A new study showing that just one generation within a hatchery changes the heritable genetic make-up of steelhead at over 700 genes, with responses in a breadth of things such as wound healing, immunity, and metabolism!

Thanks for posting Michael Blouin's stuff.  The Hood River has provided a unique laboratory for studying wild steelhead.  All of the published work from there is supporting the need to change the way conventional hatcheries are operated.

Operated? Change the way they are designed! Scrap everything and start over. Build them like the Weaver Creek Spawning Channel in B.C. http://www.pac.dfo-mpo.gc.ca/sep-pmvs/projects-projets/weaver/weaver-eng.html
