Abstract
Establishing the viability of embryos inside the fertilized eggs and the determination of genetic sex to the zebra fish (Danio rerio) was based on the principle of emphasizing the electromagnetic bio-field generated by embryonic cells. The generated electromagnetic bio-field can move a pendulum showing the embryo viability and according to its trajectory (circular or transversal) the genetic sex of embryo or of fry can be established. The studied embryos or fry that generated the transversal movement of pendulum were considered to have male sex, and the studied embryos or fry that generated the circular movement of pendulum were considered to have female sex. The method allows to establish the sex ratio among sexes which was 49.06:50.94. The precision of predicting the genetic sex at 2 weeks at the XY group was 75.38% and to the XX group was of 78.47%. The precision of predicting the genetic sex by emphasizing the electromagnetic biofiled confirmed by establishing the phenotypic sex to the XY group was of 69.66% and to the XX group was 71.05%.

Key words: embryos, sex prediction, electromagnetic bio-field
