The Undersecretariat for Fisheries and Aquaculture of the Government of Chile has proclaimed Resolution No. 2941 “Establish Management Measures to Reduce Incidental Catches of Seabirds in the Trawl Fisheries” of 28 August 2019 that makes adoption of defined seabird mitigation measures and good practices in trawling fisheries mandatory.
The resolution requires the adoption of management measures aimed at avoiding or minimizing the incidental catch of seabirds in various types of trawl fisheries carried out in waters under national jurisdiction or on the high seas by vessels flying the Chilean flag, through the mandatory use of equipment or devices and compliance with the best fishing practices set out in the resolution.
The required mitigation measures (in unofficial translation) include the deployment of twin bird-scaring lines (BSLs), at least 30 m long and with brightly coloured streamers (in certain fisheries and conditions bird bafflers may be used instead). In addition, nets must be cleaned before shooting. At night time the use or BSLs or Bird Bafflers may be dispensed with. A snatch block must be installed on the stern of the vessel to reduce the height of radiosonde cables when used. In certain defined trawl fisheries net binding is required to minimize the time the net is on the surface, by increasing it sink rate and diminishing the time of exposure when it can interact with seabirds. Discard management includes avoiding discarding during trawls and an overall reduction in the at-sea disposal of fish waste.

Valeria Carvajal, Managing Director, Federation of Fishing Industries of the Austral Seas writes: “In our view, this resolution provides explicit measures which are in the line with ACAP's best practices and we are hopeful it could help to reduce even more the incidental mortality of seabirds in our fishing operations. The scientific observer programme carried out by IFOP (Instituto de Fomento Pesquero) together with the monitoring system through on-board cameras on all industrial vessels, will provide a broad observation of all fishing activity, including incidental mortality of seabirds.”
The new resolution follows on from Chile adopting its National Action Plan to Reduce Incidental Catches of Seabirds in Longline Fisheries (PAN-AM/Chile).
