Ligula intestinalis is a tapeworm of fish, fish-eating birds and copepods, with species from each group featuring in its complex life cycle. [1] Ligula intestinalis is a parasite that changes its intermediate host's behavior to become more vulnerable to its predators.
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 ...
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 ...
The parasite is 0.5 mm (0.02 in) long, [2] and cannot be seen with the naked eye, but it can be seen with a magnifying glass. [6] On its posterior end is a haptor, a specialized organ for attaching to the host fish, which has sixteen hooks around its edge. [2] The parasite is viviparous, that is, it produces live offspring.

One of the most effective procedure is called the salt bath which is quite effective in eradicating ciliated parasites from the fish. However, there are also useless, thus not recommended, bath treatments such as the use of certain antibiotics or vitamins in the bath. Bath treatment can either be short-term (a "dip") or long-term (from a few ...
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 .
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 ...

[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.
