A classification scheme for deep seafloor habitats ArchiMer
Greene, Hg; Yoklavich, Mm; Starr, Rm; O'Connell, Vm; Wakefield, Ww; Sullivan, De; Mcrea, Je; Cailliet, Gm.
A standard, universally useful classification scheme for deepwater habitats needs to be established so that descriptions of these habitats can be accurately and efficiently applied among scientific disciplines. In recent years many marine benthic habitats in deep water have been described using geophysical and biological data. These descriptions can vary from one investigator to another, which makes it difficult to compare habitats and associated biological assemblages among geographic regions. Using geophysical data collected with a variety of remote sensor systems and in situ biological and geologic observations, we have constructed a classification scheme that can be used in describing marine benthic habitats in deep water.

Catalogue international des activités des flottilles de Manche, approche des interactions techniques ArchiMer
Tetard, A; Boon, M; Bennett, D; Berthou, Patrick; Bossy, P; Casey, J.
This work is the result of collaboration between the English, French, Channel Isles and Belgian laboratories which are involved in a study of the English Channel. Its subject is the activities of fleets and their interactions, and it complements other work on the biogeographical identification of Channel fish and shellfish stocks (published), and on modelling the fleets' interactions as they exploit theresources (in preparation). The concept of a metier is defined as being the use of one fishing gear to catch one or several species targeted during a particular season in a given area. On this basis, 74 metiers were identified during 1989-90. For each metier we give a brief description of the catching gear, the target species and most usual by-catch, the...

Des modèles et des indicateurs pour évaluer la performance des Aires Marines Protégées pour la gestion des zones côtières. Application à la Réserve Naturelle des Bouches de Bonifacio ArchiMer
Rocklin, Delphine.
These last decades have been characterized by a great development of fishing techniques, contributing to the overexploitation of numerous marine fish stocks. In order to limit this collapse and to restore impacted communities, the implementation of management measures was necessary. Marine Protected Areas (MPAs), initially developed to protect remarkable habitats and associated biodiversity, are more and more used as a tool for spatial management of fishing activities, by adult export and/or larvae migrations from protected zones to surrounding fisheries. The aim of this PhD was to use indicators and predictive models for evaluating the impact of the Bonifacio Strait Natural Reserve (Corsica) implementation on fish communities and the benefits of such...

Economics and biology used in fisheries research or when social and natural sciences try to depict together the object of their research ArchiMer
Catanzano, Joseph; Mesnil, Benoit.
Fisheries can be characterized as a network of interactions between natural and social systems, and thus should be viewed as complex, dynamic systems. Due to the multiplicity of components and processes, the involvement of various disciplines is required to understand the inter-relationships within and between the systems, and more so to adequately address management issues that typically affect several elements in the systems. To be successful, multidisciplinary approaches require mutual understanding of the perspectives, concepts, vocabulary and methods held by various disciplines, and agreement on the objects to be studied in common. In that spirit, at framework is suggested whereby fisheries systems are decomposed into related sub-systems that can be...

Impact des mesures de gestion sur la dynamique de la pêcherie pélagique du golfe de Gascogne : Quelles certitudes ? Quels descripteurs ? ArchiMer
Lehuta, Sigrid.
Quantitative evaluations of management measure impact on resource and fleet viability are required to provide diagnostics and feed decision process. Fisheries are complex systems where numerous dynamics interact at various spatial and temporal scales. This complexity and the difficulty to observe marine systems are responsible for the high uncertainty surrounding fishery functioning that makes it hard to identify adequate management measures. The increasing consideration of uncertainties in diagnostics argues in favor of robust management measures rather than optimal management measures. Identifying robust management measures requires the development of models that account for complexity and uncertainty in the description and prediction of management...

Les pêcheries mixtes de langoustine et merlu du Golfe de Gascogne, modélisation bio-économique et simulation des procédures de gestion ArchiMer
Charuau, Anatole.
Fishing crayfish on the gulf's mudflats is a traditional business practised by 450 boats of 12 to 18 metres in length and employs 2,500 sailors. In the north of the gulf, this activity is exclusive, in the south, immature hake are also caught, because the crayfish areas coincide, in part, with the nurseries of the northern stock of this species. Management of these fisheries, called mixed, of crayfish and hake is one of the greatest problems of the Gulf of Gascony. All assessments tend to show the responsibility of the crayfish boats in the future of the hake stock. The solution is likely to pass through a generalised increase of the 80 mm meshing that would lead, eventually, the hake stock yield to its maximum, but would eliminate a great many trades...
