Dropsy is a condition in fish caused by the buildup of fluid inside the body cavity or tissues. As a symptom rather than a disease in its own right, it can indicate a number of underlying diseases, including bacterial infections , parasitic infections, or liver dysfunction.
Fish gills are also the preferred habitat of many external parasites, attached to the gill but living out of it. The most common are monogeneans and certain groups of parasitic copepods, which can be extremely numerous. [18] Other external parasites found on gills are leeches and, in seawater, larvae of gnathiid isopods. [19]
Glugea is a genus of microsporidian parasites, predominantly infecting fish. [1] Infections of Glugea cause xenoma formation. [1]Currently, Phylogenetic tree of this genus seem unreliable, as not enough evidence is present, [1] therefore species with their common hosts are given in a list:
Spring viraemia of carp virus has been shown to infect a wide variety of fish species including silver carp, grass carp, crucian carp, and bighead carp.It has also been shown experimentally to infect other fish species including northern pike, guppies, zebrafish, and pumpkinseed. [1]
Henneguya zschokkei is found in fish as an ovoid spore with two anterior polar capsules and two long caudal appendages. [6] Individuals are very small (about 10 micrometers in diameter), [7] but are found aggregated into cysts 3–6 mm in diameter at any place in the animal's musculature.
Diarrheic shellfish poisoning (DSP) is one of the four recognized symptom types of shellfish poisoning, alongside paralytic shellfish poisoning, neurotoxic shellfish poisoning and amnesic shellfish poisoning.
Kudoa thyrsites is a myxosporean parasite of marine fishes.It has a worldwide distribution, and infects a wide range of host species. This parasite is responsible for causing economic losses to the fisheries sector, by causing post-mortem "myoliquefaction", a softening of the flesh to such an extent that the fish becomes unmarketable.
This pathology is temperature dependent and occurs usually when water temperatures rise above 18-20 °C. Below this temperature, fish can harbour the pathogen as subclinical infection and become carriers for long time periods (Romalde, 2002) [incomplete short citation].
