Joe Peters posted a couple of updates on the Squaxin Island Tribe’s natural resources blog yesterday on two yearly spring activities, smolt trap and net pens.
First, smolt trapping:
Outmigrating coho salmon smolts will be captured, enumerated and lengths measured. Other species such as chum fry, cutthroat, rainbow trout, and sculpin are also seen in the trap.
And, net pens:
Each month Squaxin NR staff takes samples of coho from the net pens to monitor growth progress and fish pathology. We select pens that are representative of the stocks we have and then seine a random sample of these pens.
