Sine I heard the same arguments when hatcheries were being started around Alaska.  Yet today hatcheries contribute lot of fish to the commercial fisheries catch.  Ask our Alaskan fisherman if they want to stop the hatchery operations and you will get an abundance of NO replies.  It all gets back to the market value of Alaskan branded wild salmon over all other salmon. The truth is you can not tell a wild salmon from a hatchery reared one once they are canned.
