泥鳅人工繁殖、鳅苗培育及碳铵安全浓度试验

Artificial multiplication of loach,cultivated loach fry and safe concentration test for ammonium bicarbonate

利用蛙垂体、鲤鱼垂体、ＨＣＧ、ＬＲＨ－Ａ对泥鳅催产效果的比较，得出鲤鱼垂体＋ＬＲＨ－Ａ作用效果最好，ＨＣＧ＋蛙垂体＋ＬＲＨ－Ａ次之，蛙垂体＋ＬＲＨ－Ａ最差；用不同饵料喂养鳅苗的结果是：用豆浆作鳅苗饵料要比奶粉、轮虫、蛋黄有较好的效果；在稻田中碳铵对泥鳅的安全浓度以２３１．８ｍｇ／ｋｇ为好。

The present paper give a description of comparison effect of the loaches′re-production by different medical herbs. The results show that the multiplying effect order iscarp fish PG first,then HCG+frog PG+LRHA,and finally frog pG+LRH-A.The re-sults of loaches feed on different food show that beancurd milk is better than milk , powder,rotifora and yolk. The safe concentration of ammonium bicarbonate in rice fields to loach is231.8mg/kg.
