长薄鳅胚胎发育的观察

OBSERVATIONS ON THE EMBRYONIC DEVELOPMENT OF LEPTOBOTIA ELONGATA

    摘要
  • 摘要: 1999年5月,作者首次通过人工繁殖获得长薄鳅的受精卵,并对其胚胎发育特征进行了连续的观察。卵膜无粘性,吸水后卵周间隙明显膨胀扩大,卵膜径3.67-4.00 mm,平均3.79mm,属漂流性卵。胚胎发育可分为26个时期,初孵仔鱼长5.0mm左右,通体透明无色素。

     

    Abstract: From May to June 1999, the embryonic development of Leptobotia elongata was observed with artificial fertilized eggs.The egg membrane is non-adhesive and expands after absorption of water, and its diameter ranges from 3.67 to 4.00mm, averaging 3.79mm.The eggs drift in flowing water.The process of embryonic development can be divided into 26 stages.Newly hatched larvae were 5.0 mm in total length and non-pigmented.
