Deep Species Results from Spanish Discard Sampling Programme
Estimations of deep species discards from three Spanish bottom otter trawl m etiers operating in the Northeast Atlantic ICES V I, V II, V IIIc and North IXa are presented in this paper. Information has been ob- tained from the `Spanish Discard Sampling Programme' carried out by the IEO. Trip wa...
