Disease/parasites: Viruses and parasites can transfer between farmed and wild fish, as well as among farms. [ 90 ] [ 91 ] Escapes : Escaped farmed salmon can compete with wild fish and interbreed with local wild stocks of the same population, altering the overall pool of genetic diversity.
The parasite can cause canine schistosomiasis, an illness that affects the liver and intestines of dogs, according to Dillman. Read more: It hit 120 degrees in this California town. For the ...
