Latest advances in welfare management for Atlantic salmon in recirculating aquaculture systems (RAS), covering operational welfare indicators, water quality optimization, and emerging best practices.
The latest advances in RAS salmon welfare represent a genuine convergence of technology and welfare science. Real-time monitoring systems that track behavioral and environmental welfare indicators continuously — rather than at scheduled inspection intervals — enable rapid detection and correction of welfare-compromising conditions. The key welfare advance is in moving from reactive management (responding to disease or mortality) to proactive welfare optimization (maintaining conditions that prevent stress). Feed conversion efficiency as a proxy welfare indicator creates economic alignment with welfare improvement. The remaining frontier is translating these operational improvements into certification and regulatory standards that require welfare monitoring across the industry, rather than leaving it as a voluntary advantage for progressive producers.
