In laboratory experiments the Tilapia Nilotica irradiated by integrated flux of fast neutrons 1×10 9 neutrons/m2 and 1 ×10 10 neutrons/m2 gave a growth rate more than 40% and 32 % compared with those of controls respectively. The yield of the irradiated Tilapia Nilotica growing with non-irradiated carps and silver carps in a mixed feed condition increased by 8. 6%, 157% and 11. 0% more than those of the controls in the pilot test. The survival rate increases by 21. 8%, 149% and 16. 2% for the aboye-mentioned three species. An increased yield of 52 098 kg fish under irradiation with low dose was obtained in 18. 7 hectare water surface. The results of biological experiments show that the main organic coefficients of the Tilapia Nilotica are greater than those of the controls, and this may be related to the increase of the capabilities of metabolism and resistance to diseases.展开更多
