Best practice seabird by-catch mitigation for Spanish-rig longline vessels with emphasis on line weighting regimes
Abstract: The Spanish system is used in a range of demersal and semi-pelagic longline fisheries ... throughout the southern hemisphere and has been the source of a large number of seabird fatalities. An ... experiment was conducted on a chartered Spanish-rig vessel to improve the sink rate of longlines to reduce ... interactions with seabirds. The benchmark sink rate was that of integrated weight (IW) longlines, as used by ...
