In the context of Pacific oyster C. gigas summer mortality, the present study demonstrated that the reproductive effort reduced not only the energetic parameters (carbohydrates and CEA) but also the immune parameters (concentration, phagocytosis and adhesive capacity of hemocytes). Increasing food supply from 4% to 12% (of oyster dry weight) did not counteract this phenomena as most of the additional energy was dedicated to the gametogenesis processes. However, after the gametogenesis, the 12% diet clearly favored energy storage restoration and hemocyte production. Hemocyte parameters were also modulated by the food quality. Indeed, hemocyte concentration tended to increase 20:5n-3 and/or 20:4n-6 were supplied by micro-algae or artificial diets. When these...
