摘　　要：From 2012 to 2014, cultivation experiments of P. fulvidraco fries were carried out in two ponds every year, with the total area of 0.1-0.6 hm2 and stock- ing density of 3.0-4.5 million yolk-sac larvae. According to the results, after cultiva- tion for 25-30 d, the survival rate of P. fulvidraco was 33%-52%, the average size was 900-1300 individuals/kg, and the feed conversion ratio was 0.50-0.80; small cultivating ponds exhibited low stocking density of P. fulvidraco, resulting in high survival rate, large size and low feed conversion ratio.从2012年至2014年，每年利用两口池塘开展黄颡鱼夏花苗种培育技术试验。面积0．1～0．6hm2，放养卵黄苗300～450万尾／hm2。试验结果表明：经25～30d左右的培育，黄颡鱼成活率33％～52％，平均规格900～1300尾／kg，饵料系数0．50～0．80，培育池面积小，黄颡鱼放养密度低，则成活率较高，出塘的规格较大，饵料系数较低。
