A group of organizations has written a letter to the Food and Agriculture Organization (FAO) expressing concerns about the sustainability of the global aquaculture industry, with a focus on the rearing of carnivorous fish like salmon, sea bream, and sea bass. The letter highlights the negative impacts of these farms, including the depletion of wild fish stocks, damage to marine ecosystems, pollution, antibiotic and chemical use, and the inefficiency of feeding carnivorous fish with wild fish. The FAO's goal to increase global sustainable aquaculture by 75 percent by 2040 is called into question, as the majority of funding is allegedly being allocated to destructive open-net marine carnivorous fish farms in Europe. The signatories are pushing for the FAO to distinguish sustainable aquaculture practices, such as seaweed and bivalve shellfish farming, from the destructive practices of carnivorous fish farming.
