研究了中国对虾 (P chinensis)成活率及生长率与盐度变化关系 .盐度偏高 (大于35‰ )时 ,对中国对虾生长不利 ,致使其生长缓慢 ,甚至死亡 .而盐偏低于 15‰时 ,可加速蜕皮 ,对其生长有促进作用 .但盐度突变会导致大批死亡 .结果表明 ,其适宜盐度为 15‰～30‰ .在此范围内 ,虾存活率和生长率较高 . The relationship between the survival rate and the growth rate of P. chinensis and the change of salinity was studied.The salinity was higher than 35 ‰, which was unfavorable to the growth of Penaeus chinensis, resulting in the slow growth and even death.While the salinity was below 15 ‰, it can accelerate the molting and promote its growth, but the salinity mutation will lead to a large number of deaths.The results showed that the suitable salinity was 15 ‰ ~ 30 ‰ .In this range, the survival rate and growth rate of shrimp is higher .
