Potentially new emerging diseases on two species of Indonesian freshwater aquaculture: giant gourami (Osphronemus gourami) and Asian catfish (Pangasius hypophthalmus)

Disease outbreaks and mortality in giant gourami and Asian catfish (pangasius) culture have been frequently reported during the last decade. Etiological agents of the disease have remained unknown, so it is needed to explore epidemiological studies to know the main causative agents. The study aimed...
