Coastal nursery areas are subjected to a wide range of natural and anthropogenic stressors, including global warming, which indirectly influence trophic food webs. A global rarefaction of n-3 polyunsaturated fatty acids (PUFA) in trophic networks is in progress. The aim of this study was to assess the effect of a reduction in the dietary availabili...
Une des questions cruciales dans le débat écologique actuel est de déterminer si la plasticité phénotypique pourra permettre aux espèces de répondre au rythme rapide des changements environnementaux en cours. L’objectif général de cette thèse était d’étudier les effets d’un appauvrissement en acide gras polyinsaturés du type n-3 (AGLPI) sur la plas...
Global climate changes have led to a depletion in omega-3 polyunsaturated fatty acids (n-3 PUFA) in marine phytoplankton that—with food web transfers—could negatively impact fish performance. The aim of this study was to assess the effect of a reduction in the dietary availability of n-3 PUFA on growth performance, organ allometry, and fatty acid c...
The development of breeding programs for aquaculture and the preservation of biodiversity justify gamete cryobanking where samples of semen and embryos are preserved. Short-term storage is a complementary tool to cryopreservation, allowing gamete transport to the place of conservation. Here, we developed a short-term storage protocol for great scal...
The pace-of-life syndrome (POLS) hypothesis1 specifies that closely related species experiencing different ecological conditions should differ in a suite of metabolic traits that have coevolved with the life-history particularities . The notion of POLS finds its roots in the classic concept of r and K-selection. It also extends into the more recent...
A basic cryopreservation protocol for great scallop sperm was recently published, with which thawed sperm survival remained limited to 25% of control values (Suquet et al. 2014). We designed here a set of five experiments to test ways of improving thawed sperm survival and storage by studying the effects of (1) cryoprotectant concentration; (2) sug...
