研究发现,脊尾白虾的抱卵亲体和幼体对温度和盐度的适应性较强,在温度18￣24℃,盐度12￣28‰下均能进行正常的早期胚胎和幼体的发育,脊尾白虾的胚胎发育从囊胚期到孵化出共经5期,幼体发育共经6期发育成仔虾;在实验范围内,亲体孵化时数、孵化率、幼体发育时数和幼体存活率与温度成正相关,与盐度成负相关。另外,实验中亦发现其绝对抱卵量与体长、体重均呈正相关,其直线方程分别为Y=1,243.665L-3,420.67,(r=0.9357);Y=683.4872W-171.004,(r=0.9660)。
The results showed that the broodstock had higher temperature and salinity adaptability, and the development of normal early embryos and larvae could be carried out under the temperature of 18-24 ℃ and the salinity of 12-28% Shrimp embryo development from the blastocyst to hatch out through a total of 5, larvae develop a total of 6 larvae development; within the experimental range, the number of broodstock hatching, hatching rate, larval development and larvae survival rate and temperature A positive correlation, and a negative correlation with salinity. In addition, the experiment also found that the absolute amount of eggs and body length and body weight were positively correlated, the linear equation were Y = 1,243.665L-3,420.67, (r = 0.9357); Y = 683.4872W-171.004, (r = 0.9660).
