Intensive fish farming and the evolution of pathogen virulence: the case of columnaris disease in Finland, Proc. R. Soc. B Bookmark and Share

Excerpt: [...] We suggest that fish farms provide an environment that promotes the circulation of more virulent strains of F. columnare. This effect is intensified by the recent increases in summer water temperature. More generally, we predict that intensive fish farming will lead to the evolution of more virulent pathogens.
