福建纹胸的成熟卵呈圆形 ,浅绿色 ,卵径 1.3～ 1.8mm。受精卵吸水后迅速膨胀 ,直径 3.0～ 3.6mm ,强粘性。膨胀后的次级卵膜上有一凹入的“漏斗”状结构与初级卵膜相连 ,不易分开。水温 19.0～ 2 6 .5℃时 ,胚胎发育历时 5 8h30min ;15 .6～ 18.5℃时 ,历时 115h5 0min。出膜仔鱼全长 4.4～ 5 .0mm。发育过程中胚胎位置状态的改变可以作为划分发育阶段的辅助标准。 Mature chestnuts of Fujian chestnut eggs were round, light green, egg diameter 1.3 ~ 1.8mm. Fertilized eggs rapidly inflated after swelling, diameter 3.0 ~ 3.6mm, strong viscosity. After the expansion of the secondary egg has a concave “funnel” structure connected with the primary egg membrane, not easy to separate. Water temperature 19.0 ~ 26.5 ℃, the embryonic development lasted 5 8h30min; 15.6 ~ 18.5 ℃, lasted 115h5 0min. Out of the film a full length of 4.4 ~ 5 .0 mm larvae. Changes in the state of the embryo’s position during development can serve as ancillary criteria for dividing the developmental stages.
