摘要: 葡萄牙牡蛎眼点幼虫暴露于K+、CaCl2、MgCl2、NH4Cl不同添加浓度的海水溶液中。结果显示:在最初4h内K+和NH4+可明显诱导幼虫的附着行为;7d后,10mM和20mM的K+以及10~25mM的Ca2+显著诱导幼虫的附着变态,Mg2+与对照组相比无效,NH4+造成幼虫高死亡率。这表明K+、CaCl2可能成为葡萄牙牡蛎育苗生产上幼虫附着变态的有效诱导剂。

Abstract: Portuguese oyster larvae were exposed to solutions of KCl、CaCl2、MgCl2、NH4Cl at various concentrations. The result is showed below. At the beginning of the test, K+ and NH4+ induced larvae settlement behavior. After a week, except Mg2+ and NH4+, under the concentration of 10mM,20mM, K+ and 10mM-25mM, Ca2+ both induced larvae settlement and metamorphosis; NH4+ caused high mortality. This indicated that in commercial breeding of Portuguese oyster, KCl、CaCl2 may be the potential chemical cues.
