The paper presents review of experimental triploidization trials in percid fishes, important for European aquaculture due to improve and diversification of fish production. The triploidization lead to obtain individuals with three sets of homologous chromosomes (3n) theoretically sterile andshowing a faster growth rate compare to the normal diploid fish. Triploidization in aquaculture isusually performed with the use of thermal/pressure and chemical shocks. Parameters of environmental shocks are species specific and it is extremely important to optimize the exact conditions for procedure. In percids the efficiency of the pressure and thermal shocks is varied, and the survival rate of triploids relatively low. However the production of triploid percids stocks using a pressure shock, can be adapted widespread in the future in the fishery practice
