Abstract:
The effect of cadmium (Cd) toxicity, its impact on histopathological changes, the median lethal concentration (LC50-96 h) and the bioremediation effect of Lemna gibba L and dried Spirulina platensis to grass carp, Ctenopharyngodon idella, were investigated through semi-static acute toxicity test developed with cadmium chloride (CdCl2). This study indicated that:1) Cd poisoning caused structural damage in the fish organs ,2) Lemna gibba L weed was effective in removing Cd from water and reducing its bioaccumulation in liver and muscular tissues of fish, 3) Addition of dried Spirulina platensis reduced significantly (P<0.05) the Cd level uptake as compared to fish exposed to Cd alone and 4) Addition of Lemna gibba L weed and dried Spirulina platensis were remediated the toxic effect of Cd and provided protection against the degenerative action of Cd in grass carp, Ctenopharyngodon idella. Spirulina platensis was effective in removing Hg from water and reducing Hg bioaccumulation in liver and muscular tissues of fish, as well as remediated the toxic effect of Hg and provided protection against the degenerative action of Hg in Nile tilapia, Oreochromis Niloticus.
