Özet:

 

The stressed ecosystem and the accumulation of inorganic pollutants in Kuwait Bay instigated us to conduct toxicity and bioaccumulation tests on trace metals (Zn, Cu, Cd and Fe) to mudskipper, Periophthalmus waltoni, a bio-indicator fish to marine pollution. Among the four metals, Cd had the lowest observed effective concentration (LOEC) at 1.5µg L-1. Probit analysis showed toxicity tests (96 h) on P. waltoni reared in filtered seawater in the laboratory showed Cd with maximum effect at median lethal concentration (LC50) followed by Fe, Cu and Zn. Bioaccumulation factor (BAF) was in the sequence of Cd > Fe > Cu > Zn. For fish exposed for 60 d, bioaccumulation exhibited increasing metals levels in liver followed by muscle tissues and gills. These results will support ecologists to use P. waltoni as a bio indicator to metal pollution in the future.  	 	 		 .
