Inter-specific and ontogenic differences in delta C-13 and delta N-15 values and Hg and Cd concentrations in cephalopods
Auteur(s) : Chouvelon, Tiphaine Spitz, Jerome Cherel, Y. Caurant, Florence Sirmel, R. Mendez-fernandez, P. Bustamante, Paco

Éditeur(s) : Inter-research
Résumé : Chemical tracers (e. g. stable isotopes or trace metals) are increasingly used to study trophic ecology and feeding habits of marine organisms and various factors can affect their values. The aim of the present study was to provide information on ontogenic effects on stable carbon and nitrogen values (delta C-13 and delta N-15) and on cadmium (Cd) and mercury (Hg) concentrations in 5 cephalopod species from the Bay of Biscay (North-East Atlantic Ocean). To this end, individuals belonging to 3 species showing the widest range of sizes were analysed for muscle delta C-13 and delta N-15 values and muscle Hg, and digestive gland Cd concentrations. Results showed that stable isotope ratios allowed discrimination of specific feeding strategies during ontogenesis. Segregation between 5 cephalopod species in terms of trophic ecology was also evidenced (different isotopic niches). In contrast, Hg concentrations varied over the same order of magnitude in these 5 cephalopod species, despite higher levels in the benthic octopus Eledone cirrhosa. Consistently, Hg concentrations followed the same ontogenic pattern and increased with increasing body size/age of cephalopods. Finally, Cd concentrations varied over 3 orders of magnitude among the 5 species. Despite possible effects of physiology in terms of metal bioaccumulation, Cd concentrations were likely to reflect specific feeding preferences or feeding zones and ontogenic variability within a single species. Thus, ontogenic effects have to be taken into account when stable isotope ratios of carbon and nitrogen or trace metals are used as ecological tracers; the best recommendation being to focus on a given class age.

Le comportement agrégatif des dorades coryphènes (Coryphaena hippurus) autour des objets flottants
Auteur(s) : Taquet, Marc

Éditeur(s) : Université Paris 6
Résumé : 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 of the third chapter. It is studied by the way of two complementary methods : stomach contains analysis of dolphinfish aggregated around several types of floating objects and underwater inventory of the marine fauna under these floating objects. Finally, the fourth and last chapter sums all the results and suggests a theory to explain the aggregative behaviour of the dolphinfish. We also try to estimate the possible consequences of this behaviour on the abundance and on the distribution of this species on a larger scale.
Le comportement agrégatif de la dorade coryphène (Coryphaena hippurus) est étudié dans le but de mieux comprendre le déterminisme de l'association de cette espèce avec les objets flottants et d'en évaluer les impacts potentiels en terme de sensibilité à l'exploitation halieutique, qu'elle soit ciblée ou non. Ce mémoire de thèse est organisé en quatre chapitres. A travers une analyse approfondie de la bibliographie, le premier chapitre présente un bilan des connaissances actuelles sur les DCP, l'agrégation des poissons pélagiques et la dorade coryphène. Le second chapitre traite plus spécifiquement du comportement agrégatif de la dorade coryphène. Il a été abordé à l'aide de marquages électroniques réalisés au cours de campagnes hauturières autour de DCP dérivants. Le comportement trophique de la dorade coryphène fait l'objet du troisième chapitre. Il est abordé par l'utilisation conjointe de deux méthodes d'investigation : l'analyse des contenus stomacaux de dorades coryphènes agrégées sous divers types d'objets flottants et la réalisation d'inventaires faunistiques sous-marins autour de ces objets flottants. Enfin, le quatrième et dernier chapitre synthétise l'ensemble des résultats obtenus, propose une théorie du comportement agrégatif de la dorade coryphène et tente d'évaluer les conséquences possibles de ce comportement sur la distribution et l'abondance de l'espèce à grande échelle.
