On June 15, 2017 we performed our fourth fin clipping exercise at Hoy Creek Hatchery for our coho salmon fry.

The adipose fin is removed after the fish are sedated. It's a fast process and many careful hands make light work.

The entire procedure is overseen by the Department of Fisheries and Oceans. All fry recovered expect one of approximately 5500 fishmarked.  The markings help the society identify hatchery fish during returns in the fall.

Thanks to Hoy-Scott Watershed members who provided the photos seen here.

On June 21st, 2016 the Hoy-Scott Watershed Society conducted another successful fin-clipping exercise with over 6000 young coho salmon which had been thriving in the Capilano trough room of the hatchery located on Hoy Creek since approximately December 2015.

"This was our third year of doing the fin clip exercise to identify our fish as 'hatchery' salmon," said hatchery manager, Rodney Lee. The fish are first sedated, and then the adipose-fin (small top back fin) is carefully snipped off. The entire operation is overseen by the Department of Fisheries.

"We clipped over 6000 fry in two hours thanks to our volunteers," said Rodney. "The fish recover quickly and will be moved to our rearing pond in a few days, where they will live until their release next May. They will then head out to the ocean, and when they return, this is our way of identifying them."
