Purse Seining
Vessel: 150-250-foot vessels
Method: These vessels use mile-long nets to encircle the tuna. These
nets encircle the tuna and are closed off by drawstrings much like a drawstring purse. They are rapidly
cooled by placing them in holds filled with refrigerated seawater or chilled brine and are then frozen.
Fish: Used to catch skipjack and yellowfin tuna that make up the majority
of the light canned tuna pack.

Longlining
Vessel: 80-200-foot vessels
Method: Bait and hook method: six-60-mile mainlines and branch lines with
baited hooks catch two to three fish per 100 hooks.
Fish: Mature albacore that average 25-40 lbs.


Trolling
Vessel: Ships 25 to 90 feet in length in length
accomplish this method of fishing. Carrying capacity is generally 25-100 tons of frozen tuna.
Method: Eight to 12 lines with baited hooks tow the fish. The lines are
pulled by hand or by hydraulic haulers. The fish are quickly unhooked upon landing and are stored whole in
blast or spraybine freezer holds.
Fish: Albacore that are generally 10-20 lbs. and have a higher fat content.
