Small-scale abalone aquaculture is being developed in the UK, with welfare considerations for this slow-growing gastropod mollusc informing best practice.
Abalone welfare in UK aquaculture development should be considered from the outset as the industry grows. Their slow growth requires multi-year holding in tanks, during which water quality, food availability, and density management all affect welfare. They demonstrate sensory responses to damaging stimuli consistent with nociception. Maintaining appropriate water temperature and quality, providing adequate food, and avoiding overcrowding are the practical welfare interventions most likely to improve outcomes. Establishing welfare standards early shapes industry norms before practices become entrenched.
