【摘要】 本文报道了菊黄东方鲀胚胎及仔稚幼鱼发育情况.其结果表明:在水温20-21℃、盐度20-30、pH值8.0-8.3的条件下,受精卵受精后2h为2细胞期、15h为囊胚期、30h为原肠期、55h为胚体期、152h孵出仔鱼;孵出仔鱼在水温19-28℃、盐度20-30、pH8.0-8.3条件下,孵化后5d开口、18d进入稚鱼期、40d进入幼鱼期.此外,对胚胎及仔稚幼鱼各发育阶段进行较详细描述、测量并给出示意图.更多还原

【Abstract】 This paper reported the embryonic and larval development of Fugu flavidus.It showed that in conditions of water temperature 20～21℃,salinity 20～30,pH 8.0～8.3,the fertilized eggs developed to 2-cell in about 2h,blastula stage in about 15h,gastrula stage 30h and the hatched out larva 152h after fertilization.And in conditions of water temperature 19～28℃,salinity 20～27,pH 8.0～8.3,the larva opened its mouth at the 5th day.It became juvenile at the 18th day and young fish at the 40th day after hatching.更多还原
