Cetacean-fishery interactions in Galicia (NW Spain): results and management implications of a face-to-face interview survey of local fishers

Study Type
Field study in the wild
Location
Galicia Spain
Target catch
Various
Effect on bycatch species
Substantial economic loss can occur from interactions between bottlenose dolphins and gillnets. Cetacean bycatch mortality highest for set gillnets.
