Fish health checks: before moving fish into inland waters

Imported from official source

Safety Classified by Officially

You must get a fish health check before moving fish into the following types of inland waters:

  • lakes, ponds and reservoirs (stillwaters) with an inlet or an outlet to a river, canal or open water
  • stillwaters within a floodplain which have a 1% chance of flooding in any year, or where there’s evidence of flooding - you can check an area’s long term flood risk
  • Getting a fish health check before moving fish will be a condition of your permit to supply live fish.

    A health check involves an internal and external examination to look for pathogens and signs of disease.

    A health check does not guarantee fish are free of pathogens or disease. But it greatly reduces the risk of introducing pathogens and disease into the environment.

    You may be prosecuted if you do not get a health check before moving fish to a water that requires one.

    Anyone buying or supplying fish should get their health checked before stocking, even if it’s not required by a permit condition.

    You must use an approved fish health consultant to get a fish health check. They are listed at the end of this page.

  • 6 months for all other fish species (including coarse fish and eels)
  • You can deliver the fish to the fish health consultant or use a courier. Some consultants may carry out the check at your fishery.

    If you must provide a health check, you must select a sample of fish that represent the fish you want to move.

    You must keep to the following rules on the:

    The health check must include an examination of at least:

  • 10 fish of each species that you intend to move
  • 5 fish from each size category for each species you intend to move
  • If you only want to move fish in one size category, you can include fish from other size categories of the same species (except fry) to bring the number for that species up to 10.

    Once you have included the minimum numbers of fish required for species and size category, the other fish in the sample can be any species and any size (except fry). All of the fish must be from the same source water.
