  10. 10. Longlines: baited hooks on lines varying in length from 15 to 100 kilometers set with floating buoys or sunk with weights depending on the targeted species. Sea lions, fur seals, toothed whales, and other marine mammals can get caught on the hooks or tangled in the lines.
  11. 11. Gillnets: mesh nets that can be set on the sea floor or floated in the water column depending on the targeted species. Marine mammals that dive for food around gillnets tend to become entangled and drown when they are unable to surface for air.
  12. 12. Trawls: funnel-shaped nets that are dragged behind boats at different depths, depending on target species. Marine mammals are attracted to trawls, which they become entangled in, because they often target the species that mammals prey upon.
  13. 13. Purse seines: nets that hang vertically in the water column using weights at the bottom and buoys at the top. They can enclose marine mammals in the nets, along with fish.
  14. 14. Bottom-set traps: (commonly called “pots”) crustacean traps with ropes that connect them to surface buoys and to one another. Large whales are particularly prone to getting entangled in the ropes, which wrap around their bodies, making it difficult for them to move or feed.
