摘　　要：本文为了比较不同水处理方式对方斑东风螺幼体生长发育的影响,选择同一批卵囊孵化的幼体,采用多肽菌素、芽孢杆菌、噬菌肽和溶菌酶、二氯海因等试剂处理育苗过程中的海水,检测处理后海水中弧菌和总细菌含量,并测定方斑东风螺幼体的生长率和变态率等指标。结果显示,处理过的育苗海水中细菌和弧菌含量均有不同程度的下降,幼体的生长速度较对照组显著提高。用多肽菌素处理后,育苗用水中的弧菌量最低,幼体生长速度最快,变态率最高,表明多肽菌素可有效提高方斑东风螺苗种成活率。本研究可为方斑东风螺人工育苗过程中合理选择水处理制剂和方式提供参考。To compare the effects of different water treatment methods on the growth and metamorphosis of Babylonia areolata larvae, the larvae hatched from same batch of zygotes were cultured in seawater treated with polypeptide S100, bacillus, phage and lysozyme, and dichlorohydantoin, respectively. The content of vibrio and total bacteria in seawater was detected. The growth rate and metamor-phosis rate of the larvae were measured. The results showed that the content of total bacteria and vibrio in the treated seawater was decreased, and the growth rates of larvae were higher than that of the control group. The larvae cultured in seawater treated with polypeptide S100 showed the lowest vibrio content, the fastest growth and maximum metamorphosis rate, indicating polypeptide S100 can effectively improve the survival rate of the larvae. This study can provide a reference for the rational selection of water treatment agents and methods in the artificial breeding of B. areola-ta.
