How to Carry Out Selective Breeding and Breed Conservation in Jian Carp Farming
Any superior breed, if selective breeding and breed conservation are neglected, will often lead to breed degradation, reduced yield and deterioration of other traits. Jian carp has stable genetic traits and can, through within-breed reproduction, pass the superior traits of this breed on to its offspring. However, different carp breeds easily interbreed and become mixed, individuals within the same breed also differ, and the living environment can have a considerable effect on the traits of a breed. Therefore, attention must be paid to selective breeding of superior stock: according to the breed's standards, fish with good traits in all relevant respects should be selected as broodstock for rearing and allowed to reproduce.
