Fish health checks are carried out to help protect fish and the water environment from harmful parasites and diseases.

The examination is based on a representative sample of the fish to be stocked being selected for a health check. The check involves an internal and external examination to look for parasites and signs of disease.

A health check will not guarantee fish are disease free, but it greatly reduces the risk of introducing anything harmful to fisheries and the environment.

Do I need a health check?

Health checks can be either ‘Mandatory’ or ‘Non-mandatory’. Mandatory health checks as required by the Environment Agency (EA) were formerly known as ‘Section 30’ health checks, this legislation has been replaced with new fish movements legislation, which is “The Keeping and Introduction of Fish (England and River Esk Catchment Area) Regulations 2015”. (KIF) This legislation is also regulated by the EA.

The examination of the fish is carried out to provide for the requirements of the site permits issued to fisheries under the ‘KIF’ legislation. The fishery owner will know from their site permit if their site is considered to be ‘Mandatory’ or ‘Non-Mandatory’

When the EA through the fisheries site permit site does not require a Mandatory health check it is respectfully suggested that the risk from disease does not become less it simply becomes your risk alone.

AGA is here to help with good advice should wherever possible be evidence led so a health check and report is a great place to start, it will offer peace of mind that the fish 9your investment is suitable and ‘fit for purpose’.

Fish health checks are valid for:

  • 6 months for coarse fish

  • 12 months for farmed trout and salmon

What fish should I submit for a health check?

The fish you select for a health check must be representative of the fish that will be stocked. There are rules about the species, number, and size of fish that need to be examined (known as ‘Fish size rules for health checks’).

  • 5 fish from each size category of species intended for stocking

You can deliver the fish to us yourself, or use a courier.
