What is long lining used for?
Longlines can be used to capture fish in surface waters (pelagic) as well as bottom living species (demersal). Longlining sets a length of line and from this come branch lines carrying baited hooks. Large longlines used offshore can be tens of kilometres long and carry thousands of hooks.
Why is long line fishing bad?
An unfortunate consequence of the longline design is that it attracts and easily snags non-target marine life (known as bycatch). A wide range of animals such as sea turtles, sharks, seals, seabirds, and marine mammals can get caught on hooks or entangled in fishing line (Fig. 1).

How are fish caught on a drop line?
How dropline fishing works. Droplines use a main line with an anchor at one end and a float at the other.

Droplines are normally left to ‘soak’ for around 6 hours before being hauled.
