| 摘 要： | 以不同浓度的氯化钾(KCl)溶液处理仿刺参(Apostichopus japonicus)樽形幼虫,处理不同时间后,分析KCl对仿刺参幼虫附着变态的诱导作用。结果表明,使用较低浓度的KCl溶液(10、30和50 mmol/L)分别诱导仿刺参樽形幼虫6、12和24 h均可以显著提高其附着变态率,诱导24 h附着变态率分别提高27.67%、32.67%和19.67%。较高浓度的KCl溶液(100、300和500 mmol/L)也可以诱导仿刺参幼虫附着变态,但随着KCl浓度的升高和诱导时间的延长,幼虫死亡率逐渐升高。低浓度KCl溶液,特别是在30 mmol/L诱导仿刺参幼虫12 h时,可以显著提高幼虫的附着变态率,增加发育的同步性,降低死亡率,对仿刺参幼虫变态的诱导效果较好。

| Abstract: | The impact of potassium chloride (KCl) solutions on settlement and metamorphosis of doliolaria larvae of sea cucumber (Apostichopus japonicus) was studied in present work. Exposure of KCl was set in a spectrum of concentration at 10, 30 and 50 mmol/L for 6, 12, and 24 h. The results showed that the metamorphosis rates were significantly increased in KCl exposure at 10, 30, and 50 mmol/L for 6, 12, and 24 h; for example in 24-h group, it increased by 27.67%, 32.67%, and 19.67%, respectively. Although higher concentrations (100, 300, and 500 mmol/L) could also induce the metamorphosis, the mortality rate might rise with increasing KCl concentration and induction time. Overall, 12 h induction in low concentrations of KCl solution, e.g., 30 mmol/L, could significantly enhance the metamorphosis rates. Therefore, the combination of KCl treatment for doliolaria larvae in 30 mmol/L for 12 h was recommended in favor of the synchronism development in less mortality rate for better induction effect. |
