Hepatosomatic and Renosomatic Indices of &i&Anabas testudineus&/i& Exposed to Various Levels of Cadmium

摘要

Cadmium has a high level of toxicity and can have adverse health effects on living organisms including fish. This study is conducted to identify the effects of cadmium exposure on the Hepatosomatic Index (HSI) and Renosomatic Index (RSI) of Anabas testudineus . Anabas testudineus is exposed to four different cadmium treatment groups. The fishes were exposed to four treatment groups of different cadmium concentrations (0.000 mg/L, 0.005 mg/L, 0.010 mg/L and 0.015 mg/L) for 16 weeks. The results showed a decreasing trend of HSI value increasing cadmium concentration and exposure time. However, the opposite trend was observed with RSI where the higher the cadmium concentration over an increased exposure time, the higher the RSI. In conclusion, the study outcome shows significant changes in the value of HSI and RSI between different treatment groups with exposure time.
