Abstract
The study evaluated the capital cost, operating cost and return cost and return of investment of varying level of greenhouse net shading capacity as top cover to 200 m² ponds. The economic profitability of 40, 60 and 80% greenhouse net shading capacity were analyzed for the reason that it affects the seed production of Nile tilapia during hot season (April to July). Some assumptions were introduced, since the data used in this study were generated from a research project so the data were not intended for a commercial production of aquashading. The estimated assumption for capital cost and operating costs calculated in each net shading capacity were all similar, the only variation for the total cost was the purchase price of greenhouse net. The total cost of production for each shading capacity in terms of yearly enterprise budget is presented. However, the calculated return of investment of aquashading for 40% and 60% net shading capacity will take more than eight production cycles which exceeded the duration of production (5 production cycles per year). The 80% net shading capacity attained to cover all the total cost for 3.01 production cycles. This net shading capacity also obtained the highest fry production so it makes it more economical than the other shading capacity in a commercial production setting.
