Didymoĭidymo is a freshwater algae that has the appearance of wet toilet paper and the feel of wet cotton wool. Dense colonies of mussels can clog water pipes and make the shoreline unuseable because of their sharp shells and odour. They are very efficient at filtering nutrients from the water, leaving no food for native species. Just a few mussels can produce millions of eggs. Quagga and Zebra mussels are small, fan-shaped, and range from dark brown to white in colour. This disease is not harmful to humans or other mammals but can have significant effects on some fish populations. The disease can be spread to other waterbodies through spores in mud. Whirling disease is caused by a parasite that causes skeletal deformities of an infected fish’s body or head, usually in young fish, and the tail may appear dark or black. We need your help to prevent the spread of invasive species
