-The eastern English Channel, the narrow channel of water separating northern France and southeast England is an area of intense human use of the array of resources concentrated into its relative small area. The vulnerability of living resources and their habitats brought together French and British maritime experts within a common project (called CHARM): to create an atlas of marine resource habitats in the eastern English Channel so as to provide planners and decision-makers with the necessary information to help managing the use of its living and non-living resources. This multidisciplinary and richly illustrated atlas provides abundant information on the legal framework and physical environment; benthic invertebrates, fish and their habitats; fishing activities; and a first attempt at developing a trophic network model (using ECOPATH software) and a marine conservation planning exercise (using MARXAN software, at a spatial resolution of 25 km 2 ). Although most of the data used were collected elsewhere, some were collected especially for the project. Similarly, most of the analyses performed on the data where entirely original for this geographical area. The CHARM atlas has significantly improved the knowledge about the eastern Channel while contributing to the recognition that such holistic or multidisciplinary approaches to exploited marine systems are necessary to efficiently and durably manage their resources use. Key words: Eastern English ChannelRésumé -La Manche orientale, ce bras de mer qui sépare l'Angleterre de la France, est une zone très riche d'un point de vue écologique et soumise à une forte utilisation anthropique d'une gamme de ressources concentrées sur une superficie relativement faible. La fragilité des ressources marines vivantes et leurs habitats a rassemblé des experts maritimes français et britanniques autour d'un projet commun (nommé CHARM) dans le but de réaliser un atlas des habitats des ressources marines de la Manche orientale. Cet atlas contient les informations nécessaires aux planificateurs et décideurs pour une meilleure gestion des ressources marines, vivantes ou non. Dans ce document pluridisciplinaire, richement illustré, on peut trouver des informations sur le cadre juridique et l'environnement, les invertébrés benthiques, les poissons et leurs habitats ; les activités de pêche ; et également sur le développement d'un modèle de réseau trophique a Corresponding author: andre.carpentier@ifremer.frArticle published by EDP Sciences 500 C.S.

“…The following major operations were conducted ( Fig. 1): fish echo-integration and mid-water identification trawl hauls were undertaken during day time, a continuous underway fish egg sampler (CUFES, Checkley et al, 1997) was operated during night and day, and CTD casts were performed during night time, together with the collection of water and plankton at CTD hydroplankton stations. The survey was designed with parallel transects spaced regularly crossing the entire width of the shelf from 44°N (Gouf de Cap Breton) to 48°N (Pointe du Ratz).…”

SUMMARY:The spatial pattern in hydro-plankton and fish distributions and their relationship were analysed based on the spring 2000 fisheries acoustic survey. The importance of this survey was that it was a multi-disciplinary platform which collected an extensive set of parameters in the hydro-plankton leading to a potentially finer description of hydro-plankton conditions and fish habitats. More than 50 variables were measured on a grid of stations, in four compartments of the ecosystem: hydrology, nutrients, primary producers and meso-zooplankton. First, a joint analysis of all hydro-plankton compartments was performed using multiple factor analysis (MFA). The method was used to estimate a compromise factorial space common to all compartments in which the stations were grouped by hierarchical clustering. The groups were represented spatially and a strong spatial pattern was evidenced. The fish and their spawned eggs were sampled along transect lines using acoustics and CUFES (continuous underway fish egg samplers). The distribution of the fish and their eggs was analysed in relation to the hydro-plankton groups of stations and difference in fish density across hydro-plankton conditions was tested by a pair-wise multiple comparison procedure. Anchovy was associated with a lesser number of hydro-plankton conditions than sardine. Eggs of both species were also associated with a lesser number of conditions than the fish. Finally, the gain provided by using the extensive set of hydro-plankton parameters for mapping large-scale hydro-plankton conditions was analysed in comparison with the situation in which a small set of parameters was available. The extensive set of parameters allowed more hydro-plankton conditions to be identified but only in the coastal area and not on the shelf. Size fractionated chlorophyll was determinant for tracking river plume hydro-plankton condition. However, the fish did not respond to the variety of the coastal hydro-plankton conditions. Keywords: spatial pattern, multiple factor analysis, habitats, hydro-plankton, fish-environment relationship.

Fisheries oceanography and the ecology of early life histories of fishes: a perspective over fifty years

SUMMARY: Fisheries oceanography can be defined as the study of the ecology of fishes in the ocean: so defined, it comprises study at all levels of ecological organization-organisms, populations, communities, and ecosystems. The early life history of fishes plays out at each of these levels of organization. A paradigm developed by Johan Hjort at the turn of the twentieth century, along with postulates by Hjort and many of his colleagues that followed, came to guide much of fisheries oceanography through the ensuing hundred years. Research themes that address these postulates can be roughly partitioned as the study of the physiological ecology of the eggs and larvae of fishes in the sea, and the study of the abundance and distribution of fish propagules. Using case studies of organisms and physical processes, considerable progress has been made in understanding the causes of variation in population recruitment, defined either by stage-based models and simulated by individual-based models. Some of this progress has been published in Scientia Marina, or its predecessor Investigación Pesquera. The causes of variation, however, are interactive and operative at differing, yet often overlapping, spatial and temporal scales. Difficulty in matching spatial scales that typically differ by an order of magnitude or more, will continue to trouble the resolution of causes of population recruitment. Moreover, study of the causes of variation in recruitment has not led to predictive power at an annual scale. Prediction at a decadal scale, using community (or more appropriately larval fish assemblages) and ecosystem level dynamics, is more hopeful. -La oceanografía pesquera puede ser definida como la ecología de los peces en el océano: definida de este modo, comprende el estudio a todos los niveles de organización ecológica: organismos, poblaciones, comunidades y ecosistemas. Los primeros estadios de desarrollo de los peces intervienen en cada uno de estos niveles de organización. El paradigma desarrollado por Johan Hjort a principio de siglo veinte, junto con postulados posteriores del propio Hjort y muchos de sus colegas, han servido de guía de la oceanografía pesquera de los siguientes cien años. Los temas de investigación a que conducen estos postulados pueden ser fundamentalmente divididos en el estudio de la ecología fisioló-gica de los huevos y larvas de peces en el mar y el estudio de la distribución y abundancia de los propágulos. Utilizando el estudio de casos particulares de organismos, se han conseguido considerables progresos en la comprensión de las causas de variación en el reclutamiento de las poblaciones, definido ya sea por los modelos basados en el estadio de desarrollo o en simulaciones basadas en el individuo. Algunos de estos avances han sido publicados en Scientia Marina, o en su predecesora Investigación Pesquera. No obstante, las causas de variación son interactivas y operativas a escalas espaciales y temporales distintas, o incluso solapadas. La dificultad para ajustar las escalas espaciales que típicame...
