Advanced welfare analysis of halibut aquaculture, examining stress physiology, behavioral indicators, optimal tank design, and emerging welfare assessment frameworks for this large farmed flatfish.
Advanced halibut welfare science is providing increasingly specific guidance for optimizing farming conditions beyond basic survival to genuine quality of life for individual fish. Halibut are active, perceptive fish whose welfare is shaped by multiple environmental parameters that well-designed facilities can control. The combination of appropriate substrate, controlled lighting, careful feeding system design to reduce aggression, minimized handling events with adequate recovery protocols, and pre-slaughter stunning creates conditions where commercial production and individual fish welfare are genuinely compatible. The challenge is translating welfare science into industry standards that are adopted broadly rather than only by the most progressive producers.
