The genetic inactivation of eggs is the first key stage of androgenesis in fish. In order to observe the effect of UV irradiation for the inactivation of female nucleus of zebrafish the eggs were irradiated by UV with solution-free, pure water, Ringer's solution and Cortland solution. The results showed that abnormal fry were obtained in all groups and haploids were validated. But irradiation with solution was confirmed it could not inactive fully female nucleus and the fertilization rate of the eggs irradiated with pure water was very low.

雌核灭活是雄核发育的第一个关键步骤，为研究紫外线对斑马鱼卵的雌核灭活效果，将斑马鱼的卵采用干法或置于纯水、Ringer氏溶液和Cortland鱼用生理盐水进行紫外线照射，结果表明，各种方法中均得到畸形鱼苗，并经染色体检查大多为单倍体；四种方法中在Cortland鱼用生理盐水中灭活效果最好，120 mJ/cm2紫外线可以使雌核完全灭活；干法处理不能达到雌核完全灭活的目的，在纯水中灭活后的卵子受精率较低。

For about 3 weeks after free-swimming, they subsist on clusters of secretions (called "Discus milk") from the body as well as the dorsal fin of their parents.

孵化后3天的小鱼还挂在亲鱼所产的卵上，他们吸收着剩余卵黄，直至吃完，之后他们拥有足够的机能可以自由游动了，开始游近亲鱼并附在父母的表皮上。

Under light microscope, the egg is an oblated and agglutinated demersal with a narrow perivitelline space; eggs ranged in diameter from 1.95 to 2.38 mm with a mean of 2.18 ± 0.03 mm; their membrane are smooth and they have 5 to 7 cannular keratose egg-filaments; the oil globules are multiple, ranged in diameter from 0.05 to 0.50 mm and in number from 7 to 145 with a mean of 28±2, the position of them migrate during embryonic development; the yolks are ivory-white with no segments, ranged in diameter from 1.00 to 2.30 mm with a mean of 1.90 ± 0.03 mm; the development phases of the embryo are variable. So they were identified as the eggs of one Beloniformes.

在光学显微镜下：卵呈微扁圆形，卵径1.95~2.38mm，粘着沉性；卵黄间隙较窄，卵黄囊呈乳白色，无龟裂；卵膜平滑，在其表面有5~7根细长角质管状卵膜丝；多油球数不定（4~145），油球径0.05~0.50mm，油球在卵黄囊中的位置随不同的发育时期而不断发生变化；胚体处在不同的发育阶段，其特征符合颌针鱼目鱼卵的特征。

The results indicated: 1 .There is obvious difference between the gonads of precocious and unprecocious fish: in female, the ovaries of unprecocious fish stay in 141 stage, and are mainly consisted of oogonias and early oocytes; the ovaries of precocious fish have developed into IIIAV stage, most of the oocytes are in the large growth stage.

性早熟与未早熟大黄鱼性腺的发育有显著不同：未早熟鱼卵巢停留在Ⅰ～Ⅱ期，卵巢内主要由卵原细胞和早期卵母细胞所组成；性早熟大黄鱼卵巢已发育至Ⅲ～Ⅳ，卵巢内大多数卵母细胞处于大生长期中期或后期。
