本文报道了福建省水产研究所2005年黄鳍东方鲀人工育苗技术研究结果。在水温18.6~20.2℃、盐度27.3~28.6条件下,亲鱼催产效应时间为39~49h;在水温18~21℃、盐度27.3~28.6条件下,受精卵孵化时间为120~216h;在水温18~21℃、盐度20.0~30.0条件下,室内水泥池前期培育13d,仔鱼成活率69.7%;在水温26.0~29.0℃、盐度15.0~30.0条件下,30万尾稚鱼经池塘50d后期培育,共培育出平均全长3.9 cm、平均体重1.1g幼鱼5.0万尾,成活率16.7%。
This paper reports the results of the research on artificial seedling raising technology of the Yellowfin Oriental catfish in 2005 by Fujian Institute of Fisheries. Under the conditions of water temperature of 18.6-20.2 ℃ and salinity of 27.3-28.6, the time of brood stocking was 39-49h. Under the conditions of water temperature of 18-21 ℃ and salinity of 27.3-28.6, the hatching time of fertilized eggs was 120-216 hours. Under the condition of 18 ~ 21 ℃ and salinity 20.0 ~ 30.0, the indoor cement pool was cultivated for 13 days and the survival rate of larvae was 69.7% at the early stage of 50 days after the pond water temperature was 26.0 ~ 29.0 ℃ and the salinity was 15.0 ~ 30.0 Breeding, a total of average length of 3.9 cm, average body weight 1.1g larvae 50,000, the survival rate of 16.7%.
