CCAMLR streamer line requirements revisited

The streamer line has become the primary seabird mitigation device prescribed and used in most longline fisheries throughout the world, based to a large degree on the precedent set by CCAMLR in 1991. This discussion paper responds to the interest of the IMAF working group to consider possible revisions to the CCAMLR streamer line requirement. Existing literature on the effectiveness of single and paired (or multiple) streamer lines is reviewed and CCAMLR streamer line performance and material standards are discussed and contrasted with recent Alaskan requirements.
