Aquaculture environmental impacts affect wild animal welfare through habitat destruction, pollution, and disease. Sustainable aquaculture practices protect both farmed and wild animal welfare.
Aquaculture environmental welfare impacts create welfare harm at two levels simultaneously - wild animals affected by habitat destruction and pollution, and farmed fish whose welfare is often compromised in the intensive systems that cause most environmental harm. Sustainable aquaculture that minimizes environmental impact often also represents better welfare for farmed animals.
