摘　　要：从１９７６年至１９７９年，辐照鲢、鲤、草、鳙鱼卵共１３５３万粒，先后用５３种不同剂量，辐照５０余次。中子注量在（１．８±０．０９）×１０￣５至（７３．４±３．６７）×１０￣５ｃｍ￣（－２）之间进行试验，选出较好的剂量，鲢鱼为９．２×１０￣５ｃｍ￣（－２）、鲤鱼为１８×１０￣５ｃｍ￣（－２）、草鱼为１４．４×１０￣５ｃｍ￣（－２）、鳙鱼为１０×１０￣５ｃｍ￣（－２）。鱼卵胚胎发育期为原肠中期时进行中子辐照。成鱼生长实验选用经镭－铍中子源辐照促长效果较好的冬片鱼苗。Proper neutron dose can stimulate fries to grow. The optimum neutron fluence is from9.2×10￣5cm￣(-2)to 18×10￣5 cm￣(-2).The yield of fries is increased by 16%─24%(silver carp fries) and 6%─30%(carp fries). The cultivated period of the treated silver carp fries is shortened by 28─45 days(1/3 to 1/2 period).The irradiated embryos of silver carp and carp are reared and produced for com-mercial adult fish in 1992.
