The Complex Influences on How We Care for Farmed Fish

Area of Science:

• Aquaculture
• Animal Welfare
• Behavioral Science

Background:

• Fish welfare has improved inconsistently across aquaculture systems and species.
• Barriers to progress include lack of clear messages, dissemination, and cost, but these are not the sole reasons.
• Farmer intentions and academic research have not fully translated into improved fish care.

Purpose of the Study:

• To explore why improvements in farmed fish care have been inconsistent.
• To apply human behavioral theory as a framework for enhancing fish welfare.
• To provide practical guidelines for influencing farmer behavior to improve fish care.

Main Methods:

• Review of existing literature on fish welfare and aquaculture practices.
• Application of human behavioral theory concepts to on-farm care scenarios.
• Case examples illustrating the use of behavioral theory in aquaculture.

Main Results:

• Inconsistent progress in fish welfare is linked to complex factors beyond simple knowledge or cost barriers.
• Human behavioral theory provides a conceptual framework to understand and modify farmer practices.
• Targeting farmer behavior, rather than just providing information, is key to improving fish care.

Conclusions:

• Human behavioral theory offers a powerful lens for understanding and improving farmed fish welfare.
• Practical application of behavioral principles can bridge the gap between good intentions and effective fish care.
• Future efforts should focus on behavior-change strategies to enhance aquaculture animal welfare.
