Slight fluctuation in pH ranged between 7.2 to 8.1 with 7.7 mean value.
Dissolved oxygen shown highest mean values ranged between 6.9 to 11.5 rng/L in summer and winter respectively.
Variation values of gonado somatic index (GSI) recorded lowest ones in warmer months, whereas, the highest were in hot months.
