The Chinese carp is found in its original form in Korea, China and Japan. This crucian carp in nature has a Golden hue, especially in shallow, well warmed by the sun waters. 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. Genuine development (in some exotic species) goldfish reached in the Eastern countries.
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. This popularity and widespread fishes contributed to the successful breeding of various breeds, striking beauty, forms and colouring, be sure to see the photos of goldfish. Continue reading
We all know that water is life. Without water can’t live no living creature. And the first life originated in water. Fish one of the many live organisms living in the aquatic environment. They live in the oceans and seas, rivers and lakes. You can see them in the pond and the stream, in the waters of caves and even in puddles. In nature, there are over 25,000 species of fish, and they are divided into two classes: Bony fish (more than 23 000 species); Cartilaginous fishes (9000 species).
To the class of cartilaginous fish include sharks, rays and chimeras. To the class of bony fish include salmon. okuneobraznyh. preobrazenie. clupeiformes. Cypriniformes, catfishes, wildcookie, flatfish, coloscopie.
Fish are cold blooded vertebrates. their streamlined body covered with scales. They breathe with gills, and with the help of fins and tail to swim. Water entering the body through the mouth, passes through the gills, and spilling over her holes. Oxygen enters the bloodstream of fish through the thin membrane of the gills. Do fish have paired fins (pectoral and abdominal), which are located on the sides and unpaired, located on the median vertical plane of the body (back, tail, and anal). Fins help fish to steer, brake, accelerate and keep the balance. Continue reading
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
