They are parasites of fish from freshwater, marine, and brackish water habitat types. [2] The name Bucephalus, meaning "ox head", was originally applied to the genus Bucephalus because of the horn-like appearance of the forked tail (furcae) of its cercaria larva. By what Manter calls a "curious circumstance", horns are also suggested by the ...
Isopod fish parasites are mostly external and feed on blood. The larvae of the Gnathiidae family and adult cymothoidids have piercing and sucking mouthparts and clawed limbs adapted for clinging onto their hosts. [20] [21] Cymothoa exigua is a parasite of various marine fish. It causes the tongue of the fish to atrophy and takes its place in ...
Manual removal of the parasite is one of the surest ways to get rid of it; this can be done by holding the fish in the hand and removing the parasites with a pair of tweezers, being careful not to break the tail off leaving the head embedded and dipping the fish back into water every few seconds so it can breathe. Sometimes the parasite can ...
The predominant groups of cod parasites in the northeast Atlantic were trematodes (19 species) and nematodes (13 species), including larval anisakids, which comprised 58.2% of the total number of individuals. [3] Parasites of Atlantic cod include copepods, digeneans, monogeneans, acanthocephalans, cestodes, nematodes, myxozoans and protozoans: [3]
The parasite can infect most freshwater fish species and, in contrast to many other parasites, shows low host specificity. It penetrates gill epithelia, skin and fins of the fish host and resides as a feeding stage (the trophont) inside the epidermis .
The Bucephaloidea are a superfamily of trematode flatworms, belonging to the large group Digenea.Many species are endoparasites of mollusks and fish.The name Bucephalus meaning "ox head" was originally applied to the genus Bucephalus because of the horn-like appearance of the forked tail (furcae) of its cercaria larva.
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.

An in vitro experiment found that Melafix, as well as the cajeput oil and an emulsifier used in the product tested separately, were as effective against the parasite as the antihelminthic drug Levamisole. An in vivo experiment found Melafix highly effective against the parasite when used in combination with another product from the company ...
