Defence of doctoral dissertation: Epidemiology of crayfish plague

15.11.2016

The doctoral dissertation studied the occurrence of crayfish plague in Finnish crayfish populations. Crayfish plague is caused by an oomycete Aphanomyces astaci, a North American water mould that grows in the cuticle of the crayfish. When infected, European crayfish usually die quickly. The study found that two types of crayfish plague occur in Finland, one of which has weaker virulence and may remain latent in a weak crayfish population. A persistent infection prevents the permanent recovery of a crayfish population to a productive level.
