本文研究了水产常规药物高锰酸钾、孔雀石绿、久效磷晶体敌百虫对虹鳟幼鱼的急性毒性。实验发现虹鳟幼鱼对高锰酸钾溶液24、48、96h的中间忍受限(TLM)分别为1.65、1.56和0.35mg/L,高锰酸钾对虹鳟幼鱼的安全浓度为0.035mg/L,虹鳟幼鱼对孔雀石绿溶液12、24、38、96h的中间忍受限分别为0.280、0.250、0.126、0.100mg/L。孔雀石绿对虹鳟幼鱼的安全浓度为0.010mg/L。虹鳟幼鱼对久效磷敌百虫中性溶液12、24、48、96h的中间忍受限分别为6.68、3.74、1.57、0.49mg/L,敌百虫对虹鳟幼鱼的安全浓度为0.049mg/L。
In this paper, acute toxicities of trichlorfon, a conventional aqua regia potassium cyanate, malachite green and monocrotophos crystal, to rainbow trout juveniles were studied. The results showed that the TLM of juvenile rainbow trout on the 24, 48 and 96h were 1.65, 1.56 and 0.35mg / L, respectively. The safe concentration of potassium permanganate on juvenile rainbow trout was 0.035mg / L , Juvenile rainbow trout on malachite green solution 12,24,38,96 h of the middle endurance limit were 0.280,0.250,0.126,0.100mg / L. Malachite green rainbow trout juvenile safety concentration of 0.010mg / L. Rainbow trout juvenile long-acting phosphorus trichlorfon neutral solution 12,24,48,96 h intermediate tolerance limits were 6.68,3.74,1.57,0.49mg / L, the safe concentration of trichlorfon juvenile rainbow trout was 0.049mg / L.
