Developing reliable welfare indicators for farmed salmon is transforming the industry's ability to monitor and improve fish welfare across production cycles.
Salmon welfare in aquaculture is a rapidly evolving field that has moved from philosophical debate to practical measurement. High rates of cataracts indicate chronic dietary deficiencies affecting millions of fish per production cycle. Sea lice, gill disease, and physical injury all have measurable welfare costs. The development of validated welfare indicators allows producers to identify problems earlier and regulators to enforce minimum standards. The shift from anecdotal quality metrics to evidence-based welfare assessment is a significant step forward.
