Seabird Species Caught in Bottom Trawls

These species have all been recorded as caught in bottom trawls (International Standard Classification of Fishing Gears codes 03.11-03.14, and 3.19, which includes otter and beam trawls).

There are 42 species of seabirds recorded caught in bottom trawls. The large majority of these, 29, are tubenoses (Procellariiformes), and 11 of these 29 are albatrosses. However, 12 of the overall 42 species, including eight of the albatrosses, are either non-diving or very shallow-diving species, suggesting that these birds are being caught only when the net is being hauled and close to the surface.

This suggests that an important way to reduce seabird bycatch in these trawls would require making changes when hauling the net.

If you are interested in more details about bycatch in any of these species, go to the map tool, choose "Explore by Species," select the species (probably easiest in the "Common name" drop-down box), submit the query, and get a comprehensive report for your species of interest. The report will list all of the references regarding bycatch in the "Gear Interaction References" section.
