I cannot recall the last steelhead I caught that was so deeply hooked that it bled at all. Are the bleeders in question being caught by drifting or plunking bait -- or by use of lures and flies? I imagine that there is more chance for a steelhead to swallow an egg cluster or nightcrawler than a lure or fly.
Even during the long number of years when I used bait for steelhead I don't recall many -- if any -- bleeders.
