A Preliminary Report on Hybridization and Growth Comparison Experiments of Schizothorax chongi(♀)and Percocypris pingi pingi(Tchang)(♂)
To investigate the feasibility of the crossbreeding between Schizothorax chongi and Percocypris pingi pingi(Tchang),evaluate the growth advantage between hybrids and original progenies,and provided theoretical reference for crossbreeding between Schizothorax chongi and Percocypris pingi pingi(Tchang),laying a foundation for the development and utilization of Schizothorax chongi and Percocypris pingi pingi(Tchang),a crossbreeding experiment was conducted.Artificial breeding including spawning,fertilization and fry rearing were carried out by using Schizothorax chongi as maternity and Percocypris pingi pingi(Tchang)as paternity.We also measured morphological data of hybrids and Schizothorax chongicry.Finally,a total of 14300 hybrids were obtained with fertility and hatching rate was 82.8％and 73.4％,respectively.Morphological analysis showed that the significant growth advantage for hybrids was exhibited from one year old.In this study,we verified the possibility of the crossbreeding between chizothorax chongi(♀)and Percocypris pingi pingi(Tchang)(♂).
