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.

The results showed that water content decreased first, then increased in the gastrula stage of embryonic development, reached the highest content at the second phrase larvae stage and then began to decrease from the third phase larva stage. The content of lipid in the dry weight increased with the embryonic development stages, but decreased at intramembranous nauplius stage, the second phase larva, and the infant stage of larvae development. The rate of lipid in wet weight decreased and the content of C20:4w6、20:5w3 and C22: 6w3 decreased.
结果显示,黑斑口虾蛄在胚胎和幼体的发育过程中,水的体积分数先降低,至原肠胚期开始升高,到第二相幼体期达到最高,之后又有所回落;脂类占组织干重的比率呈升高趋势,但分别在膜内无节幼体、第二相幼体和仔虾蛄期略有降低;脂类占组织湿重的比率呈降低趋势;花生四烯酸、EPA和DHA的体积分数都呈降低趋势。
