Any history buffs among you bios out there??? So… I have been informed that Rainbow Trout are an introduced species here in the west. And… I have been told that the Steelhead is an anadromous Rainbow Trout. If that is so, was there Steelhead here before Rainbow Trout were introduced by man and how did the Native Americans catch Steelhead before Europeans arrived if the Rainbow hadn’t yet been introduced? Or am I way off base on this.
