Species Caught in Pelagic Longlines

These species have all been recorded as caught in pelagic longlines, also called “surface longlines” (International Standard Classification of Fishing Gears codes 09.31, 09.32, and 09.39).

There are 78 species of seabirds recorded caught in pelagic longlines. Except for the penguins and a few of the shearwaters, none of these species are deep divers. Ten species are not divers (see below) and one of these (Great Frigatebird) never even lands on the water. Of the remaining species, 15 are surface divers, very rarely going further than 1 m below the surface. This suggests that the birds on this list are being caught when the pelagic longline is very near the surface, either when being set or being hauled. There are very effective methods to reduce seabird bycatch when a longline is being set or hauled, primarily the use of bird-scaring lines (tori or streamer lines) or weighting systems.

Almost two-thirds (49 of 78) of species recorded caught on pelagic longlines are tubenoses (Procellariiformes; the albatrosses, petrels, fulmars, shearwaters, and storm petrels). Almost all species of albatrosses (20 of 21 species) have been recorded caught on pelagic longlines. Twelve species are gulls, skuas, or jaegers (Laridae and Stercoraridae in the Charadriiformes). None of these are diving species, but are rather scavengers. This is further evidence that the birds are being caught when trying to take bait when the line is beign set or trying to take items on hooks when the line is being hauled.

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.
