Seabird Species Caught in Trolls and Jigs

These species have all been recorded as caught in trolls and jigs (International Standard Classification of Fishing Gears codes 09.4 and 09.5).

There are 21 species of seabirds recorded caught in trolls and jigs. All of the species caught on these gear are divers except Short-tailed Albatross, Brown Noddy, and Audouin's Gull. Half of them are plunge divers, such as gannets or boobies, that will dive on their prey (in this case, mistaking the bait or jig for their prey) directly from the air into the water. Three of the remaining nine species are surface divers. Therefore, 14 of the 21 species are either plunge divers or surface divers, suggesting that the birds are caught when the bait or jig is near the surface of the water.

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.
