Additionally, multiple regressions between FCR as dependent variable and ABW and ADG as independentvariables substantiate that the lower stocking density (15 mG ) of P. monodonprovides highest ABW,ADG, AFG and survival in T1 ponds compared to the others. Finally highest return on investment of 67%in T1 than others (T2=56.3% and T3= 22.2%) suggests that the low density of 15 mG is the optimum to ascertain cost efficient and sustainable production of P. monodonin a semi-intensive farming system
