No one knows what organism populations these fish will devastate, ........and if even one mutates with functional sperm or eggs, it will create havoc.     

Remember when Monsanto pollen travelled to other farmers fields and ruined their seed stocks, and this modified their seed DNA to "round up ready" DNA structure ????????     Then Monsanto turned around and sued the farmers for using their own seeds, that Monsanto seedstock had polluted with Monsanto's filthy seed. (literally).  This is archenemy stuff folks, and the superwealthy and greedy filth, like the Trump's, are trying to take control of everything and everyone.  Don't be naïve.
