摘要
葡萄牙牡蛎眼点幼虫暴露于K+、Ca2+、Mg2+、NH4+不同添加浓度的海水溶液中。结果显示:在最初4 h内K+和NH4+可明显诱导幼虫的附着行为;7 d后,10 mM和20 mM的K+以及10～25 mM的Ca2+可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+、Ca2+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。
Portuguese oyster larvae were exposed to solutions of K^ ＋ , Ca^2＋ , Mg^2＋ and NH4 at various con- centrations. The result was showed below： At the beginning of the test, K^ ＋ and NH4 induced larvae settlement behavior. After a week, except Mg^2＋ and NH4 , under the concentration of 10 mM, 20 mM, K^＋ and 10 mM -25 mM, Ca^2＋ both induced larvae settlement and metamorphosis; NH4 caused high mortality. This indicated that in commercial breeding of Portuguese oyster, K ^＋ and Ca^2＋ might be the potential chemical cues.
