2000) reported that variations in the infection parameter of anisakids in fish species are related in part to the presence of definitive hosts, environmental factors, such as temperature, that influence the development of the parasite eggs, populations of intermediate or paratenic host crustaceans, as well as the age, size and feeding habits of the fish.
