Evidence of a relationship between weight and total length of marine fish in the North-eastern Atlantic Ocean: physiological, spatial and temporal variations ArchiMer
Mahe, Kelig; Bellamy, Elise; Delpech, Jean-paul; Lazard, Coline; Salaun, Michele; Verin, Yves; Coppin, Franck; Travers-trolet, Morgane.
Weight–Body Length relationships (WLR) of 45 fish species (37 Actinopterygii and eight Elasmobranchii) were investigated. A total of 31,167 individuals were caught and their biological parameters measured during the four quarters from 2013 to 2015, on five scientific surveys sampling the North-eastern Atlantic Ocean from the North Sea to the Bay of Biscay (ICES Divisions IVb, IVc, VIId, VIIe, VIIg, VIIh, VIIj, VIIIa and VIIIb). Among 45 tested species, all showed a significant correlation between total length (L) and total weight (W). The influence of sex on WLR was estimated for 39 species and presented a significant sexual dimorphism for 18 species. Condition factor (K) of females was always higher than for males. Moreover, a spatial effect on the WLR...

Le laboratoire Ressources halieutiques du centre de Boulogne ArchiMer
Delpech, Jean-paul.
Longtemps, le port de Boulogne/Mer a, sans concurrence, été le premier port de pêche fraîche de France. Se disputant cette primauté avec Lorient depuis les années 80, il a repris cette place au début des années 90 et ne l'a plus quitté depuis. L'Office des pêches puis l'ISTPM et maintenant l'IFREMER y ont donc logiquement maintenu un laboratoire de recherches halieutiques depuis 1883.

Possibilités d'exploitation de matériaux marins sur les façades maritimes "Manche-Est" et "Loire-Gironde". Synthèse ArchiMer
Augris, Claude; Delpech, Jean-paul.
A la demande du Ministère de l'Industrie, une étude conjointe Ifremer - BRGM a été menée de 2006 à 2009 pour évaluer les enjeux environnementaux et les usages existants sur les secteurs reconnus comme offrant des ressources en matériaux marins. Cette première étude a porté sur les façades "Manche Est" et "Loire-Gironde". Ce rapport fait la synthèse des connaissances acquises dans les domaines suivants: i) géologie-ressources; ii) ressources et activités halieutiques; environnement, zones protégées et réglementées, système d'information géographique (SIG) final.

Integration and sharing of data on marine ecosystems. ArchiMer
Auber, Arnaud; Delpech, Jean-paul.
Integration and data sharing on marine ecosystem constitute two major contributors to ecosystem management. In this report, we present the different methods that have been used to integrate and share data in the context of Interreg IVA France (Channel) – England projects. Identification of limits and barriers encountered within these projects may help to improve our capacity to lead future projects, notably those involved in marine ecosystem management.

Essais d'un chalut avec fenêtre à mailles carrées en Mer du Nord ArchiMer
Brabant, Jean-claude; Delpech, Jean-paul; Dufour, Jean-louis; Garren, Francois.
The fragile state of the cod stock in the North Sea and Western Scotland has made the European Commission take a certain amount of measures to reconstitute these stocks since the end of 2001. One of those measures consisted of improving the selection capacity of the bottom otter trawls in order to reduce the capture of juveniles, through a compulsory selection device of square mesh panel type. In this context, the Regional Marine Fisheries Committee of Nord/Pas-de-Calais/Picardie, which is against any increase of the mesh size but agrees with the adoption of a new selection device, decided to organize technical trials along with the IFREMER, so as to evaluate its efficiency. A square mesh panel system was tested in multispecific fisheries in the southern...

Amélioration de la sélectivité des chalutiers Pêcherie multispécifique – Manche - Mer du Nord (selecmer) ArchiMer
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...

Catalogue international des activités des flottilles de Manche, approche des interactions techniques ArchiMer

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 fleet 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 the resources (in preparation). The concept of a métier 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 métiers were identified during 1989-90. For each métier we give a brief description of the catching gear, the target species and most usual by-catch, the...

Etude d'impact du rejet des eaux d'exhaure du tunnel sur l'environnement marin ArchiMer
Monbet, Yves; Delpech, Jean-paul; Le Hir, Pierre.
En 1983, plus de 20 millions de voyageurs et près de 20 millions de tonnes de marchandises ont traversé la Manche ou la Mer du Nord entre la Grande-Bretagne et le continent. Ces échanges sont trois fois supérieurs à ceux enregistrés en 1970, ce qui représente une augmentation annuelle de l'ordre de 10 %. Les prévisions les plus réalistes tablent actuellement sur une augmentation moyenne légèrement supérieure à 4 % par an d'ici l'an 2000, ce qui équivaut à plus que doubler à cette date le trafic actuel. Pour répondre à une telle demande, il a été nécessaire d'envisager différentes solutions permettant de faire face à l'augmentation prévue.

Remblaiement de la zone du terminal de la liaison transManche - Effet des dragages et des rejets d'eaux issus des remblais sur la flore, la faune marine et les activités halieutiques ArchiMer
Monbet, Yves; Delpech, Jean-paul.
Le lien fixe transmanche dont la mise en service est prévue pour l'année 1993 nécessite la construction de deux terminaux, l'un situé en Grande-Bretagne et le second en France comportant notamment des voies d'accès, des aires d'accueil, des quais ainsi que des bâtiments administratifs et des ateliers d'entretien (figure 1). De côté français, les ouvrages du terminal se répartiront sur une surface approximative de 50 ha et seront composés essentiellement par six grandes zones (figure 2) : - accès routiers et échangeurs, - terminal tourisme, - terminal commercial, - quais, - zone de maintenance, - boucle ferroviaire. Compte tenu de la géomorphologie des terrains en place, la réalisation de ces zones d'activités nécessite d'importants mouvements de terrains....

GHYDRO: Methodology guide for assessment of environmental impacts of tidal stream energy technologies at sea ArchiMer
Lejart, Morgane; Auvray, Cedric; Barillier, Agnes; Cadiou, Bernard; Carlier, Antoine; Delpech, Jean-paul; Folegot, Thomas; Giry, Cyril; Loaec, Jean-marie; Martinez, Ludivine; Prevot, Jehanne.
The objective of GHYDRO, a France Energies Marines project, is to draw up a methodology guide that provide stakeholders in tidal stream energy projects with decision-making help for the environmental integration of generators and tidal farms. The methodological guide currently represents a summary of the recommendations concerning the diverse physical parameters and biological compartments of the ecosystems that are potentially affected. The physical and biological compartments of the marine ecosystems have been addressed separately in the guide, in order to propose methodologies adapted to each one, in relation to the establishment of the initial state, the characterisation of the potential impacts and the environmental monitoring. To bring together the...
