A good person to contact if you've got scales that you'd like read would be Kate Meyers with the UW high seas salmon program. They read tons of scales every year, so they're pros, plus Kate is an avid steelheader so she might take a particular interest. I'm sure there are folks at the state/NOAA doing this stuff too, but I'm not familiar with any of them. Chad, you're probably right. Steelhead and salmon loose their scales relatively easy when they first enter freshwater so sampling is really pretty simple. When they've been in the river a while though their scales tend to tighten up. Anyway I was just saying its a relatively easy way to find out if you're really curious.
