日本锦鲤秋季人工育苗及其离子轰击实验初报

Study on Artificial Prolmgation and Ion Bombardment of Japanese Koi in the Autumn

本文报道了2006年日本锦鲤秋季人工繁殖、育苗及其离子轰击日本锦鲤水花实验结果。8尾性成熟亲鱼,在14.5℃～23.2℃水温条件下,经强化培育后,采用地欧酮(DOM)、绒毛膜促性腺激素(HCG)催熟和催产,其中1尾雌鱼产卵。受精卵孵出水花1000尾。在15.2℃～21.0℃水温条件下,分离子轰击实验组、对照组和普通组共3组对日本锦鲤水花进行60d培育,成活率分别为66%、93%、51%;抽测普通组鱼苗,平均全长为2.4cm。

The artificial propagation, seeds breeding and lipper treated by ion bombardment of Japanese Koi were studied in Fujian Fisheries Research Institute in the autumn of 2006. 8 sexual maturation Japanese Kois were cultured at 14. 5 ℃ -23.2 ℃ water temperature, after the use of European one （DOM） and human eborionie gonadotropin （HCG） , one female fish spawned （ the yield was 2.5% ） and 1000 lippers were hatched. The ion bombardment experiment group, the ion bombardment control group and the general group were cultured 60d at 15.2 ℃ - 21.0 ℃ water temperature, and the survival rate were 66%, 93% and 51% separately. The average length of general group was 2. 4 cm.
