【摘要】 比较了不同盐度(5、10、15、20、25、30、35、40、45)及pH条件(5.0、5.5、6.0、6.5、7.0、7.5、8.0、8.5、9.0、9.5)下黄鳍东方鲀受精卵的培育周期、孵化周期和孵化率,同时对黄鳍东方鲀初孵仔鱼进行耐饥饿试验,测定其不投饵存活系数SAI值。结果表明,黄鳍东方鲀受精卵孵化的适宜盐度范围是5.0~40.0,适宜pH范围是6.0~8.5;仔鱼生存的适宜盐度为5.0~45.0,适宜pH值是5.5~9.0。更多还原

【Abstract】 The effects of difgerent salinity and pH values on the incubating period,hatching period,hatching rate of fertilized eggs of Takifugu xanthopterus,and the survival activity index(SAI) of newly hatched larvae were determined and compared,respectively.The results showed that: salinity from 5 to 40 and pH from 6.0 to 8.5 are suitable for hatching,while salinity from 5 to 45 and pH from 5.5 to 9.0 are suitable for larvae survival.更多还原
