molluscs, and a mesh bag to collect the catch. Whereas hand dredging is observed on some intertidal beds (Donax trunculus in France), the use of dredge generally needs a fishing boat. There is a great diversity of dredge types, with specific designs used to target different species in particular beds: Manual dredges for Donax (Donax trunculus), Warty venus (Venus verrucosa) and clams (Venerupis pulastra, Ruditapes sp) Dredges for King scallops (Pecten maximus) Dredges for Warty venus (Venus verrucosa) Dredge for Queen scallops (black and white, Chlamys varia and Chlamys opercularia) Dredges for small...

De la biodiversité aux biotechnologies bleues : la caractérisation et l'exploitation des ressources marines sont-elles compatibles? ArchiMer
Goulletquer, Philippe.
L’exploitation de la biodiversité marine, notamment via les biotechnologies, offre un réel potentiel de valorisation comme le démontre l'accélération des dépôts de brevets utilisant des substances actives marines. Ce point est renforcé par les particularités uniques de la biodiversité marine. Le défi à l’heure actuelle est de définir les conditions d’exploitation durable dans un contexte de connaissances limitées des écosystèmes concernés. Si les activités actuelles tendent à privilégier la préservation de l’environnement marin, le développement de connaissances et la levée de verrous technologiques permettront probablement à l’avenir d’identifier les ressources d’intérêt puis de les exploiter par des approches industrielles innovantes (e.g.,...

Diagnostic technico-économique et aide à la gestion d'entreprise en aquaculture ArchiMer
Calleja, P; Paquotte, Philippe.
Formal accounting sheets usually turn out being unappropriate to identify the technical or managerial elements causing the financial situation of an enterprise and to imagine the future of that enterprise as well. That is the reason why, as it has been widely developed in agriculture, a technico-economic approach linking the physical flows related to the activity of the enterprise and the resulting financial flows should be a better answer to the need of vigilance on husbandery practices and to the need of projection in the future. The realization of a computerized simulation tool taking into account some relevant technical, biological and economic criteria makes it possible to assess the consequences of investment decisions on the cash-flow and on the...

Port activities require continuous or occasional dredging of considerable quantities of sediments : approximately 50 million m3 along the French coastline. A large proportion of the dredgings is authorized for dumping at sea in geographically delimited areas and following an impact evaluation of their potential harmfulness to the marine environment. The environmental risks assessment linked to dredging operations relies on knowledge related to several scientific disciplines contributing to changes in the regulations. This work, intended both for managers and for environmental scientists and engineers, is designed to take stock of the current state-of-the-art in the field of sediment contamination and related ecotoxicological hazards, along with a review of...

Dynamique des pêcheries traditionnelles d'anchois, de calmars et de poulpes du Sud-Ouest de Madagascar : utilisation d'outils océanographiques pour la gestion des ressources ArchiMer
Bemiasa, John.
Anchovy (Stolephorus indicus), squid (Loligo sp.) and octopus (Octopus cyanea) are among the main exploited halieutic resources in the south western region of Madagascar. Important year to year changes of their abundance (e.g. anchovy) could have drastic consequences on catches as well as for the economy of the local communities. Yearly environmental changes analysis on enrichment process in upwelling area (Chl-a), sea surface temperature, winds permitted to explain annual and seasonal variability of anchovy, squid and octopus abundance index as well as their seasonal reproduction strategy. Seasonally environmental cycle is taken in account by species for their reproduction strategy development. Results from this study show the first idea of factors and...

Dynamique des populations de palourdes japonaises (Ruditapes philippinarum) dans le bassin d'Arcachon : conséquences sur la gestion des populations exploitées ArchiMer
Dang, Cecile.
The Manila clam Ruditapes philippinarum was introduced into Arcachon Bay at the beginning of the 1980s for aquaculture purposes. It rapidly naturalized in all intertidal flats of the lagoon. Nowadays, Arcachon Bay ranks at the first French place in terms of exploitable stock. However, recent stock assessments have shown an unbalance size structure with a deficit in juvenile and adult clams (> 38 mm shell length). These alarming patterns asked many questions on the sustainability of Manila clam populations within Arcachon Bay and have motivated the present thesis. This study aimed to better understand the population dynamics of this species and also some factors controlling this dynamic. The final objective was to improve the Manila clam fishing...

Flux et usages de l'eau de mer dans les marais salés endigués Charentais : Cas du marais salé endigué de l'île de Ré ArchiMer
Paticat, Francois.
The aim of the study is to determine how seawater is used in Ré island marine ponds (Charente-Maritime, France). Thus, we assessed the ecosystem functioning, estimated its historical evolution and determined the most suitable ways to improve current management processes. The knowledge of seawater management is essential to ensure wetland future and meet the numerous interests of wetland stakeholders, especially in term of seawater sharing. Consequently, it is necessary to consider the Ré island marine embanked wetland through its natural as well as human characteristics. Our work followed two research axes. First, a survey and a description of wetland activities were realized through their management types and their water use features, knowing that human...

La gestion des ressources et des territoires : Application à la mise en oeuvre de projets de valorisation de sous-produits de poisson ArchiMer
Penven, Anais.
Beyond the technical and technological advances in the conversion of marine by-products into useful products, the territorial, economic, social, political and environmental parameters, which govern all forms of approaches for fish by-products upgrading, must be taken in account. This is essential to understand why and how bioconversion technologies are applicable. The fishery sector is facing several issues such as fish stocks weakening, recourse to imports, aquaculture rising or consumers behaviors which complicate the approach of fish by-products upgrading as it is linked to the raw material processing. Thanks to some projects addressed this thematic in recent years, several quantitative and qualitative data about by-products deposits are available....

Le développement durable des filières de la conchyliculture et de la pêche dans les Pertuis Charentais: évaluation et gestion du risque sanitaire lié à l'environnement ArchiMer
Bordage, Laëtitia.
Ce travail effectué sous la responsabilité de Gérard Thomas, s'est déroulé en deux grandes phases. Une première phase a été de rechercher la documentation relative à la conchyliculture et aux normes sanitaires. Ces recherches se sont principalement déroulées aux Archives Départementales de la Charente-Maritime, pour l'aspect historique, à la Bibliothèque Universitaire de La Rochelle et sur Internet, pour les textes juridiques relatifs aux normes sanitaires. Ensuite, il a fallu analyser l'ensemble de ces documents pour en ressortir une synthèse. Dans un second temps, il s'agissait de prendre contact avec les différents organismes intervenant dans la gestion du risque sanitaire pour la filière conchylicole. Pour cela, des rencontres des représentants des...

Le merlu europeen (Merluccius merluccius L.). Bilan des connaissances biologiques. Evolution de l'exploitation. Evaluations des stocks et mesures de gestion ArchiMer
Guichet, Roger.
European hake is one of the most important commercial species of the North East Atlantic. Its biology is quite well known in spite of age reading problems. This report provides a review of the state of knowledge based on updated data, specially for parameters used in the working groups in charge of stocks assessments. The fisheries for hake are essentially sequential. In recent years fishing mortalities have been moderate and the over exploitation of the stocks is due to the excessive catches of young fish and to the fishing pattern of some fleets. The result of this inappropriate exploitation pattern is dangerous with a decrease of the spawning stock biomass and recrutrnent for the two stocks.

Les enjeux de la recherche en économie maritime ArchiMer
Abric, M; Weber, Jacques.
In September 1989, Mr Pierre Papon, Chairman of the IFREMER, expressed his wish for a study on the issues of research in marine economy. Carried out under the direction of Jacques Weber, this document is the result of this study. Dealing with marine economy equals, mutatis mutandis, dealing with terrestrial economy: the uniqueness of the subject, economy, as that of the marine element, hides a wide heterogeneity and a multiplicity of research questions. This is the reason why eight different fields were chosen to be investigated. It was decided to take an inventory, for each field, of all the specialised research centres, and to interview their directors or some specialists. Interviews were thus carried out by sector.

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...

Rapport sur l'exercice de la pêche dans la zone côtière de la France ArchiMer
Bolopion, Jacques; Forest, Andre; Sourd, Louis-julien.
The maritime fisheries and mariculture guidance law passed in 1997 specifies that with the perspective of renegotiation of the common fisheries policy in 2002, a report on the special conditions of inshore fisheries be drawn up by the Government. To do so, the Minister of Agriculture and Fisheries entrusted this task to three experts, who are the authors of this report. In accordance with their remit, the situation of fisheries in territorial waters and estuaries of metropolitan France and the four DOM overseas departments ( counties) was examined, in the framework of meetings with professional fishermen, administrations, elected officials and scientific organisations. The first part situates fishing activities in coastal areas within the overall context...

Relations entre l’état d’une ressource et son exploitation via la compréhension et la formalisation des interactions de socio-écosystèmes. Application à la palourde japonaise (Venerupis philippinarum) du bassin d’Arcachon. ArchiMer
Caill-milly, Nathalie.
Significant component of the marine benthic ecosystem, exploited bivalves are mainly located inside the coastal area, which temporal and spatial features generate natural population fluctuations and contribute to considerable biomass and demographic structure changes added to anthropogenic activities’ effects (fishing, pollution,…). Understanding of the relationships between the species, its environment and its exploitation is crucial and their formalization, including for management purposes, requires development of mathematical models that aim at describing the functioning of the system, to explain the observed phenomenon in terms of cause and effect or predict effects of new causes. Originating from venerid culture trials carried out in France in the...

Simulation de la dynamique de pêcherie : modélisation, complexité et incertitude ArchiMer
Mahevas, Stephanie.
Fisheries are defined by a set of fishermen and of marine populations impacting each other in a spatial-limited marine ecosystem. Within the over-exploitation context and according to ratified sustainable management objectives, my research has been focused on the development and a caution use of a mechanistic model describing fisheries dynamics. This model allows for integrating existing knowledge of fisheries. It aims at improving the understanding of fisheries functioning and at investigating the impact of fishing regulations on fisheries dynamics. This modelling exercise has supported many methodological developments for its parametrisation and its use in uncertainty context. Concerned with promoting a correct use of a complex model (that ambiguity link...
