As it has been seen, all levels of intensification in freshwater aquaculture are developed around the world: from the most extensive to the most intensive. Two examples are presented here.
In the Philippines, the annual budgets of several fish farming systems are given: rice-fish culture, fish-pig integrated farming, and floating cage fish culture (Tables 15–17).
Table 15.
Simple annual cost and return for a 1.000 square meter rice-fish culture project (two croppings) in the Philippines as of 1990 (in P, 1 US$ # 30 P).
Table 16.
Semi-annual budget for a 1.000 square meter excavated earthen fishpond integrated with a head pig fattening, as of 1990 (in P, 1 US$ # 30 P).
Table 17.
Annual budget for a tilapia cage culture farm in the Philippines. Economic analysis shows higher profitability for integrated systems. A comparative analysis of rates of return of various systems shows that integrated livestock-fish systems are the most profitable with rate of return on investment higher than 63%.
