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0.1~0.6 hm2,放养卵黄苗300~450万尾/hm2。试验结果表明:经25~30 d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。
從2012年至2014年,每年利用兩口池塘開展黃顙魚夏花苗種培育技術試驗,麵積0.1~0.6 hm2,放養卵黃苗300~450萬尾/hm2。試驗結果錶明:經25~30 d左右的培育,黃顙魚成活率33%~52%,平均規格900~1300尾/kg,餌料繫數0.50~0.80,培育池麵積小,黃顙魚放養密度低,則成活率較高,齣塘的規格較大,餌料繫數較低。
종2012년지2014년,매년이용량구지당개전황상어하화묘충배육기술시험,면적0.1~0.6 hm2,방양란황묘300~450만미/hm2。시험결과표명:경25~30 d좌우적배육,황상어성활솔33%~52%,평균규격900~1300미/kg,이료계수0.50~0.80,배육지면적소,황상어방양밀도저,칙성활솔교고,출당적규격교대,이료계수교저。
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 mil ion 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; smal cultivating ponds exhibited low stocking density of P. fulvidraco, resulting in high survival rate, large size and low feed conversion ratio.
