| Abstract: | In view of some of the characteristics of their sex determination, aquatic animals have an important significance as the objects of both genetic study and breeding practice. Many controlling of sex in aquatic animals can be attained by the application of chromosome engineering, physiological and biochemical techniques. There are many detailed reviews concerning the genetic breeding of aquatic animals at home and abroad. This paper is intended to expound the progress on the studies and application of sex control in aquatic animals, which includes the techniques in induced polyploid, and so on |
