I realize fish eggs are a valuable source of protein in any river system, and that there are going to be predators any time there in abundance. I have a few questions regarding steelhead spawning habits. How exactly do the steelhead manage to keep their eggs in their redds, is it just because they've dug a depression below the main river current or do they cover the eggs with clean gravel? Do the dollys arrive in any particular river before the steelhead or follow them in the hopes of picking off a free lunch? One more question: do the dollys spawn in the main river later than the steelhead or move up into the smaller feeder creeks after loading up? I assume after spawning some dollys or bull trout remain in the river to feed on the fry............c/22
