I caught the last of the surviving trout in late June. Many had markedly pink flesh, but not as pink as salmon. Interestingly, many still had pure white (ok grey or cream), indicating to me that some fish just didn't eat the pellets. No pictures to prove it this year.
Next Friday I get my annual shipment and these fish will be on the 5D19 pellets their entire time with me. I'll be sure to post a picture of their flesh color in the spring. I'm getting a mix of mostly rainbows with some brown, brook, and golden trout. One of my favorite events of the year - next Friday Oct 12th!
