2006年5月15日和2008年5月12日分别自福建宁德和山东青岛购入条石鲷受精卵0.6 kg和1.4 kg,带回育苗场进行人工孵化,孵化水温19.5-22.1℃,密度1.018-1.022 kg/m~3。受精卵孵化率分别为64%和78%,经过35天左右的培育,仔稚鱼长度达到了3cm左右,育苗成活率分别为2.3%和3.82%。培育期间,由于饵料的原因致使出现死亡高峰,适口的饵料和营养水平是海水鱼类仔稚鱼培育的关键。
On May 15, 2006 and May 12, 2008, 0.6 kg and 1.4 kg fertilized eggs of Gyps myrobalan were purchased from Ningde, Fujian Province and Qingdao, Shandong Province, respectively. The fertilized eggs were returned to the nursery for artificial hatching. The incubation temperature was 19.5-22.1 ℃ and the density was 1.018 -1.022 kg / m ~ 3. The hatching rates of fertilized eggs were 64% and 78% respectively. After 35 days of incubation, the length of larvae reached 3 cm, and the survival rates of seedling were 2.3% and 3.82% respectively. During the incubation period, the peak of death occurs due to the feeding of bait, and palatability and nutrient level are the key points for the cultivation of marine fish larvae.
