Reliable identification of crayfish plague is vital for Finland’s crayfish populations
The Finnish Food Authority has discovered a previously unknown species of water mould in noble crayfish in a small Finnish lake, similar to that which causes crayfish plague. This water mould resembles crayfish plague, an invasive species in Finland, so closely that it may compromise the reliability of crayfish plague studies. The discovery of this new species shows that disease identification methods must be continuously improved to guarantee their reliability.A Finnish species of water mould, Aphanomyces fennicus sp. nov., is so closely related in its genome to the water mould that causes
