Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to an artificial breeding method of black crucian carp.
Background
Black crucian (Carassius) is fish of Cyprinus of Cyprinaceae. Black crucian carps are naturally distributed in central europe, eastern europe and the like, and are only distributed in the river basin of forehead zisi in China. The black crucian has very strong hypoxia resistance and extremely cold resistance, and can be used as an excellent stock for carrying out hybridization breeding research to culture a new cold-resistant strain. Meanwhile, the black crucian carp grows fast, is an economical fish, is golden in body color, has a strong ornamental value, and can be developed and utilized. In recent years, the resource amount of black crucian carp is sharply reduced due to transitional fishing, environmental pollution, habitat destruction and the like. At present, black crucian carps are difficult to catch in the river basin of the forehead zisi, and are formally listed in the name list of important aquatic wild animals in the autonomous region of Xinjiang.
Therefore, artificial breeding is an effective measure for realizing the resource recovery of black crucian, and documents about breeding and propagation of the black crucian are not reported yet. The current artificial breeding mode of crucian is not suitable for the artificial breeding of black crucian in the aspects of fertilized egg incubation temperature, oxytocic dosage, offspring seed cultivation temperature and the like, so that the induced spawning rate is low, the emergence rate is low, the survival rate is low, and the large-scale production of black crucian offspring seeds cannot be formed. In view of the above, we propose an artificial breeding method of black crucian carp to solve the above problems.
