Bairong crucian carp: High-tech: The company has been tackling key problems for six years, and it is the first new tetraploid gynogenetic crucian carp variety bred from triploid through cell engineering technology in China, and has applied for relevant national patents. The growth rate is fast: the interplanting grows to 0.8 kg in that year, and the special fish pond for interplanting can reach 1 kg in that year. The growth rate is better than that of high-yield crucian carp, allogynogenetic crucian carp and Pengze crucian carp, and the growth rate is increased by 30%, with long body shape, less intermuscular thorns, thick back meat and small visceral mass, which is increased by 40%. The scales are compact and transport-resistant: the scales are neat and compact, which is beneficial to long-distance transportation. No sporozoite: After strict technical treatment, the fry itself does not carry sporozoite pathogens. Zhongke No.3 crucian carp is the third generation new variety of allogynogenetic crucian carp. Generally, the fry can grow to about 200-250g in that year, and the big fry can reach more than 400g ... It has the following characteristics: 1 and the growth speed of Zhongke No.3 crucian carp is faster and the meat yield is higher, which is about 3.7-34.4% faster than that of Gaobei crucian carp, and the meat yield is more than 6%. 2. Genetic traits are very stable, and the traits of offspring are not separated from their parents. The scales on the fish are very tight, and it is not easy to fall off. 4. The probability of iodophor infection is low and the survival rate is high. 5. It has a wide range of adaptation to water temperature, and can basically overwinter safely all over the country. The suitable water temperature for growth is 25-30℃. 6. Miscellaneous eating habits, that is, you can eat zooplankton and phytoplankton, as well as benthic animals and plants and organic debris (rotifers are the main fry below 1.5cm, animal food is the main fry above 1.5-3cm, and plant food is the main fry above 3cm).
