Abstract

The aim of this study is to investigate the sensitivity of (Oncorhynchus mykiss, Walbaum, 1792), a salmonid fish species, to some toxic metal substances (Mercuric chloride; HgCl2, Zinc sulfate; ZnSO4, and Lead chloride; PbCl2) for aquatic ecosystems. The fishes were taken from local trout farms (Rize-Turkey) for bioassay experiments. The 96-h LC50 values for Rainbow trout were estimated, and their variations for each metal discussed. Lead chloride and zinc sulfate were less toxic for Rainbow trout as 20.21 mgL(-1) and 1.69 mgL(-1) respectively; however the most toxic metal was mercuric chloride (LC50: 0.81 mgL(-1)).
