Results on Northern hake Spanish discard sampling programme
Quarterly discards estimates for the Spanish bottom otter trawl fleet fishing in the Northeast Atlantic ICES Subareas VI and VII are presented for hake (Merluccius merluccius). Information was obtained by observers on board under different discard sampling programmes carried out by the Spanish resea...
