Here is the answer I received from the PM I sent:
[quote IDFG_Fisheries]Greetings Curt,
Ririe Reservoir surveys are managed by Brett High in the Idaho Falls office. I'll get in touch with him and see if he can give me a summary of what they found.
If you guys are seeing 16" kokanee, it probably means that there are going to be fewer of them around. Kokanee all eat the same thing - plankton - so when there are a lot of kokanee, they compete for the same food. Few kokanee means less competition and much higher growth.
I'll see if Brett's crew has had time to look at the survey data yet. This is a very busy time of year with all the various surveys, so they may not yet have gotten to crunching the numbers quite yet.
I'll keep you posted.
