The product is to be administered by addition to seawater. Immediately prior to administration, mix the correct volume of product with approximately 40 litres of seawater before adding to the seacage at several locations to ensure maximum dispersion.

Preparation of the seacage to be treated: The seacage net should be raised to a depth of 2 – 2.5 metres, and then surrounded by impervious tarpaulins to isolate the cage to be treated. The depth of enclosed water should then be 3 metres. The amount of product to achieve the treatment dose can be calculated using the following table:

An oxygen diffuser should be used during treatment to maintain an oxygen level greater than 7mg/l during the treatment.

1 hour.

0.5ml Excis/m3 sea water, which is equivalent to 5μg cypermethrin/litre sea water.

The treatment may be repeated when re-infestation occurs.
