Performance-Enhanced Rainbows, On Their Way to a Stream Near You

If Mark McGwire had eaten only creatine-laced rainbows, would he still have set the single-season home-run record in 1998? If one were seeking a world-record trout, would the extra muscle mass of juiced fish be offset by the five-old stamina increase promised by chemical enhancement?
Ok, those are the silly questions, but there are some interesting — some would say disturbing — possibilities raised by the research of fisheries expert Rob Hayward, including the potential to increase aquaculture productivity.
“If Creatine-laced rainbows are in fact a better fighting fish and eventually become mainstream, some worry that our environmental standards will erode. After all, fish managers can just release more Creatine-enhanced trout into our streams and rivers without having to worry about water quality, they say.” Babe Winkleman on

    I love the idea of catching a true wild trout. I do not think this is a good idea. What will the next generation be like? Will it change there color? What will happen to the native trout? Are they going to feed the bugs creatine so the fish can continue to get there creatine after they have been released? Will they be super aggressive and kill the other fish? I SAY HELL NO DO NOT PUT THEM IN OUR WATER!!!!

    I agree, this does “sound” appealing, but as most things do, it could be a huge detriment to local fisheries. As stated above, these fish could become hyper-aggressive and kill the other stock and native fish? They could wipe out the smolts before they have a chance to grow.
