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).
Parasites of coral reef fish include nematodes, Platyhelminthes (cestodes, digeneans, and monogeneans), leeches, parasitic crustaceans such as isopods and copepods, [52] [53] [54] and various microorganisms such as myxosporidia and microsporidia. Some of these fish parasites have heteroxenous life cycles (i.e. they have several hosts) among ...
Diphyllobothrium is a genus of tapeworms which can cause diphyllobothriasis in humans through consumption of raw or undercooked fish. The principal species causing diphyllobothriasis is D. latum, known as the broad or fish tapeworm, or broad fish tapeworm. D. latum is a pseudophyllid cestode that infects fish and mammals.
Cymothoa exigua, or the tongue-eating louse, is a parasitic isopod of the family Cymothoidae.It enters a fish through the gills.The female attaches to the tongue, while the male attaches to the gill arches beneath and behind the female.
After the infected meat has been eaten, the larvae are released from their cysts in the stomach. [1] They then invade the wall of the small intestine, where they develop into adult worms. [1] After one week, the females release new larvae that migrate to voluntarily controlled muscles, where they form cysts. [1]
The common name "grouper" is usually given to fish in one of two large genera: Epinephelus and Mycteroperca. In addition, the species classified in the small genera Anyperidon, Cromileptes, Dermatolepis, Graciela, Saloptia, and Triso are also called "groupers". Fish in the genus Plectropomus are referred to as "coral groupers". These genera are ...
Anisakis simplex, known as the herring worm, is a species of nematode in the genus Anisakis. Like other nematodes, it infects and settles in the organs of marine animals, such as salmon , mackerels and squids .
Columnaris disease in young fish is acute and damages the gills, leading to death by respiratory distress. [1] In chronic cases, fin rot, or frayed and ragged fins, can appear. Lesions begin at the base of the dorsal fin on the back of a fish and spread over time, hence the name saddleback disease. Ulcerations on the skin, and subsequent ...
