The condition index of two abundant gastropod species of Turbo (T. coronatus and T. intercostalis) from exploited and non-exploited sites of Karachi was studied on monthly basis, for a period of one year from October 2004 to September 2005. A significant difference in condition index of two species from exploited and non-exploited sites was demonstrated. Condition index values were relatively higher and less varied throughout the year in both the species of Turbo at less polluted and non-exploited site (Nathiagali) as compared to polluted and exploited site (Buleji). The two sites also differed in the period of highest and lowest condition index values of standard size snails of both species of Turbo. An inverse relationship between condition index and shell height of snails was noted for most of the year in both the species. The results are discussed with reference to their presence under different environmental conditions.
