Salmon come down the "channel like tube" into a tank filled with carbon dioxide. This makes them sleepy and easier to work with. Each fish is scanned for a "coded wire" which is a magnetized stainless steel wire about 0.25 mm in diameter with numbers that indicate the hatchery and year spawned. The wires are cut by an injector that hypodermically implants them into suitable tissue on the fish, usually the snout. If the scanning indicates that the fish is "ok", it's snout is placed in the blue looking machine on the table which "zaps" it. Then another group of "fish guys" take measurements and cut off the head of every 4th fish for sampling. The fish are placed in large containers with salted ice. The tribal members leave the hatchery with hundreds of salmon.

Lids will be placed on containers and fish are ready to be transported.
