A comprehensive farm-level stochastic and dynamic capital budgeting si
mulation model (AQUASIM) is used to evaluate the economic benefits of
incorporating a small-scale trout enterprise with a grain and broiler
farm. The simulation results indicate that combining aquaculture produ
ction with traditional agriculture increased expected income and reduc
ed risk substantially. The use of external debt capital improved the a
fter-tax net present values and internal rates of return but lowered n
et cash farm income. This study shows the importance of enterprise div
ersification in stabilizing variability in expected income.
