Koi is a large-scale noble ornamental fish with red, white, yellow, black, blue, and purple colors. It is characterized by its gorgeous crystal color, beautiful and graceful swimming posture, gorgeous and handsome stripes, and vigorous and aggressive style. More and more loved by consumers. At the same time, it is also a major species in the development of ornamental fish breeding industry in the suburbs of Beijing, which exports to the European market a foreign exchange earner. The following is a brief introduction of the Koi breeding technology as follows:
First, the environmental requirements. Koi is more adaptable to the environment, but it cannot resist the rapid changes in water temperature. When the temperature suddenly drops or rises by 2-3 degrees Celsius, it is easy to get sick. If the temperature rises and falls as high as 7-8 degrees Celsius, the fish will not feed at the bottom of the water. If sudden changes in temperature even more sharply, koi and even death immediately, koi optimal water temperature is 20-25 degrees Celsius life, in which the water temperature, the koi swimming activity, appetite, infirmity, colorful. Koi adapted to living in the slightly alkaline environment of low hardness water, to spring for the best, which contain a variety of mineral elements and other ingredients, can increase the fish pigment, so that koi body color more vivid.
Second, reproductive technology. Koi breeding age is generally 3-8 years of age, weighing more than 1.5 kg. Outer full round selection, round head, body length, no residual deformity, bright color, color uniformity, symmetry shape, no damage, no disease as broodstock fish. From the outside, the female body is short and full-bodied, the abdomen is inflated, and the end of the pectoral fin is rounded. The male body is lean and long, with a slightly pointed tip of the pectoral fin. There are several white “chasing stars†on the first ray of the pectoral fin and the lid of the fin. The reproduction time of the Koi is similar to that of the common carp. Generally, from April to May of each year, when the water temperature is stable above 16 degrees Celsius, the female and male koi can be singled out and put into the prepared pool at a ratio of 1:2. pre-sterilized are placed in the pool good fish nests, spawn let itself, the end of the observation that spawning, the catch from broodstock fish were kept in the pool nest hatch, i.e. 5-7 days hatched fry incubated.
Third, feeding and management. In the courtyard, the hotel directly for the purpose of the construction of cement pond can be built, the pool depth of 0.6-0.8 meters is appropriate, to take a single raising, the density can be slightly larger, can be stocked 3 to 5 per square meter carp, pool or circulation water jets arranged micro-flow conditions, typically twice a day feeding, breeding ornamental fish may be fed brightening specific material, grower, and promote its enriched form a perfect shape. The daily feeding amount is 2% to 10% of the fish's body weight, and it takes 20-30 minutes to finish.
