Objective	Inventory and distribution patterns in the water column at the end of the winter period of species from the Pseudo-nitszchia genus in the Iroise Sea and in Southern Brittany, in relation to hydrological structures. Studying the paths of domoic acid transfer in the marine food chain. The related project is ALTOX in Ifremer's programme 9 (Ocean and health).
