Species Caught in Pair Trawls
These species have been recorded as caught in midwater/pelagic and bottom pair trawls (International Standard Classification of Fishing Gears codes 03.15 and 03.22).
There are only three species of seabirds recorded caught in the pair trawls. All three are diving species, although the Gray-backed Storm Petrel is only a shallow diver, and the other two species are not known to dive to great depths (mostly less than 40 m). This suggests that these birds are being caught only when the net is near to the surface, as when being hauled.
Although few species have been recorded caught in pair trawls, it is likely that many species caught in single trawls may also be suspceptible to being bycaught in pair trawls. Therefore, it is best to also consider the species recorded caught in the midwater/pelagic trawls and bottom trawls.
This suggests that an important way to reduce seabird bycatch in these trawls would require making changes when hauling the net or when the net is otherwise near the surface.
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.
