Advanced examination of welfare innovations in halibut aquaculture, including substrate design, low-stress handling systems, and the evidence connecting welfare to product quality.
The welfare-quality connection in halibut is particularly well-documented — stress at slaughter produces measurable product quality degradation through its effects on post-mortem muscle biochemistry. This creates an unusual alignment between welfare and economic interests that halibut farmers can capitalize on. The welfare improvements most likely to be adopted — substrate provision, low-stress crowding, electrical stunning — all have documented product quality benefits alongside their welfare benefits. Leading Norwegian producers who have adopted these practices are achieving premium market positioning based on welfare quality differentiation. This market dynamic may drive welfare adoption more rapidly in halibut than in species where welfare-quality connections are less direct.
