Bycatch Mitigation Fact-sheet 7b. Pelagic Longline: Streamer lines (vessels <35m). English, French, Japanese, Korean, Portuguese, Simplified & Traditional Chinese, Spanish.
Streamer lines are the most commonly prescribed seabird bycatch mitigation measures for longline fisheries. However, recent evidence shows that they are not fully effective unless combined with other mitigation measures. To reduce bycatch to negligible levels they must be used in combination with branch line weighting and night-setting.
