Idaho kokanee - interactive story

[MMDon]

Basically Kokanee are Kokanee. The Maturation Timeline really depends on an abundancy of food in the biomass. With the huge amount of nutrients and minerals that wash into Flaming Gorge via the Green River, the Kokanee feel no threat of a food shortage and many but not all simply put off going into spawning mode at 3 years. We see the same pattern in years of abundance of food in the Pacific Ocean and King Salmon not returning to spawn until the 4th year.

I should have noted that we do see some 4 year Kokanee that naturally spawn in Palies as well.
