Population dynamics of important fishes in the Vindhyan region, India. Edition No. 1

VDM Publishing House, October 2010, Pages: 228

L8 was maximum in L. rohita and minimum in L. calbasu. Total mortality (Z) of L. rohita was higher in the Tons (4.19 yr-1) compared with the Ken (3.2 yr-1) and the Paisuni R. (3.67 yr-1). In case of T. tor higher mortality occurred in the Paisuni (5.57 yr-1) compared with Tons (4.28 yr-1) and Ken R. (4.08 yr-1). In case of L. calbasu it was same in the Paisuni (1.86 yr-1) and Tons (1.86 yr-1) and lower in the Ken R. (0.98 yr-1). The exploitation rate (E) and ratio (U) was higher in case of L. rohita in the Ken (0.77, 0.74) compared with the Paisuni (0.74, 0.72) and the Tons R. (0.56, 0.55). E and U for T. tor were higher in the Paisuni (0.82, 0.81) compared with Tons (0.80, 0.79) and Ken (0.71, 0.70). In case of L. calbasu also E and U were higher in the Paisuni (0.65, 0.55) compared with Tons (0.63, 0.53) and the Ken (0.52, 0.32). L. rohita was highly over exploited in the Ken and Paisuni R., T. tor in all these rivers and L. calbasu in the Paisuni and Tons R. being optimum in the Ken R. Among these three species E and U were higher for T. tor all in the rivers.
