When you look at all that water it doesn't seem like much, but it's like comparing the weight of the leaves on an oak tree to the weight of the entire tree. It doesn't seem like much but without the leaves, the tree dies. McRobb admits, however, it would take a lot to kill the lake. That's not his concern right now. The whitefish and their survival is what he's focused on.
Whitefish is a major part of the trout diet and it's the same with the pike.
They probably even eat each other. It's an important prey species in the whole ecosystem. John Ostashek was a fishing guide, this would be a little bit different. Aishihik is one of the few remaining lakes in the area where trophy fish can still be caught, he adds. The big fish are gone from Marsh and Tagish Lakes.
