Check Clean Dry
As a water user, you may unknowingly spread invasive species from one water body to another in equipment, shoes and clothing.
Contaminated gear (e.g. equipment, boats, footwear, and clothing) is one of the most common causes of the spread of invasive species to new waterways. Invasive plants and animals can be small and hard to spot so are easily spread on damp equipment and clothing. All water users can protect our wildlife and environment following the Check Clean Dry method. A range of guidance and awareness raising materials for anglers, boaters, canal users, paddle sport enthusiasts and other water users have been developed.
Help stop this happening by following three simple steps when you leave the water.
 |
CHECK – for what’s visible
Check your gear, clothing and footwear after leaving the water for mud, aquatic animals, or plant material. Remove anything you find and leave it at the site. Remember to drain water from every part of your boat and trailer before leaving the site. |
 |
CLEAN – for what’s not visible
Clean everything thoroughly as soon as you can. Pay particular attention to nets, waders, and areas that are damp and hard to inspect. If possible, use hot water (at least 45oC) or a high-pressure spray. Hot tap water in most homes is usually set to about 55oC. |
 |
DRY – to be sure
Dry everything for as long as you can before using in other water bodies. Some invasive plants and animals can survive for over two weeks in damp conditions. The hull of a boat and tailer can dry when being towed. |
Crayfish plague
Crayfish plague is not resistant to desiccation. Therefore, thorough drying of equipment (>24 hours) can be an effective biosecurity measure for crayfish plague.
Crayfish plague is known to be inactivated by a short exposure to temperatures of 60°C or to temperatures of –20°C (or below) for 48 hours (or more) (Oidtmann et al., 2002).
Various disinfectants are known to be suitable for crayfish plague. However, all equipment must be cleaned prior to disinfection since organic matter decreases the effectiveness of disinfectants. Further information can be found on this article: Practical disinfection chemicals for fishing and crayfishing gear against crayfish plague transfer
Please always read the label and follow all precautions before using disinfectants.
Going abroad?
It’s even more important to Check Clean Dry if you’re taking your kit abroad to make sure you don’t bring any plants or animals back with you. Make sure everything is clean and has been dried thoroughly before you use it again at home.
