Aquaculture is the fastest growing animal food production sector in the world and is an increasingly important contributor to global food supply.

In aquaculture, diseases caused by the fungal-like oomycete Saprolegnia, but also ectoparasites are causing significant declines in fish and crayfish populations. To date, these diseases are controlled in aquaculture mainly by formalin treatment.

Methanotrophic bacteria are crucial in the regulation of methane concentration in the atmosphere and therefore for regulating our climate.
