AQUI-S® Versatile Aquatic Anaesthetic

AQUI-S® is a versatile aquatic anaesthetic that has been developed to give flexibility and control in animal husbandry, transportation and harvesting operations. The ingredients are approved for use in foods and AQUI-S® is safe for use in food fish. Fish that are harvested using AQUI-S® have improved flesh quality, greater yield and longer shelf lives. The use of AQUI-S® during the transportation of live fish and during health management practices lowers stress and reduces mortalities.



Consideration of animal welfare is a fundamental and growing requirement in aquaculture. There are many unavoidable activities which can cause extensive stress to aquatic animals, including disease treatment, transport, handling, broodstock stripping, grading and slaughter. AQUI-S® reduces stress during these operations, providing you with strong healthy animals that command a high price at market. Explore our WELFARE section to learn about welfare and how AQUI-S® can help reduce stress and improve quality in your operations.


TRANSPORT: Managing stress during live transport will increase survival and is as easy as adding AQUI-S® to the transport water.


HARVEST: Muscle quality is severely impacted by activity pre-slaughter. AQUI-S® anaesthesia conserves energy and maintains quality.


HEALTH: Stress is a known immunosuppressant and has devastating consequences on recovery, survival and growth.


BROODSTOCK:Stress in broodstock will impact on egg, milt and progeny quality. Manage stress with AQUI-S® for superior results.
