Ick saltwater fish

Causes: the Causative agent of this disease is Cryptocarion irritans, which is a kind of analogue of the freshwater “ihti”, parasitic on tropical marine fish. It looks similar to its freshwater counterpart, but smaller (0.5 mm), besides the horse-Shoe macronucleus cryptocaryon malorazlichimyh, while Ichthyophthirius it is visible quite clearly. But the cycles of development and lifestyle of Cryptocarion irritans and Ichthyophthirius multifiliis are the same.

Symptoms: Sick fish dotted with numerous, with a diameter of 0.5 mm, white small knobs. The infestation appears first on the fins, and later goes to the body.

Current: Cryptocarion irritans infects the gills and skin of marine fish. The causative agent is under the top layer of the epithelium is filled with a gelatinous mass of leathery bag.

This pathogen, due to the same lifestyle, same causes harm to as Ichthyophthirius multifiliis.

Treatment: Can be recommended transplanting method, ultraviolet irradiation or chemotherapy, as with Ichthyo – phthirius. Effective there is also treatment with 1.5 mg/l of copper sulfate. With all these methods of treatment will be securely destroyed only free “tramp”, so the treatment should be carried out until, until all parasitise will undergo a full cycle of development. The duration of treatment is heat-dependent (15 days at 27 °C, 20 days at 20 °C), in addition, as in the case of Ichthyophthirius, it depends on the duration of individual phases of development. Daily baths short (5 to 15 minutes) in fresh water for three days travonti will be killed directly on the fish. After that, freed from the parasites of animals 2 weeks should be kept under close supervision in a quarantine vessel. At this time in the main tank of all cysts hatch “tramp” who will die without finding a host. However, this will happen only if there will be no fish.

Prevention: effective prevention can only be recommended 3-week quarantine for all new fish.
