Here is Alan's reply:
"Once a Kokanee goes into spawning mode and turns red, it is dead. There is no going back. Kokanee in Strawberry do not always find a stream to spawn in, and over the years we have observed what appears to be spawning activity in the reservoir. Kokanee have been documented to successfully spawn in lakes and reservoirs elsewhere, and it is fairly apparent that they also attempt this in Strawberry Reservoir as well. We have not initiated any type of study to document the success of stream vs reservoir spawners to date. We looked into it a few years ago through microchemistry, but the chemical signatures among streams and the reservoir were too similar to distinguish among them. However, on average about 45% of our population of kokanee comes from natural reproduction. Some years better, and others worse obviously. I just can't tell you what proportion comes from reservoir spawning as opposed to stream spawning activity. Hope this helps
