Trawls are large nets towed either in the water column (mid-water trawls) or on the seafloor (bottom trawls) depending on the target catch. Anything caught is funneled into the codend at the end of the net which is hauled onto the boat and dumped on the deck.
Hotspots are areas that have a higher abundance of bycatch taxa where it is more likely to have high bycatch rates if fishing is conducted. It is a best practice to avoid setting fishing gear in these locations.

Turtle excluder devices are modifications to trawl nets that block specific taxa from getting dragged into the cod end of the net and allows them to swim out while the trawl net is being towed.

Marine mammals and sea turtles can be caught in the net and drown if not able to surface to breathe. Other than excluder devices, there are few mitigation options and the most effective bycatch reduction is modifications to fishing methods.
