The island Territory of Guam currently serves as a homeport for a large purse seine fleet and in the later part of 1986, the longline transshipment industry also became a significant component of the island's economy.
The vessels are offloaded next to the transshipment packing facilities. On board ship marlin catches are usually headed, gutted and tailed and stored in packed ice. Tuna catches are stored whole in packed ice
Landed fish are individually weighed, inspected and classified as "A", "B", "C", or "rejected" by an experienced grader. Quality of each fish is determined by cutting out part of the flesh next to the caudal peduncle and inspecting it for color and texture.
All graded fish are individually boxed and palletized for the air cargo to the Japanese fresh fish market.
