Abstract S968.31; 为了探究缢蛏(Sinonovacula constricta)在低盐水域养殖的可行性,从生存、摄食和生理代谢方面,比较分析不同驯化方式下缢蛏的淡化效果.设置3种不同低盐驯化方式的驯化组(Da组:盐度每48 h下降3的等速驯化组;Db组:盐度每24 h下降1.5的等速驯化组;Dc组:盐度大于10时每48 h下降3,盐度小于10时每24 h下降1的分段驯化组)和未驯化组(Ud组:盐度5),水体盐度从20淡化至5,驯化周期为10 d;检测了各实验组缢蛏的存活率、耗氧率、氨氮排泄率、摄食率及抗氧化酶活性.结果表明:各驯化组缢蛏的存活率均显著高于Ud组(43％),且De组成活率(86％)最高;Dc组缢蛏耗氧率、氨氮排泄率均显著低于Da组和Db组;Dc组摄食率显著高于Da组和Db组;Dc组缢蛏超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性波动最小.由此可见,采用较低淡化速率的分段式淡化模式优势显著,该结果为低盐水域开展缢蛏淡化养殖提供了参考依据.
