The fishery for benthic species (Monkfish, Megrim, Rays, etc ... ) represents for the surrounder countries of the Celtic Sea and the Bay of Biscaye one of the most important activities . An estimate of the discards of the main species resulting from the sorting practice onboard of the trawlers participating in this fishery was made in 1985 and 1991. it was concluded that an important quantity of juveniles of Rays, Megrim and Monkfish are discarded each year causing an important mortality. The aim of the present paper is to present the preliminary results of a selectivity grid fixed on a bottom trawl to limit as possible the discards. Three different grids were tested at sea during surveys with different results. The major problem is due to difference in the behaviour of the main species in front of the grid. Finally a good compromise was realised with a grid made of vertical bars and horizontal ones respectively of 110 mm and 50 to 60 mm spacing.
