John--I'm quite confident it was a hatchery-raised fish (again, compare the coloration and placement of red spots) but it probably had been in Straight Fork a good while. The jaw is suggestive in that regard and the taste even more so. In the latter regard, I would note that hatchery-raised fish of today taste much better than was once the case. I suppose changed food is the explanation.
As for eating the catch, you've got me a bit envious and considerably peckish just thinking about a mess of fried trout. I'll rectify that in a couple of weeks.
