Among the 46 new hybrid fish species, most of them are closely related hybrids, and interspecific distant hybrids mainly occur within the genus Crucian carp, Cyprinus, Channa, and Siniperca genus, and cross-genus distant hybrids include carp-crucian hybrids and bream hybrids , the distant hybridization across subfamilies is even rarer, and there is only one species of bream hybrid fish, which is a hybrid between the bream subfamily and the bream subfamily. Relatively close, it can be seen that the difficulty is high, and there is no research report on the cross-breeding of the relatively distant Barbae subfamily (Cyprinus genus) and Cyprinus subfamily (Cyprinus genus)

Abstract
The invention provides a sinocyclocheilus grahami and carp hybridization method, and belongs to the technical field of aquaculture. A sinocyclocheilus grahami and carp hybridization method comprises the steps of parent fish breeding, artificial insemination, roe incubation and fry breeding. Parent fish breeding environment parameters and feed types are strictly controlled, good survival conditionsare simulated for sinocyclocheilus grahami and carps, and it is beneficial for the wild sinocyclocheilus grahami and carps to quickly adapt to the artificial breeding environment; meanwhile, use of an oxytocic is avoided, natural sperm production and spawning in the artificial environment are achieved, and ova and sperms with good quality and quantity are provided for artificial hybridization; and meanwhile, key parameters (including the incubation water level, the water temperature, the water flow speed, the pH value, dissolved oxygen, oosperm disinfection and the like) during incubation arelimited, and proper environmental conditions are provided for smooth incubation of oosperms. According to the method, a new hybrid variety which is superior to the carps in meat quality, higher in growth speed than the sinocyclocheilus grahami and high in yield and facilitates artificial large-scale cultivation is cultivated for the high-grade fresh water aquaculture industry.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for hybridizing golden-thread barb and carp in Dianchi Lake. Background technique [0002] The golden-threaded barb (Sinocyclocheilus grahami) in Dianchi Lake belongs to the order Cypriniforms, the family Cyprinidae, the subfamily Barbinae and the genus Sinocyclocheilus, and is also called golden-threaded fish. The golden-threaded barb in Dianchi Lake has the characteristics of tender meat and delicious taste, and has the effects of nourishing yin, regulating essence, warming kidney and replenishing essence. Its value has been recorded in "Da Ming Yi Tong Zhi" and has a long-standing reputation. More than 300 years ago, when Xu Xiake, a great traveler, came to Kunming to visit Dianchi Lake, he described the golden-threaded barb in Dianchi Lake in "Xu Xiake's Travel Notes: A Tour to Taihua Mountain": "The fish is no bigger than four inches, medium fat, wit...
