HIV-1 integrase catalyzes the insertion of the viral genome into chromosomal DNA. We characterized the structural determinants of the 3'-processing reaction specificity-the first reaction of the integration process-at the DNA-binding level. We found that the integrase N-terminal domain, containing a pseudo zinc-finger motif, plays a key role, at least indirectly, in the formation of specific integrase-DNA contacts. This motif mediates a cooperative DNA binding of integrase that occurs only with [...]

Fatty acid-binding proteins (FABPs) are small cytosolic proteins, largely distributed in invertebrates and vertebrates, which accomplish uptake and intracellular transport of hydrophobic ligands such as fatty acids. Although long chain fatty acids play multiple crucial roles in cellular functions (structural, energy metabolism, regulation of gene expression), the precise functions of FABPs, especially those of invertebrate species, remain elusive. Here, we have identified and characterized a [...]

L’objectif général de la thèse est de modéliser les principaux processus biologiques et économiques régissant des pêcheries multi-espèces et multi-flottilles afin de proposer des stratégies viables pour la gestion durable de ces pêcheries mixtes, dans un contexte stochastique et multiobjectif. Plus spécifiquement, cette thèse utilise des analyses de co-viabilité stochastique pour étudier les arbitrages entre des objectifs contradictoires de gestion (conservation, et viabilité économique et [...]

Estuarine sediment transport models require that a time variation of erodibility due to consolidation be taken into account. If numerical modelling of mud sedimentation and consolidation is currently satisfactory, simulation of mud-sand mixture consolidation is more problematical. This is partly due to mixed-sediment processes, as hindered settling and segregation, not well understood yet. Hence, based on extensive settling columns experiments, the aim of this study is to improve our [...]

The aim of fish breeding is to increase profit by producing faster growing fish with lower feed intake. However, little is known about the economic and environmental impacts of selective breeding programs for fish. We modelled a fish farm producing African catfish in a Recirculating Aquaculture System (RAS) to calculate economic values of growth rate and feed efficiency with production limited by fish density in rearing tanks and fish nitrogen emission. We also calculated “environmental values” [...]

The present study aimed to develop nondestructive methods to accurately follow the growth of fish larvae and post-larvae. European sea bass (Dicentrarchus labrax) aged 71-100 days post fertilization (dpf; 20-419 mg) and Nile tilapia (Oreochromis niloticus) aged 14 dpf (10-25 mg) were used as model species. Several measurements were performed on digital pictures of larvae to model body weight. Using body surface area, contour, length and depth, it was possible to estimate accurately the body [...]

The Working Group on the Application of Genetics in Fisheries and Mariculture (WGAGFM) convened in Olhãu, Portugal 7–9 May 2014. Members met to discuss and consider the five Terms of Reference (ToR) decided by the ICES Science Committee. The report contains the main issues discussed and the management recommendations for each of these ToRs. Dorte Bekkevold (Denmark) chaired the meeting, which opened at 09:00 on the 7 May and closed at 13.30 on 9 May. The meeting had 23 participants representing [...]

L’élevage des crevettes pénéides a connu un développement spectaculaire à l’échelle mondiale depuis les années soixante-dix, en particulier grâce à la maîtrise de l’ensemble du cycle biologique en captivité de plusieurs espèces d’intérêt aquacole (Aquacop, 1979). Elle a en effet permis de s’affranchir de l’approvisionnement aléatoire en juvéniles de pêche et en géniteurs sauvages, et par voie de conséquence de domestiquer ces espèces, c'est-à-dire de les sélectionner spontanément pour de [...]

La filière crevette de Nouvelle-Calédonie reposesur la maîtrise de la reproduction contrôlée de la crevette Litopenaeus stylirostris, espèce introduite dans les années 1980. La difficulté majeure que rencontre la filière depuis une dizaine d’années est la récurrence du « Syndrome 93 », qui s’exprime sous forme d’épisodes de mortalités lors des baisses de température aux intersaisons. Ces mortalités sont associées à la bactérie pathogène Vibrio penaeicida Une expérience de sélection sur un [...]
