Abstract :
Population Dynamics of Macrobrachium malcolmsonii in Wyra, a tropical reservoir in India was studied. The growth parameters, mortality rates exploitation rates and maximum sustainable yield and corresponding fishing mortalities were evaluated. The von Bertalanffy parameters of growth are estimated as L∞ = 20.3 cm and K = 0.63 per yr. The instantaneous rate of mortality during the period is estimated at Z =2.23. Length at first capture is 4.0 cm. The maximum sustainable yield MSY is obtained at an E value of 0.48 and present E is only 0.33. Hence there is scope for further expansion of the fishery for M. malcolmsonii at the Wyra reservoir.
