Sea cucumbers are increasingly farmed for food and traditional medicine markets, particularly in Asia. Their welfare is rarely discussed, but basic principles of humane aquaculture apply to these unusual invertebrates.
The welfare status of sea cucumbers is poorly understood, and their phylogenetic distance from vertebrates means their capacity for suffering is uncertain. However, their evisceration response to stress suggests a significant physiological reaction to noxious stimuli. Good aquaculture practice minimizes stress through stable water quality, appropriate stocking densities, and careful handling. Rapid processing methods that minimize time between harvest and death reduce potential suffering. As the industry expands, incorporating welfare principles as a precautionary measure is both ethically defensible and consistent with emerging best practices for invertebrate aquaculture.
