The first cleavage of fertilized eggs in rainbow trout is observed by method of histological section,and the tetraploid of rainbow trout is induced by heat shock and hydrostatic pressure.Result shows that hydrostatic pressure is better than heat shock,8h after fertilization,the frequency of occurrence of tetraploid is up to 25~28%,and heat shock induced result was 0%.400min after fertilization,fertilized eggs was at prophase of first cleavage,490min after fertilization,fertilized eggs was at metaphase of first cleavage,640min after fertilization,fertilized eggs was at anaphase of first cleavage,670min after fertilization,fertilized eggs was at telophase of first cleavage,700min after fertilization,the first cleavage ends.
