Species and size selectivity in longline fishing: a review
The species and size selectivity of longlining is reviewed and discussed. Important selection factors in this fishery are fish distribution, fishing strategy, feeding range, fish competition, type and size of bait, and hook design. Larger species and specimens have larger feeding ranges and are more successful in competing for baits, which may explain the higher selectivity of longlining compared to trawling. The potential for further improvements in longline selectivity is discussed.
