Fisiologia de los peces triploides

open access: yesLatin American Journal of Aquatic Research, 2016
Triploidy has become a recommended tool for aquaculture since problems associated with gonadal maturation can be eliminated or reduced by producing triploid fish, which are functionally sterile. Although the possibility of sterilizing a large number of individuals has helped for triploidy to become an important issue economically, the physiological ...
