The embryonic development characteristics of Percocypris pingi pingi（Tchang）were studied，under the water temperature 18±0.5℃. The results showed that the fully mature eggs were spherical，aurantium，sticky， 2.2 mm in diameter，and 3.2-3.8 mm after absobing water. When water temperature was 18±0.5℃，126 hours and 28 minutes was needed to hatch the embryos，which were described as follows：fertilized egg at 0 minute，2-cell stage at 2 hours and 28 minutes after fertilization，after fertilization 45 hours and 23 minutes organs begin to form， and larvae at 126 hours and 28 minutes after fertilization. Newly hatched larvae have a total length of 10.4 mm， yolksac was big and compressed. The embryonic development process could be divided into 7 stages，including fertilized egg stage，cell division stage，blastula stage，gastrula stage，neurula stage，organ formation stage and hatching stage. They contained thirty—two developing phases，whose characteristics were described in detail．
