Aeromonas salmonicida, a Gram-negative bacteria, causes the disease furunculosis in marine and freshwater fish. Streptococcus iniae , a Gram-positive , sphere-shaped bacteria caused losses in farmed marine and freshwater finfish of US$100 million in 1997.
Bacterial cold water disease (BCWD) is a bacterial disease of freshwater fish, specifically salmonid fish.It is caused by the bacterium Flavobacterium psychrophilum (previously classified in the genus Cytophaga), [1] a psychrophilic, [2] gram-negative [2] rod-shaped bacterium of the family Flavobacteriaceae. [3]
Columnaris disease occurs in both wild and farmed freshwater fish and is caused by the bacteria F. columnare. The age of an infected fish impacts the course of the infection. [ 1 ] The bacteria usually enter fish through gills, mouth, or small wounds, and is prevalent where high bioloads exist, or where conditions may be stressful due to ...

Edwardsiella tarda is a member of the family Hafniaceae. [1] [2] The bacterium is a facultatively anaerobic, small, motile, gram negative, straight rod with flagella.[1] [2] Infection causes Edwardsiella septicemia (also known as ES, edwardsiellosis, emphysematous putrefactive disease of catfish, fish gangrene, and red disease) in channel catfish, eels, and flounder.
The following is a list of aquarium diseases. Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed.
Piscirickettsia salmonis is the bacterial causative agent of piscirickettsiosis, an epizootic disease in salmonid fishes. [1] [2] [3] It has a major impact on salmon populations, with a mortality rate of up to 90% in some species. The type strain, LF-89, is from Chile, but multiple strains exist, and some are more virulent than others.
