Demersal longline

Demersal longlines are set horizontally on the ocean floor. They can be many kilometres long and carry thousands of hooks. Baited hooks are attached to the longline by short lines called snoods that hang off the mainline. Demersal longlines are anchored to the sea floor.

Auto longlining is another type of longlining - it is basically demersal longlining except that some of the functions (for example baiting the hook) are automated.
