Deep Species Results from Spanish Discard Sampling Programme
Estimations of deep species discards from three Spanish bottom otter trawl métiers 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 was the...
