this is from the TP website for Cushman Fish Project report for 2020;

"Our release goal for sockeye is 2,000,000 each year, but obtaining the eggs has been a challenge.

“Puget Sound Energy’s Baker Lake stock provides us with the eggs, but, due to scarcity issues, they have only been able to provide 250,000 to 500,000 eggs per year, and this year they won’t be able to provide any,” Andrew said. “They are our only option – no other basin that has a large-enough run that could spare any. Thankfully, we had 127 fish return, about half of which are female, so we should have roughly 100,000 eggs.”

Let's just say you have plenty of time to get your sockeye gear ready.
