Özet:

 

The  spotted murrel, Channa punctatus were exposed  to  sublethal concentration of endosulfan  (8.1 µg/L)  for 48 and 96 h  to  elucidate the impact of the pesticide on the ionic composition in different organs of the fish. After 48 and 96 h endosulfan exposure,  fish were randomly selected  from each control and experimental  tanks, anesthetized, sacrificed and  then different organs  like  liver,  kidney,  gill  and muscle were  dissected  for mineral  estimation. Results  showed  that  liver Ca  and Mg  levels  after  48  h  increased  significantly, however after 96 h, these two minerals showed reduction in their levels. The remaining minerals in the liver (P, Na, K,  Fe, Zn, Cu and Mn) did not change significantly with increase in the exposure duration however, showed a decreasing trend after 96  h. Kidney Ca and Mg after 48 h exposure  increased significantly by 89.5 and 79.8% and after 96 h  the concentration of both  these  minerals were non-significantly higher by 23.2 and 27.8% from  the control. Kidney Mn  level after 96 h was also significant higher  (by 31.7%) than the control. The remaining kidney minerals (P, Na, K, Fe, Zn and Cu) did not change significantly with change in the  exposure duration, however, after 96 h some of them (P, Na, Zn) increased. Gill Ca level decreased significantly with the increase in  the duration of endosulfan. Gill Fe and Cu levels also showed almost similar trend like gill Ca. The remaining minerals (P, Na, K, Zn,  Mg and Mn) in the gill were not significant influenced by endosulfan exposure however, they (except Mn) showed a decreasing trend  after 96 h. In muscle tissue, P and K increased significantly with the increase in the exposure periods whereas, muscle Zn showed a  reverse trend. The remaining minerals (Na, Ca, Fe, Mg, Cu and Mn) did not change significantly with the change in the endosulfan  exposure time however, they (except Mg and Mn) showed a decreasing trend at the end of 96 h. In essence, the present study showed  that  the concentration of majority of  the minerals  in  the  liver, gill and muscle after 96 h endosulfan exposure decreased, however,  their level increased in the kidney. Thus, exposure of sublethal endosulfan concentration to C. punctatus caused significant alterations  in the ionic composition in different organs of their body. 	 	 		 .
