Depuis une vingtaine d'années, l'Ifremer organise des campagnes de pêche scientifique en mer du Nord, Manche, Atlantique et Méditerranée concernant les ressources pélagiques, démersales et benthiques. L'objectif prioritaire est de produire des indices d'abondance des principales espèces commerciales. Elles recueillent également des données sur les espèces capturées non commerciales. Les campagnes sont réalisées selon des plans d'échantillonnage standardisés. L'engin de pêche et son gréement, la position des stations, le tri des captures, les prélèvements biologiques suivent des protocoles fixés. Chaque zone étudiée est découpée en fonction de la profondeur, de la latitude ou d'autres critères. L'échantillonnage prévoit un nombre de traits de chalut...

The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing. [...] After a series of "Understanding keys" aimed at helping the reader understand the methodology and...

Le comportement agrégatif des dorades coryphènes (Coryphaena hippurus) autour des objets flottants ArchiMer
Taquet, Marc.
The aggregative behaviour of the dolphinfish (Coryphaena hippurus) is studied in order to improve our knowledge of the mechanism involved in the association of this species with the floating objects and to evaluate its potential impact in term of exploitation, targeted or not. This PhD thesis is composed of four chapters. Through an extensive analyze of the literature, the first chapter takes stock of the present knowledge on the FADs, on the aggregative behaviour of pelagic fish and on the dolphinfish. The second chapter deals specifically with the aggregative behaviour of the dolphinfish by the way of acoustic tagging of fish carry out during offshore campaigns around drifting FADs. The feeding habits of the dolphinfish around FADs are the main purpose...
