Effect of Water Velocity on Behavior,Antioxidant Enzyme and Residues of Enrofloxacin-HCl in Siberian Sturgeon(Acipenser baerii)
摘要
Abstract
The influence of water velocity (0,1.0 and 2.0 BL/s),on behavior,antioxidant enzyme and residues of enrofloxacin in Siberian Sturgeon Acipenser baerii[weight (82.1±4.9)g] was studied.The experiments were divided into 1 d,15 d and 30 d in three stages.On this basis experiments were conducted to study the res-idues and depletion of enrofloxacin-HCl of Acipenser baerii after different water velocity treatments ( 0,1.0 and 2.0 BL/s) .Muscle was sampled after oral administration at the dose of 50 mg/kg for seven consecutive days.It was found that the rheotaxis frequency ( RF) and the tail beat frequencies( TBF) showed a similar tendency:the RFand TBF of 1.0 BL/s and 2.0 BL/s groups were significantly higher than those of 0 BL/s group ( P<0.05) ,of which the maximum RF appeared in 1.0 BL/s in most periods of time and the maximum TBF was in 2.0 BL/s.The two indexes changed little with prolongation of time.It was also found that the MDA,CAT and SOD activities showed a similar tendency:increased with the increase in water velocity.The maximum antioxi-dant enzymes all appeared in 2.0 BL/s.The three indexes of 1 BL/s and 2 BL/s groups were significantly high-er than those of 0 BL/s group( P<0.05) .The three indexes remained stable with prolongation of time.In most time the residue levels of enrofloxacin-HCl of 1 BL/s and 2 BL/s groups were significantly lower than those of 0 BL/s.No medicine residues were detected in 8d under 2.0 BL/s,12 d under 1.0 BL/s while 20 d in the con-trol.The results showed that higher water velocity could induce rheotaxis behaviour,activate antioxidant enzyme and speed drug elimination.关键词
