Carbohydrate Reserves And Metal Accumulation Of The Nile Tilapia, Oreochromis Niloticus After Treatment With Heavy Metals

This study investigated the carbohydrate reserves and metal accumulation of the Nile tilapia, Oreochromis niloticus after exposure to sublethal concentrations of heavy metals such as copper, lead and zinc for a 12-week period, using static renewable toxicity tests. The concentrations of the metals accumulated in the tissue of exposed fish were about 3-5 times higher than the concentrations detected in control fish. The accumulation of plasma glucose in O. niloticus was observed to be dose dependent. It is significantly higher (P
