What type of fishing vessel is it?
Longliners catch bottom fish like halibut on a long hook-laden line that is laid on the sea floor. Longliners are usually 45-80 feet in length and of two types - fixed or snap-on gear. Numerous orange buoys and flags are tied along the rails when in port.

What does it catch?
Longliners mostly catch halibut, cod, and rockfish. Halibut, the main catch, are huge flatfish that live on gravel or sandy bottoms in water from several feet to 200 fathoms (1200 feet) deep.

Where does the catch end up?
Fish are packed in ice in the vessel's hold for sale to fresh and frozen markets. Larger longliners can pack 20-40 tons of fish before returning to port.
