Abstract: | Fingerlings of Channa punctatus, a freshwater murrel, when subjected to a sublethal concentration of 12 mg l?1 zinc for 20 days elicited a significantly decreased (P<0.01) RNA content and hypoproteinemia in their liver. However, an exposure for 10 days under the same condition did not produce a significant alternation (P>0.05) neither in the nucleic acids (RNA – DNA) nor in the protein content. Results are discussed in relation to the pollutional stress of this heavy metal. |
