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. Common ...
Parasites can provide information about host population ecology. In fisheries biology, for example, parasite communities can be used to distinguish distinct populations of the same fish species co-inhabiting a region. [9] Additionally, parasites possess a variety of specialized traits and life-history strategies that enable them to colonize hosts.
Due to the low host specificity of the parasite, Ich infection is known from all freshwater fish systems examined. However, the susceptibility and the impact differ between host species. Rainbow trout, catfish and eels are highly susceptible fish species and uncontrolled infections lead to almost 100% mortality.
Oodinium, a genus of parasitic dinoflagellates, causes velvet disease in fish. Velvet disease (also called gold-dust, rust and coral disease) is a fish disease caused by dinoflagellate parasites of the genera Amyloodinium in marine fish, and Oodinium in freshwater fish.
Argulus foliaceus. Argulus foliaceus, also known as the common fish louse, is a species of fish lice in the family Argulidae. [1] It is "the most common and widespread native argulid in the Palaearctic" [2] and "one of the most widespread crustacean ectoparasites of freshwater fish in the world", considering its distribution and range of hosts.

A number of medications and water treatments are used in this way. Salt is the most effective bath treatment, and is used to eliminate ciliated protozoan parasites (including ich in small fish); also used to curb the absorption of nitrite, and to reduce the osmotic pressure exerted by fresh-water on any hole in the skin or gill.
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 ...
Dactylogyrus species are monogenean parasites that are usually found on the gills of cyprinid fishes. [11] The prevalence of Dactylogyrus infection on fish differ depending on the seasons. It was found that Dactylogyrus infections are at their greatest during late autumn or early winter. [ 12 ]
