After mating, the female burrows into the flesh of a fish and transforms into an unsegmented, wormlike form, usually with a portion hanging from the fish's body. [1] Eggs are released from the posterior "tails" (egg sacs) into the water, where they hatch within 24 to 36 hours. [ 2 ]
Cryptocaryon irritans is a species of ciliates that parasitizes marine fish, causing marine white spot disease or marine ich (pronounced ick). [ 1 ] [ 2 ] It is one of the most common causes of disease in marine aquaria .
In most aquarium tanks, the fish are at high concentrations and the volume of water is limited. This means that communicable diseases can spread rapidly to most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental ...
The best preventive measure for Anisiakis is to avoid eating raw or undercooked fish or squid. [20] Another common prevention method is the thermal treatment of the fish or squid prior to consumption. The fish or squid should be cooked at >60 °C for >1 min or frozen whole at −20 °C for >24 h. [21]

The Anisakis simplex is a parasitic roundworm classified under the phylum Nematoda. [2] [5] It possesses the typical characteristics of its phylum, including an unsegmented, cylindrical body that occasionally fills up with fluids and allows it to swim freely. [5]
An effective way to clear Ich from a fish population is to transfer all of the fish carrying trophonts in their skin, fins or gills to a non-infected tank every 24 hours. Then the fish do not get re-infected and after a number of days (dependent on temperature) the fish have cleared the infection because trophonts exit within this period.
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]
