Hatcheries and fish farming are two totally different things.  You have no idea what you are talking about.  Literally........complete ignorance.    Hatcheries simply hatch fish from salmon eggs and release them to insure higher survivability. 

Farmed salmon are genetically modified frankenfish with strange immunities, and non immunities, possible strange mutations, and all manner of genetic morphology possible in future generations that could devastate their, and wild animals survivability, and ultimately our own. 

You are so wrong about your ideas on this topic that it is unbelievable you feel comfortable commenting.  Stop........you are misleading others !!!!!!
