Look after our environment - that way it will be there for later generations to enjoy!

 

 Waterborne diseases

 Not all waterborne diseases affect humans. Infections of people with disease causing organisms (pathogens) of animal origin are known as zoonoses. The one most paddlers are likely to have heard of is leptosirosis.

 There are other waterborne diseases that are animal pathogens. Although these are not a threat to humans, they can be devastating to our native river fauna. The newest of these is a salmon parasite called Gyrodactylus salaris. This parasite has not yet reached the UK but is is present in Norway. For more information on Gyrodactylus salaris see the SCA website (see links page)

 

Weil's Disease (leptospirosis)

A bacterial infection carried in rat's urine. A rare disease, more information here.

 

 Blue-green algae

This may affect some of the lakes towards the end of a hot dry summer. If it is a problem follow the advice given locally. (Usually by the National Park Authority).

 

Signal Crayfish

 These have been found in St John's Beck, a tributary of the Greta (and the Derwent). These non-native animals can be up to 30cm long and can be carriers of Crayfish plague which kills native crayfish. The claws are red on the underside as against the native crayfish being dirty white/pink and only up to 12 cm long.

  • After paddling please wash your kit including boat in tap water and allow to dry completely as the plague spores become unviable when dry and Ultra-Violet light kills them.
