Advantages -Bottom longlining has a much lower impact on the seabed then other methods Disadvantage -Longlining has a hard time attracting a specific species, thus there is a large amount of bycatch.  As well as cause danger to endangered sea turtles and sharks. -The process of deploying long lines can result in the death of seabirds that dive to try to steal the bait.  They are caught by the lines and drown.
