Basic introduction of Pengze carp

Pengze carp, also known as Luhua carp or Pengze big carp. Pengze crucian carp is native to the natural waters of Pengze County, Jiangxi Province. Pengze crucian carp, known as reed flower crucian carp due to its frequent habitat in the reeds of the lake, has 5-7 gray black reed like markings on its side; It is known for its large size (with a known maximum individual weight of 6.5 kilograms), hence it is called the Pengze big carp. After breeding, the growth rate of Pengze crucian carp is 50% faster than before breeding and 249.8% faster than that of ordinary crucian carp. Due to its excellent traits such as easy reproduction, fast growth, large size, strong stress resistance, and high nutrition, Pengze crucian carp has been widely promoted for breeding in most parts of the country, and a complete set of fish fry breeding, seedling cultivation, and adult fish breeding technologies have been formed, achieving significant economic and social benefits

Feeding management:

After the fish fry are put into the pond, they should be supplemented with organic fertilizer or fed with soybean milk according to the water quality. According to the growth of the fish, feed them with soybean cake powder, fine wheat flour, rice bran and other baits. After about 20 days of cultivation, they can grow into summer flowers of about 3 centimeters

Summer flowers are cultivated into large-sized fish species, which require feeding with full price mixed pellet feed with a protein content of over 30%, a feed coefficient of 1.4-1.7, a particle size of 0.2-2.0 millimeters, with a smaller size in the early stage and a larger size in the later stage. The daily feeding rate is about 8% for domestication feeding of fish. After about 15 days of training, the group can float up and grab food. The feeding amount should be flexibly controlled according to the water temperature, weather conditions, water quality, and fish feeding situation

The main goal is to strengthen water quality management, maintain a transparency of 25-30 centimeters in the pool water, and ensure that the pool is well nourished, lively, tender, and refreshing. During the cultivation of fish species, especially during the high temperature season, it is necessary to regularly replace the water with new water to prevent excessive water quality. Inject new water once every 20-25 days, 10-15 centimeters each time, and change the water once every 7 days, 15-20 centimeters each time. During the breeding process, when the transparency is greater than 30 centimeters, timely fertilization should be applied, with the principle of "less application and more frequent application". 50 kilograms of organic fertilizer or 3 kilograms of urea can be applied per acre. Every half month, the entire pond is sprayed with quicklime to improve water quality, with 15 kilograms of quicklime per acre. Regularly prevent and treat diseases

Breeding Techniques

Pengze crucian carp parent fish should choose mature individuals with a body weight of over 200 grams, strong physique, no injuries, and typical characteristics. The optimal size for the spawning pool is 0.6-1 acres. 7-10 days before induction of labor, clean and disinfect the spawning pool, then add about 70 centimeters of deep water, and strictly prevent wild fish from entering the spawning pool. Tie a fish nest with palm bark or willow roots, soak and disinfect it with 10-20 grams/cubic meter, and dry it in the sun for later use. It can be artificially induced or naturally laid during reproduction. Artificial induction of labor involves injecting 800-1200 international units of chorionic gonadotropin or 20-30 micrograms of luteinizing hormone releasing hormone analogs per kilogram of female fish. The injection dose for male fish is halved. Adopting a one-time injection for induction of labor, the injection site is usually at the base of the pectoral fins without scales. When the water temperature for inducing labor in Pengze carp is between 18-20 ℃, the effect time is 9-16 hours, and the entire spawning process lasts for 6-20 hours. The hatching method of fertilized eggs is the same as other crucian carp. Natural reproduction involves placing selected male and female parent fish in a certain proportion into the same cleaned and disinfected spawning pool. When the weather is clear and the water temperature is suitable, if the parent fish is found to be in heat, a fish nest should be immediately set up to allow them to lay eggs and reproduce on their own. This method is simple and easy to implement, suitable for small-scale production. The main disadvantages are long egg laying cycle, inconsistent emergence time, and inconvenience for feeding and management in the next stage
