Seasonal variations of physiological parameters in the blue mussel mytilus spp. from farm sites of eastern Quebec

摘要: A seasonal monitoring of indigenous (Gaspe Bay, Carleton, Havre-St-Pierre, Magdalen Islands and Blanc-Sablon) transplanted Havre-St-Pierre) mussels from different farm sites Eastern Quebec allowed us to study mussel physiology as a function environmental factors. positive influence phytoplankton cell concentration temperature on the reproductive cycle was discovered even if no significant relationship has been showed because fragmented pattern gametogenesis. decrease digestive gland index (DGI) observed during Development gametes needs much energy its great weight prevented correlate growth with phagocytic activity in each site midsummer, concomitantly most active spawning period. correlation remarked between maturity males phagocytosis. could then have direct impact population since it occurred high period when had face spawning, bacterial developments diseases. It appeared our that is key event important for farmers follow-up. In near future, we intend develop validate reliable indicators cultured mussels.
