Common amongst the more than 150 studies that concluded hatcheries had an adverse effect on wild salmonid populations were negative impacts such as reduced genetic diversity due to interbreeding with hatchery fish, reduced average size of wild fish, reduced overall abundance of wild fish populations, and reduced fitness for natural reproduction.
Fish and seafood. There is no sustainable fishery and the oceans are dying because of it.
I’m surprised this is the first I’ve heard of this, are local fish hatcheries not sustainable?
They are not
