Rapid growth gene helps trout adapt

Posted by Zach Goeden:

Researchers have recently found a very similar gene in populations of Rainbow trout in both Alaska and Idaho. This gene helps the trout to adapt more quickly and enables them to deal with a changing environment better than trout without this gene mutation. There is currently work being done on isolating this gene so that it may be used to help struggling populations of salmonids in other locations. If this gene can be used to help other populations recover then it will have enormous benefits for populations in other areas especially if the environment changes and speedy adaptation is necessary for survival. I have to wonder though, will it really help save the existing species/population or will it simply help the population to adapt and change into something different that can better survive in the habitat.
