Seabird Species Caught in Handlines and Harpoons

These species have all been recorded as caught in handlines and harpoons (International Standard Classification of Fishing Gears codes 09.1, 09.2, 09.9, and 10.1). These include pole and line gear, and may include pole and line used by recreational and sport fishers. All records of seabird bycatch are on hooks; none on harpoons.

There are 58 species of seabirds recorded as having been caught on handlines. Of these, the largest group is the gulls and terns, with 22 species, more than one-third of the total. The cormorants, shags, and boobies are represented by 13 more species. Fourteen species are either not diving species or surface divers, that is, species that do not dive beyond about 1 m depth. These include several albatrosses and most of the gulls and terns. In general, the species recorded as being caught on handlines are not the more adept, deep-diving species. This suggests that most of the birds being caught on handlines are being caught when the hook is fairly near the surface. Exceptions to this general rule may be the two alcids (Common Murre and Marbled Murrelet) and the more deep-diving shearwater species. 

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.
