Objective	Estimation of the size composition of discards for hake, Nephrops prawns and sole by small-scale offshore trawlers fishing between the Glénan islands and the Landes coast. The samples taken supplement the sampling done in some fish auctions and make it possible to obtain the size composition of catches (landings + discards) of fishing vessels. This cruise is part of a quarterly observation programme.
