Four years ago, 5.2 million juvenile fish (4.6M Chinook, 600K Steelhead) were released into the Willamette Basin Rivers (Coast Fork, Middle Fork and Main stem Willamette, McKenzie, South and North Santiam, Mollala and others). With each fish costing roughly $1 each to raise, this was a sizable investment for the ODFW, NOAA and other government entities. And this is not a one-time thing, it happens every year. Why you may ask? Simple – to replace wild fish runs lost due to the construction of dams.
We replace the lost fish (due to being cutoff from spawning habitat) with hatchery raised fish of similar species so that commercial and sport anglers can continue the business/sport of catching fish.
So, how’d it all work out?
For Spring Chinook, it went pretty well, we have roughly 50,000 Spring Chinook making their way back to the hatcheries they were released from. That’s a return on the investment of 1.1%. It’s the best return of Spring Chinook we’ve seen in the last five years. That’s the good news.
