Parasites in fish are a common natural occurrence. 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]
Glugea is a genus of microsporidian parasites, predominantly infecting fish. [1] Infections of Glugea cause xenoma formation. [1]Currently, Phylogenetic tree of this genus seem unreliable, as not enough evidence is present, [1] therefore species with their common hosts are given in a list:
The larvae of these worms can cause anisakiasis when ingested by humans, in raw or insufficiently cooked fish. Anisakidae worms can infect many species of fish, birds, mammals and even reptiles. [1] They have some traits that are common with other parasites. These include: spicules, tail shapes and caudal papillae. [2]

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 .
These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
There are 52 species of Cryptobia known from fish. 40 of these live in the blood, 7 in the gut, and 5 on the body surface. [1] Examples include: Cryptobia branchialis, an ectoparasite that lives on the skin or gills. It can deform the skin and cause anorexia and death.
