中文摘要 | 1.氨對於臺灣馬口魚的24-h,48-h,72-h及96-h之半致死濃度(LC�t)分別是 5.82,5.33,5.04 及 5.00 mg ╱ l NH �� -N。 2. 亞硝酸對於臺灣馬口魚的 24-h,48-h, 72-h 及 96-h 之半致死濃度( LC �t)分別是 141.10, 84.38,73.83 及 40.16 mg ╱ l NO �� -N。 3. 氨對臺灣馬口魚魚苗的毒性比亞硝酸者為強。 4. 對於臺灣馬口魚的魚苗培育, 比較保守的 " 生物安全濃度 ", 氨是 0.50 mg ╱ l NH �� -N,亞硝酸是 4.02 mg ╱ l NO �� -N。 |
英文摘要 | Acute toxicity of ammonia and nitrite to juvenile freshwater fish Zacco barbata was studied, in order to set up water quality requirements for farming and protecting this fish. 1.The 24-h, 48-h, 72-h, 96-h LC �t (median lethal concentration) of ammonia for juvenile Zacco barbata were 5.82, 5.33, 5.04, 5.00 mg/l NH �� -N, respectively. 2.The 24-h, 48-h, 72-h, 96-h LC �t (median lethal concentration) of nitrite for juvenile Zacco barbata were 141.10, 84.38, 73.83, 40.16 mg/l NO �� -N, respectively. 3.Biological safe concentration for juvenile Zacco barbata was 0.50 mg/l NH �� -N and 4.02 mg/l NO �� -N, respectively. 4.It is clear that ammonia shows more toxic to juvenile fish than nitrite. |
