The other marking trailer is a bit more straight forward. This is used for the marking of the 1.7 million Coho raised here at the hatchery.
The fish are sized and counted by the pound.
Moved to the inside holding tank,
the fish are hand dipped, anesthetized and their adipose fin is removed.
The fish are placed in the trough closest to the clipper and sent back to the raceway. Spending only a few days back in the raceways, they are transferred to the rearing ponds.
