From Land to Water: Taking Fish Welfare Seriously

Area of Science:

• Animal Welfare Science
• Aquaculture Science
• Comparative Vertebrate Studies

Background:

• Significant expertise exists in terrestrial vertebrate welfare.
• Fish welfare research, particularly in aquaculture, requires more robust methodologies.
• Previous research in terrestrial animal welfare offers valuable insights and lessons.

Purpose of the Study:

• To evaluate the current state of knowledge on fish welfare using terrestrial animal welfare science as a framework.
• To identify challenges and opportunities in studying fish welfare.
• To propose strategies for advancing fish welfare research and addressing knowledge gaps.

Main Methods:

• Applying established principles and methodologies from terrestrial animal welfare science to fish.
• Comparative analysis of research approaches between terrestrial and aquatic species.
• Identifying and adapting relevant scientific questions and investigative techniques.

Main Results:

• The study highlights the potential for significant advancements in fish welfare assessment by integrating terrestrial animal welfare science.
• Key challenges in fish welfare research include species-specific differences and methodological limitations.
• Opportunities lie in adapting successful strategies from terrestrial studies to aquatic environments.

Conclusions:

• A transdisciplinary approach, integrating terrestrial animal welfare science, is crucial for enhancing fish welfare in aquaculture.
• Further research is needed to refine methodologies and fill critical knowledge gaps in fish welfare.
• Implementing evidence-based strategies can improve the welfare of farmed fish species.
