Disinfecting tackle to control fish disease

Methods for disinfecting tackle

Two commonly used disinfection methods to help prevent the spread of fish disease are:

• thoroughly drying equipment for a minimum of 48 hours, preferentially in direct sunlight
• using chemical disinfectants (primarily iodine-based solutions)

Drying in sunlight is preferable, but may not always be practical. In this case, chemical disinfectants can be used.

How to disinfect your tackle

Remove all mud and debris from your equipment.

Immerse or spray with your preferred disinfectant. Leave the chemical on for at least 10 to 15 minutes.

Rinse off the disinfectant with clean water. Dispose of disinfectant washings in a way that does not harm the environment - never tip it into water containing fish or other aquatic life.

Some disinfectants may contain hazardous chemicals. It's important that you follow product labels and manufacturers instructions.

Wear protective clothing and equipment when you dilute disinfectants to protect your eyes and skin. If in doubt seek advice from the suppliers. Manufacturer's guidance on disposal should also be followed.

Disinfectant chemicals

When active, iodine based products (iodophors) are a dark brown solution, however they become colourless when inactivated by prolonged exposure to light.

Dilution of iodophors varies between products so you should always follows manufacturer’s guidelines.

Follow good biosecurity measures

Good biosecurity measures are key to keeping our rivers and fisheries healthy.

Invasive plants and animals harm the environment, reduce the quality of fishing and spread disease.

Help to stop the spread of diseases by following the Check, Clean, Dry code.
