I was aware of some of the issues, same as with all non-wild #animal sources, of horrific living conditions and the negative #environmental impacts of concentrated animal waste (shit and piss) and #chemicals like #pesticides, connected with #fish #farming (#aquaculture), but I was completely ignorant of the threat to the existence of #wild #species if #interbreeding occurs.
I severely limit #seafood and #meat in my diet, and will try to avoid farmed fish especially.
