The vast majority of the squad are classic carnivores, hunting mainly vertebrates. Predatory sometimes is also divided into two groups that are very different from each other in their mode of life: terrestrial Carnivora ( Fissipedia ) and pinnipeds ( Pinnipedia )

Goldfish as a domesticated form of carp, judging by some reports, developed in Korea where, apparently for the first time, these taking advantage of the variability of carp in coloration and body shape, engaged in the culture of ornamental carp.

Bred goldfish in ponds and garden ponds in the estates of the nobility and wealthy people. Further spread of the goldfish was facilitated by itinerant hawkers. In buckets on the rocker arms they carried the fish through towns and villages. Thus goldfish broke into the homes of ordinary people. Fish were kept in wooden, glass and porcelain vessels, which are the predecessors of modern domestic aquaria.

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. Continue reading
