采用双层塑料袋向许家崖水库移植大银鱼受精卵３０万粒，放卵后用木制孵化箱进行孵化，孵化率６７％。大银鱼产卵时间可从１１月中旬持续到翌年１月底，高峰期为１２月２８日至翌年１月４日，平均怀卵量８０００粒，雌雄比３：５。选择成熟亲鱼，进行人工采卵授精，受精率为７５％。专家鉴定认为，本研究成果居国内领先水平。在大银鱼人工繁殖方面，对亲鱼成熟度的鉴别、亲鱼选择、人工授精技术、受精卵的贮存、运输技术等都有创新点。
The double-layer plastic bag was used to transplant 300,000 large-sized silverfish fertilized eggs to Xujiaya Reservoir. After hatching, the eggs were incubated in a wooden hatchery with a hatching rate of 67%. Silver sparrow oviposition time from mid-November until the end of January the following year, the peak from December 28 to January 4 the following year, with an average of 8,000 eggs and ovulation ratio of 3: 5. Select mature broodstock, artificial egg fertilization, fertilization rate of 75%. Experts believe that the research results in the leading domestic level. In the artificial breeding of big whitebait, the identification of broodstock maturity, selection of broodstock, artificial insemination technology, storage and transportation of fertilized eggs, etc. have innovative points.
