Yellowtail kingfish is a premium farmed species in Australia, New Zealand, and South Africa with specific welfare needs around water temperature, stocking, and transport.
Kingfish in cage culture face welfare challenges from their active schooling lifestyle. Restricted swimming space at high stocking densities prevents natural movement and causes chronic stress. Temperature excursions during summer heat events cause acute physiological stress and mortality. Live transport for premium sashimi markets involves extended confinement requiring precise environmental management. Pre-slaughter crowding and the welfare of fish during iki jime killing (a traditional Japanese brain-spiking method) are areas where species-specific research has informed improved practice.
