How to get your fish health checked

The Environment Agency requires that all Section 30 movements of fish to Mandatory* waters must be supported by a health check.

*Mandatory waters are open waters (rivers, canals and drains), stillwaters connected to an open water or within the floodplain.

When do I require a health check?

When you apply to introduce fish into a Mandatory water the Environment Agency Officer assessing the application will ask to see a current health check. Health check may sometimes be needed for Non-Mandatory waters (fully enclosed stillwaters), where there are special ecological concerns.

Who can carry out health checks for me?

Health checks are done by approved Independent Fish Health Consultants. It is important that you contact the consultant well in advance of the planned introduction to arrange the health check. The demand for health checks can be very high at certain times of the year.

How many fish should be checked and of what size?

Detailed information on the number of fish and size ranges are contained in Rules for fish submissions for Section 30 health checks.

How do I submit fish for a health check?

You can deliver fish to the consultant in person or by courier. Some fish health consultants will examine the fish at the waterside or at other premises.

Anyone transporting fish may have to comply with the Welfare of Animals (Transport) Order 2006. Depending on the type and length of journey, the Order requires that you take certain measures to protect the fishes' welfare. Please see Defra's website for details. You should ensure that the courier you use has a Defra licence for moving fish under this legislation.

Fish sent by courier should be transported in boxes in well-sealed high-grade polythene bags, with just enough water to cover the backs of the fish. The bag should then be inflated with air or oxygen, if available. During warmer months freezer blocks can be added to the outside of the bag. The box should be clearly marked "Live Fish". The following details should be included in the box: • Source water of the fish • Species enclosed • Your name and details



Correctly packaged fish can be transported overnight without problems. The couriers will charge for this service, depending on the number and total weight of the boxes. Further information on transporting fish for health checks can be given when booking samples with the consultant or by the National Fisheries Laboratory.

Do I need a health check when stocking other waters?

If the water you plan to introduce fish to is non-Mandatory (fully enclosed stillwaters only) you will not automatically require a health check. However, the Environment Agency strongly recommends that you get the fish health checked to protect your fishery.
