| 摘要: |
| 采用连续观察法研究翘嘴红鮊(Culter alburnus Basilewsky)人工授精的去膜受精卵的发育。结果显示,翘嘴红鮊胚胎发育可分为受精卵、胚盘形成、卵裂期、囊胚期、原肠期、神经胚期、胚孔封闭期、眼基和眼囊出现期、尾芽至肌肉效应期、心脏原基期至心脏博动期、出膜前期共11个时期。受精卵呈灰黄或青灰色,直径0.8mm左右,吸水后直径可达1.2mm左右,在水温27℃条件下,受精卵历时1560min孵化,积温702℃·h;初孵仔鱼全长2.3mm左右。 |

| Abstract: |
| A successive observation was conducted to study the embryonic development of Culter alburnus Basilewsky using artificially fertilized eggs whose membranes were dissolved.Embryonic development of C.alburnus was divided into 11 stages,such as fertilized egg,embryonic disc stage,cleavage stage,blastula stage,gastrula stage,neurula stage,closure of blastopore stage,appearance of optic rudiment and capsule stage,the stage from appearance of tail-bud to muscular effect stage,the stage from appearance of heart primordium to heartbeating and early hatching stage.Newly fertilized eggs were isabelline or caesious.The average diameter of the newly-fertilized eggs was about 0.8mm,and 1.2mm after absorbing water.At the water temperature of 27℃,the larvae hatched out at about 26 hours after fertilization and the accumulative temperature was 702℃·h.The average diameter of the newly hatched larvae was 2.3mm or so. |
