The product is designed to be dissolved in water. Depending on the desired level of anaesthesia, dilute 15 – 20ml per 100 litres of water of the veterinary medicinal product (equivalent to 30-40 mg of benzocaine per litre of water).
Keep the water well oxygenated before exposure of the fish; immobilization usually occurs within a few minutes of immersion.
The maximum exposure time must not exceed 15 minutes. In general, the total exposure time of the fish to the solution should be controlled as there are different levels of tolerance among species and rearing conditions.
For recovery, transfer the anaesthetized fish into clear, well oxygenated water.
Do not feed the fish for at least 48 hours prior to anaesthesia.
