An improper nitrogen cycle, inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental fish in a tank. Despite this, many diseases in captive fish can be avoided or prevented through proper water conditions and a well-adjusted ecosystem within the tank.
The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
VHS disease in a gizzard shad. Viral hemorrhagic septicemia (VHS) is a deadly infectious fish disease caused by Viral hemorrhagic septicemia virus. It afflicts over 50 species of freshwater and marine fish in several parts of the Northern Hemisphere. [1] Different strains of the virus occur in different regions, and affect different species.
Hallmark symptoms of ciguatera in humans include gastrointestinal, cardiovascular, and neurological effects. [5] [6] Gastrointestinal symptoms include nausea, vomiting, and diarrhea, usually followed by neurological symptoms such as headaches, muscle aches, paresthesia, numbness of extremities, mouth and lips, reversal of hot and cold sensation, [7] [8] ataxia, vertigo, and hallucinations.
Trichinosis is mainly spread when undercooked meat containing Trichinella cysts is eaten. [1] Wild meat is more likely to contain the parasite. [7] [8] In North America this is most often bear, but infection can also occur from pork, boar, and dog meat. [9] Several species of Trichinella can cause disease, with T. spiralis being the most common ...
Diphyllobothriasis is the infection caused by tapeworms of the genus Diphyllobothrium (commonly D. latum and D. nihonkaiense).. Diphyllobothriasis mostly occurs in regions where raw fish is regularly consumed; those who consume raw fish are at risk of infection.
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.
A. simplex can cause zoonotic diseases. [7] The consumption or management of raw seafood puts humans at risk for developing an infection or allergic reaction caused by Anisakis simplex. [3] [5] The presence of a single worm in a human's body is enough to cause infection and elicit symptoms. [3]
