Hey Jim, I release a lot of trout too. I'm a fly/spinner guy too, and release all wild trout/high mountain lake trout/small stockers. But where I mostly fish for trout in the springtime, the average size fish is 16-17" and between 1 and 2 pounds. A couple of those "stockers" will make a darn fine meal. These fish are triploids, by the way. Concentrate their energy on growth, rather than reproduction. I'm sure you know what they are. Anyway...anybody tried this stuff yet? Thanks again.
