CAMP Connectivité des Aires Marines Protégées. Mars 2009-Octobre 2012. Rapport Final ArchiMer
Bourjea, Jerome; Evano, Hugues; Muths, Delphine.
The main objective of the CAMP project (2009-2011) was to estimate the effective connectivity between Marine Protected Areas (MPA) in the southwest Indian Ocean (SWIO) through population genetics of 3 biological models Epinephelus merra, Lutjanus kasmira and Myripristis berndti. The ultimate goal is to provide scientific results for managers to contribute significantly to the design of the MPA network in SWIO. At the end of the project and thank to the cooperation with the Natural Marine Reserve of La Réunion and 5 international partners from the SWIO, 414 M. berndti, 623 L. kasmira and 731 E. merra were sampled in 16 different sites (Reunion, Mayotte, Geyser, Europa, Juan de Nova, Glorioso, Rodrigues, Mauritius, Moheli, Grande Comore, Seychelles, Kenya,...

CAMP – Connectivité des Aires Marines Protégées - Période Mars 2009 – Février 2010. Rapport intermédiaire ArchiMer
Muths, Delphine; Bourjea, Jerome.
The main aim of the CAMP project (2009-2011) is to estimate the efficient connectivity between the Marine Protected Areas (MPA) of the South-West Indian Ocean (SWIO). For that purpose, we use a population genetics approach on 3 reef fishes: Epinephelus merra, Lutjanus kasmira et Myripristis berndti. The overall goal of the project is to provide new elements to MPA managers that will contribute to design the best network of MPAs in the SWIO. In the first year of the project, most of the time was spent to sample fishes. Based on collaborations with 5 international and national partners, we succeed to sample more than 1100 fishes within 12 sites of the SWIO. More than 850 of the 1100 fishes were already sequenced. The development of third microsatellite...

Écologie de la reproduction de l’huître Crassostrea gigas en lagune méditerranéenne ArchiMer
Lagarde, Franck.
The Mediterranean lagoons host many anthropogenic uses including shellfish aquaculture since the beginning of the 20th century. Imported in 1970, the cupped oyster, Crassostrea gigas, has adapted perfectly and has allowed an important development of oyster’s industry until 2008, the year of occurence of spat outbreak related to the emergence of an Ostreid Herpes-virus μvar. The scarcity of spat and the speculation on this product changed regionally cultural practices and the supply of juveniles, with in particular the wish of developing a local activity of spat collection. However the cycle of reproduction of the species and the recruitment of juveniles were poorly known in lagoon environments. In this context, the objective of this thesis is to...

HLiN. Huı̂tres du Littoral Normand. Ponte, Dispersion, Recrutement et Colonisation des huı̂tres sauvages sur l’Ouest Cotentin : un réseau de suivi pour le littoral normand. Etude de cas 2013 ArchiMer
Pien, Sebastien; Maheux, Frank; Dedieu, Karine; Le Gendre, Romain; Simon, Benjamin; Gauquelin, Thibaut.
Depuis 2010, le programme HLiN s’attache à suivre la colonisation et le recrutement des huîtres naturelles sur les côtes du département de la Manche. Après une période d’adaptation des protocoles à la réalité normande, il s’est posé la question de l’origine du recrutement des huîtres, notamment pour la côte ouest du Cotentin, entre les falaises de Champeaux et Saint Germain / Ay. Suite à ses travaux sur la dérive larvaire des moules de pêche en baie de Seine, le LERN de Port en Bessin avait mis au point un modèle de courantologie en 3 dimensions appelé NORM (issu du code MARS 3D). L’idée était d’appliquer la méthodologie de calage du modèle pour le golfe normand breton afin de simuler différents scénarios de ponte et de les corréler avec les observations...

Modélisation de la distribution d’espèces benthiques par l’utilisation d’une plateforme multi-agents ArchiMer
Razafimahefa, Ntsoa Rakoto.
In a context of climate change, understanding the response of species to changes in the environment and the implications for their geographic distribution is paramount. Species distribution models (SDM), through the formulation of relationships between the organism and its environment, provide a tool to explore species response to different types of environmental stresses. This study presents the development and a first application of a mechanistic and generic SDM, using a multi-agent modelling platform: NetLogo. The model allows to simulate the spatialized population dynamic of a bentho-pelagic species, in response to environmental variations. The model developed is an individual-based (IBM) mechanistic model, which incorporates a DEB (Dynamic Energy...

Projet GERMON. Structure génétique et migration du thon Germon ArchiMer
Nikolic, Natacha; Puech, Alexis; Chouvelon, Tiphaine; Munschy, Catherine; Bodin, Nathalie; Brach-papa, Christophe; Potier, Michel; West, Wendy; Knoery, Joel; Zudaire, Iker; Dhurmeea, Zahirah; Degroote, Maxime; Cedras, Maria; Evano, Hugues; Bourjea, Jerome.
The GERMON project had several aims i) to understand the populations’ structure between albacore tuna southwest of the Indian Ocean and southeast Atlantic, ii) to determine the origin of juveniles observed in South Africa iii) to improve the understanding of the biology field (Size/Size and Size/Weight; reproduction and feeding area; trophic linkages) and iv) to initiate work on chemical analyzes and adaptation of the albacore species to its environment. These aims have been held and the results allow a better understanding of the management albacore. A general summary of results is presented in Part 9.
