  1. Set lines underwater to reduce seabird bycatch

    A review of two randomised, replicated and controlled studies off the coast of Norway (Løkkeborg 2003) found that fewer northern fulmars Fulmarus glacialis were caught on longline hooks when an underwater setting funnel was used (34 birds and 0.08-0.49 birds/1,000 hooks) compared to control line sets (174 birds and 1.06-1.75 birds/1,000 hooks). Both papers are outlined above.

     

  2. Use streamer lines to reduce seabird bycatch on longlines

    A literature review of three replicated and controlled studies off the coast of Norway (Løkkeborg 2003), found that only two northern fulmars Fulmarus glacialis were caught on 185,000 longline hooks when a streamer line was deployed, compared with 205 birds (mostly fulmars) from a similar number of hooks without streamer lines. The three studies (6, 11, 14) are outlined in detail above.
