Chondracanthidae is a family of parasitic copepods, usually found infecting the branchial chamber of demersal fishes. It comprises the following genera: [1]
Siphonostomatoida is an order of copepods, containing around 75% of all the copepods that parasitise fishes. Their success has been linked to their possession of siphon-like mandibles and of a "frontal filament" to aid attachment to their hosts. Most are marine, but a few live in fresh water. There are 40 recognised families:
Ergasilidae is a widespread family of copepods and comprises many species. The type genus is Ergasilus. With a few doubtful exceptions all ergasilids are parasitic on fishes.
Taeniacanthidae is a family of cyclopoid copepods in the order Cyclopoida. There are more than 20 genera and 120 described species in Taeniacanthidae.
Pennellidae is a family of parasitic copepods. When anchored on a host, they have a portion of the body on the outside of the host, whereas the remaining anterior part of the parasite is hidden inside tissues of the host.
Caligus is a genus of sea lice in the family Caligidae. The species are parasites of marine fishes and could be vectors of viruses. As of 2017, the World Register of Marine Species includes the following species:
The Bopyridae are a family of isopod crustaceans in the suborder Cymothoida. There are 1223 individual species contained in this family. Members of the family are ectoparasites of crabs and shrimp. They live in the gill cavities or under the carapace where they cause a noticeable swelling. Fossil crustaceans have occasionally been observed to have a similar characteristic bulge.
Hamaticolax is a genus of parasitic copepods belonging to the family Bomolochidae. Its members can only be distinguished from the closely related genus Acantholochus by the presence of an accessory process on the claw of the maxillipeds. It includes the following species:
Lernaeopodidae is a family of parasitic copepods. The females are typically large and fleshy, and attach to the host permanently using a plug made of chitin called the bulla. The males cling on to the females using their antennae. They parasitize both marine and freshwater fish. Some lernaeopodids, including Clavella and Salmincola, can have negative impacts on fish in aquaculture.
Acanthochondria limandae is a species of copepods in the genus Acanthochondria. They are host-specific ectoparasites of two species of flatfish: the common dab and the European flounder. They attach themselves to the bases of the gill arches of their hosts. They can infest as much as 2 to 30% of fish in a given population.
Chondracanthus is a parasitic copepod genus in the family Chondracanthidae, containing the following species:
Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.
Acanthochondria is a genus of copepods, containing the following species:
Lepeophtheirus is a genus of sea louse. The best-known species is L. salmonis, the salmon louse. Other species include L. pectoralis, which uses flatfish as its host, particularly the European flounder, and is also the type species of the genus Lepeophtheirus.
Decemtestis is a genus of trematodes in the family Opecoelidae. It has been synonymised with Allodecemtestis Hafeezullah, 1970.
Peniculus is a genus of marine copepods in the family Pennellidae. They occur worldwide and typically parasitize coastal or epipelagic fish, with the exception of Peniculus hokutoae that was found parasitizing a mesopelagic myctophid, Symbolophorus evermanni.
