Knowledge, Attitudes, Perception and Willingness-To-Pay for Animal Welfare and Environmentally Friendly Certified Salmon Products in Chile: The Case of Bio Bio District.

Aquaculture is expanding rapidly to meet growing protein demands, now providing over 50% of aquatic animal food. Salmon farming is especially important in Chile due to its favorable conditions and cost advantages. However, the industry faces challenges, including environmental sustainability and public perception. This study surveyed 396 people aged 18-65 in Chile's Bio Bio region about their knowledge and views on salmon farming and animal welfare. Results showed limited public understanding: 76% were unaware of information sources, and 52% were unsure of the industry's national role. Many viewed the industry as nontransparent, environmentally harmful, and poorly regulated, though its economic impact led to general acceptance. Knowledge of animal welfare was low-43% reported little or none-but support for better protections was high: 97% favored stronger welfare measures and 94% wanted more information. While 92% showed interest in welfare-certified salmon, only 21% were willing to pay up to 5% more. The study underscores the importance of public education and transparency to foster support for sustainable and welfare-conscious aquaculture.
