The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth.

Routes of exposure and infection include ingestion of undercooked meat, drinking infected water, fecal–oral transmission and skin absorption. Some types of helminths and protozoa are classified as intestinal parasites that cause infection—those that reside in the intestines. These infections can damage or sicken the host (humans or other ...
Anisakis species parasitise fish, and marine mammals and when consumed by humans can cause anisakiasis a gastric or gastroallergic disease. [70] Gastrointestinal nematode infections in humans are common, with approximately 50% of the global population being affected.
Several species of Trichinella can cause disease, with T. spiralis being the most common. [1] After the infected meat has been eaten, the larvae are released from their cysts in the stomach. [1] They then invade the wall of the small intestine, where they develop into adult worms. [1]
A. simplex can cause zoonotic diseases. [7] The consumption or management of raw seafood puts humans at risk for developing an infection or allergic reaction caused by Anisakis simplex. [3] [5] The presence of a single worm in a human's body is enough to cause infection and elicit symptoms. [3]
Eustrongylidosis is a parasitic disease that mainly affects wading birds worldwide; however, the parasite's complex, indirect lifecycle involves other species, such as aquatic worms and fish. Moreover, this disease is zoonotic , which means the parasite can transmit disease from animals to humans.
