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 ...
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 ...
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.
The parasite then replaces the fish's tongue by attaching its own body to the muscles of the tongue stub. [7] The parasite apparently does not cause much other damage to the host fish, [2] but Lanzing and O'Connor (1975) reported that infested fish with two or more of the parasites are usually underweight. [8]
The motile cercaria larva is released by the first intermediate host, typically a snail, and parasitizes a second intermediate host, where it encysts into a metacercaria. Finally, the adult flatworm typically inhabits the alimentary system or other body cavity of a fish. [3] The families of Bucephaloidea are Bucephalidae and Nuitrematidae. [4]
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]
Females now measure about 20 mm long, but can grow up to 50 mm. [6] The oral end of the female copepod penetrates the body of the cod until it enters the rear bulb of the host's heart. There, firmly rooted in the cod's circulatory system, the front part of the parasite develops in the shape of antlers or branches on a tree, reaching into the ...
One of the species in this genus is Acanthocephalus anguillae (Mueller, 1780), [citation needed] a fish parasite. Acanthocephalans are also found in humans and primates, causing a common zoonotic infection called "human acanthocephaliasis". While pathogens can be transferred among animals and humans, the main source of human acanthocephaliasis ...
