Answer 2

Answer:

Epizootic ulcerative syndrome (EUS), also known as mycotic granulomatosis (MG) or red spot disease (RSD), is a disease caused by the water mould Aphanomyces invadans. It infects many freshwater and brackish fish species in the Asia-Pacific region and Australia.

The fungus involved in EUS is also known variously as Aphanomyces invadans, A. piscicida, A. invaderis and ERA

In outbreaks occurring in small, closed water bodies, liming of water and improvement of water quality, together with removal of infected fish, are often effective in reducing mortality. Increasing salinity in holding waters may also prevent outbreaks of EUS in aquaculture ponds.
