a 5m x 5m floating fishpen with a fine nylon net (for laguna lake or the rivers in bulacan) will require 20,000 pesos of input (fingerlings and feeds). in three months, you should be able to harvest 50,000 worth. yep, you need at least two 5 x 5 pens to earn a living. and the risks are high.
for a fish pond, the holding capacity is very small. a 3 x 5 x 1 pond (which you dug yourself) won't yield more than 5,000 pesos worth every three months.
yikes! one hectare? that's a project that requires a civil engineer and a fisheries expert. and there might be something wrong with my dimensions. 3x5x1 is just a backyard pond that can be used for home consumption (a father aided by his eldest son can't dig anything bigger). a commercial pond has to be bigger. also, a 1 hectare pond complex will probably need a deep well to keep your ponds charged. breeding above ground in a "dry" area can be expensive.
now, if you're the the mood to experiment, why don't you research on ionized oxygen filters? i watched this in a japanese embassy feature. with ionized oxygen, the water is very clean even though you stock it with twice the normal amount of fish ---and they reach harvest dimensions in less than half the time! my friend already researched it for commercial beeding of aquarium fish. he says the method is very expensive and requires a big scale of operations.
i think it's time you went to the bureau of fisheries.
