摘要
研究了盐度（0．5、5、10、15、20、25、30和35）对凡纳滨对虾Litopenaeus vannamei（平均初始湿重0．776～0．781g）存活、生长和能量收支的影响。实验周期45d。结果表明，（1）对虾特定生长率、摄食量、饲料转换效率和吸收效率均以20盐度最高，而存活率以35盐度最高；（2）在0．5盐度下，对虾特定生长率、摄食量和吸收效率均最低。
The experiment was conducted to determine the effects of salinity （0.5, 5, 10, 15, 20, 25, 30 and 35 ） on survival, growth and energy budget of juvenile L. vannamei with the initial wet body weight of 0. 776 - 0. 781g. The experiment lasted 45 days. The results showed that I. The specific growth rate, food consumption, food efficiency and absorption efficiency were all at the highest values at 20, while the highest survival rate was at 35. Ⅱ. The lowest specific growth rate, food consumption and absorption efficiency were at 0.5.
