As early as 2004, scientists found levels of polychlorinated biphenyls, a probable carcinogen known as PCBs, seven times higher in farmed Atlantic salmon than in wild salmon. In addition: Untreated waste from excess feed, decomposing fish, excrement, and chemical residue forms a toxic stew that kills or drives away marine life for hundreds of yards. The management of farmed fish includes antibiotics, probiotics, injectable vaccines, breeding maintenance, nano-based drugs, and edible vaccines, all with monitoring requirements. Of course, disease resistant mutant strains result from antibiotic treatments. Hence, the vaccine program. When it comes to drug use in global aquatic products: Long-term use of chemical inputs not only increases pathogenic bacteria resistance but also damages the fish and aquaculture environments, resulting in drug residues in aquatic products. https://activistpost.com/2024/11/the-farmed-fishing-disaster.html
