中文摘要：

鲍鱼 Haliotis diversicolor supertexta 是一个重要经济软体动物。解决和变形在它的发展时期期间是二个批评阶段，它在鲍鱼幸存和生产上有直接影响。鲍鱼胚胎和少年开发上的反应的氧种类(氢过氧化物) 的影响在这研究被检验。Haliotis diversicolor supertexta 的幼虫被导致到解决并且由暴露变形到与氢过氧化物补充的海水。他们在 800 μmol/L 有最好的表演。1 000 μmol/L 或更高的集中对幼虫有毒，当没有完全的变形，幼虫能仅仅在 benthic 硅藻盘子定居。另外， H ₂ O ₂ 增加时间对幼虫的表演批评。24h 在以后二天授精以后被证明是最佳的增加时间。在这篇论文，氢过氧化物的二行动机制被讨论：(1 ) 氢过氧化物有直接毒性到 ciliated 房间，因此引起 apoptosis；(2 ) 作为从 catecholamine 在 vivo 的自然氧化过程的一个产品，氢过氧化物能颠倒这个过程生产 neuro 传输器导致鲍鱼变形。

英文摘要：

Abalone Haliotis diversicolor supertexta is an important economic mollusk. The settlement and metamorphosis are two critical stages during its development period, which has direct influence on abalone survival and production. The influence of reactive oxygen species （hydrogen peroxide） on abalone embryo and juvenile development were examined in this study. Larvae of Haliotis diversicolor supertexta were induced to settlement and metamorphose by exposure to seawater supplemented with hydrogen peroxide. They had the best performance at 800 μmol/L. The concentration of 1 000 μmol/L or higher was toxic to the larvae, as the larvae could settle down only at benthic diatom plates without complete metamorphosis. In addition, H2O2 adding time was critical to the larval performance. 24h after two-day post-fertilization was proved to be the optimal adding time. In this paper, two action mechanisms of hydrogen peroxide are discussed： （1） hydrogen peroxide has direct toxicity to ciliated cells, thus cause apoptosis; （2） hydrogen peroxide, as a product from catecholamines＇ autoxidation process in vivo, can reverse this process to produce neuro-transmitters to induce abalone metamorphosis.
