摘要
在斑节对虾无节幼体下池前 2～ 3小时用 0 .0 15～ 0 .0 2 0 mg/L浓度的亚甲基蓝或三氟乐灵作预防 ,1～ 2天后发现有链壶菌感染时再用 0 .0 2 0 mg/L浓度的亚甲基蓝或 0 .0 2 0～ 0 .0 30mg/L 浓度的三氟乐灵治疗。两种药物比较 ,三氟乐灵能有效防治链壶菌病 ,其有效浓度为0 .0 2 0～ 0 .0 50 mg/L;而亚甲基蓝在链壶菌感染不严重时才有效 ,若感染严重或无节幼体下池前未施药预防 ,待发病后再用药 ,治疗无效。
Experiment on the control of Lagenidium disease in larvae of Penaeus monodon was conducted in this paper. To prevent the disease, 0.015 ～ 0.020 mg/L methylene blue or trifluralin was used 2～3 hours prior to the larvaes stocking ; to cure the disease, 0.020 mg/L methylene boue or 0.020 ～ 0.030 mg/L trifluralin was used after their stocking. Results of this experiment suggest that trifluralin can control the Lagenidium disease effectively, and the effective concentration is 0.020 ～ 0.050 mg/L; while methylene blue is effective only when the disease is not serious. If the disease is serious or there is no prevention before the larvaes stocking , methylene blue will have no effect.
