Tropical Abalone Welfare in Asian Aquaculture

Welfare considerations for tropical abalone farmed in land-based systems across Asia.

Key Facts

Tropical abalone species are farmed in Taiwan, China, and Southeast Asia
They are herbivorous — fed macroalgae or commercial pelleted feeds
Overcrowding causes aggregation stress and reduces growth welfare
Handling frequency and water temperature management are key welfare factors

Welfare Considerations

Tropical abalone welfare in aquaculture is affected by stocking density, water temperature, and handling frequency. Their stress responses to handling are observable through retraction into the shell and reduced activity. Welfare-focused production maintains lower stocking densities, minimises handling, and manages water temperature within the thermal comfort range. Welfare research for tropical abalone is less developed than for temperate species.
