okay, so to start tis out a few years back for biology i did a powerpoint on cutthroat trout in my local creek. i did a lot of research relating to eating habits,preffered water and spawning habits after reading into spawning habits it said that cutthroat trout are becoming more rare and hard to find in steady poulations, not only due to some invasive species but actually other trout, the rainbow trout is more dominate and succesful with spawning and they out spawn native cutthroat or they even cross breed with them and phase them out and pretty much take over and it does not take much time . as i soon found out there were rainbow trout in my home creek and lake i started to get a bit worried, over the past two years i have caught more and more rainbows and less cutthroat.. has anybody else experienced this happen like i have? and what are you thoughts on it and why do you think it happens? the only thing i could think of is some of the wild winter steelhead smolts (upper willamatte fish) stayed instead of going to sea and starting breeding in freshwater. thanks for your opinions and comments it would be nice to get an idea of how and why this is going on and how common it is.
