摘要 在水温为11—15℃条件下,研究了不同浓度土霉素对虾夷扇贝Patinopecten yessoensis受精卵孵化率、幼虫成活率、相对生长率、眼点出现率及变态率的影响。结果表明:4mg/L以下浓度的土霉素对虾夷扇贝受精卵的孵化率没有明显负面影响;8mg/L以下浓度的土霉素对幼虫相对生长率、成活率和变态率无明显负面影响;1—8mg/L浓度的土霉素,对刚选育出的初期面盘幼虫壳长以及浮游和变态阶段幼虫的相对生长率、成活率和变态率有促进作用。 The effects of different concentrations of oxtetracycline on hatching rate, and larval survival, growth, eyespot occurrence frequency, and metamorphosis were studied in yesso scallop Patinopecten yessoeruis in a laboratory at a water temperature of 11 - 15 ℃. The results showed that the larvae had a very strong tolerance to the oxtetracycline. There was no significant influence on the hatching rate at a dose of 〈 4 mg/L oxtetracyeline. At a dose of 8 mg/L oxytetracycline, no significant negative effect on the larval growth, survival rate and the metamorphosis rate was observed. With the increase in the oxytetracycline concentration, the growth, survival rate and the metamorphosis rate tended to incrcase below 8 mg/L of oxytetracycline.
