摘要：Themorphological characteristics of embryonic developmentwere observed in diploid crucian carp Carassius auratusauratus(2n♀×2n♂,DD)and silver crucian carp C.auratusgibelio(3n♀×3n♂,SS)in Heilongjiang River.The SS(DD)had yellow round adhensive mature eggs with transparentmembrane,and egg diameter of 1.3-1.7 mm(1.2-1.6 mm).The fertilized eggs from SS(DD)developed into cleavage stage 1 h 08 min(1 h 03 min)after fertilization at(23±1)℃.At the same conditions,blastula stage appear 2 h 54 min(5 h 02 min)after fertilization,gastrula stage appear 8 h 06 min(6 h 49 min)after fertilization,neurula stage was observed 10 h 25 min(10 h 51 min)after fertilization,organogenesis stage was noticed 14 h 22 min(16 h 20 min)after fertilization, and hatching stage was observed 59 h 31 min(59 h 05 min)after fertilization.The findings indicated that SS and DD had normal early embryonic development,provided an evidence to understand the genetic background and reproduction for SS and DD.
