Species Caught in Midwater & Pelagic Trawls

These species have all been recorded as caught in midwater and pelagic trawls including those described as "middle depth" (International Standard Classification of Fishing Gears codes 03.21, 03.29-03.9).

There are 30 species of seabirds recorded caught in pelagic and midwater trawls. Almost all of these, 28 of the 30 species, are tubenoses (Procellariiformes), and eight of these 28 are albatrosses. Eight of the overall 30 species, including four 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. Many of the remaining species may also possibly be caught when the net is near 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.
