Abstract Proliferative kidney disease (PKD) is an emerging disease of salmonid fishes. It is provoked by temperature and caused by infective spores of the myxozoan parasite <I>Tetracapsuloides bryosalmonae</I>, which develops in freshwater bryozoans. We investigated the link between PKD and temperature by determining whether temperature influences the proliferation of <I>T. bryosalmonae</I> in the bryozoan host <I>Fredericella sultana</I>. Herein we show that increased temperatures drive the proliferation of <I>T. bryosalmonae</I> in bryozoans by provoking, accelerating and prolonging the production of infective spores from cryptic stages. Based on these results we predict that PKD outbreaks will increase further in magnitude and severity in wild and farmed salmonids as a result of climate-driven enhanced proliferation in invertebrate hosts, and urge for early implementation of management strategies to reduce future salmonid declines.
