The thing about lake trout and Fish Lake is that lake trout very rarely use yellow perch as a forage. A big reason the DWR returned to kokanee in Fish Lake was to try and reduce the cost of feeding lake trout with rainbow trout and use a more self-sustaining population of kokanee as forage.
We have been saying for years that big fish are a result of fast growth and not old age...the interesting thing about Fish Lake is that you can have a 20-year old lake trout that is 25 inches or or a 20-year old lake trout that is 35 inches. Diet becomes the difference.
I would suggest anyone interested in fisheries management and especially fish growth read this (Pages 3-5 are the key pages in relation to this thread, but the whole thing is very informative):
