Abstract: This study is selecting and breeding parent fishes of rdproduction with roe of incubation Period , larva ,fry ,yearling of common carp, crucian carp, grass carp, silves carp and bighead carp irradiated ty low power CO2 laser and TDP infrared and observing breeding capacity of parent fishes selected and breeded , genetic properety interrelated with fry and yearling of the filial generation by parent fishes of male and female irradiated in spawning pond of breeding perioed . Through contrast with thd interrelaeated propernty of parent fishes in the contrasted groups of blank or growing promote agent ,parent fishes irradiated is growing normally,its superiority of breed characterislic is clear ,it is strengthening to its breeding efficiency and resistance in diseases and adversity, its utilizeable to fixed number of years for parent fishes is prolonged. Last it is traced to observe effect at a specified future date in a series of techniques in fishes breed irradiated by low power CO2 laser and TDP as long as ten years ,its appearance of causing deformity, carcinogen and ather genetic degeneration atal. is not discovered about parent fishes, fry and yearling of the filial generation.
