TOXICITY INDUCED BY CANA INDICA EXTRACTS ON FINGERLINGS OF CLARIAS GARIEPINUS
Abstract
This study aimed to assess the toxic potentials and histopathological changes in Clarias gariepinus fingerlings exposed to the ethanolic extract of Cana indica. Upon introduction of the extract to the test media, significant variations were observed in the water quality parameters, following a concentration-dependent pattern. Behavioural changes and modifications in the gill tissues were evident in the exposed groups, with severe alterations observed, excluding the control group. Mortalities were recorded in a concentration-dependent manner. The 96 hours LC50 for C. gariepinus for both batches (A and B) was given at 20.5 m/l representing a log transformed concentration of 1.31 mg/l. The results of the present study indicate a concentration-dependent pattern of mortality, with significant reduction observed over time of exposure. These findings underscore the potential toxicological impact of Cana indica extract on aquatic organisms, and pose high toxic effect on aquatic organisms. Therefore, there is need for further investigation into its environmental implications and management strategies.
