摘　　要：粘皮鲻鰕虎鱼(Mugilogobius myxodermus)的卵产出时为球型,直径0.40~0.60mm,具黏性,卵颜色淡黄,半透明,油球多且数量不固定。受精5~10min后吸水膨胀成椭圆形。水温16~18℃的条件下,胚胎发育共需138h。初孵仔鱼体长2.30~3.10mm,体高0.35~0.40mm,总肌节29~30。出膜30min^24h内鳔充气,从孵出到各鳍分化完全约需要40d。Based on our observations, the eggs of Mugilogobius myxodermus are round, sticky, translucent, light yellow in color, rich in oil globule, and 0.40 - 0.60 mm in diameter. At 5 - 10 min of fertilization, the eggs begin to absorb water and become ellipse. At 16 - 18℃, the embryonic development lasts 138 h. The larva is 2.30- 3.10 mm in length and 0.35 - 0.40 mm in height, with 29 - 30 myomeres. The inflation of the pneumatic cyst occurs from 30 min to 24 h after hatching, and all the fins are developed during the following 40 days.
