Do you have a space in your backyard of 2 or 3 square meters, regardless of shape, you can start producing your own Tilapia Fish and vegetables. Ideally, the fish feeds the plant and the plant feeds the fish, totally organic, no chemicals, no pesticides, no fertilizers, once you get the system in the right balance. System is modular and expandable and if you have a fence, you can start growing your vegetables vertically. No water is wasted and ideal for handicaps (except blind) as they can do some simple maitenance work and watch the fish and plant grow. US technologies - standards can produce as much as 150 to 200 or even more fishes per sq.m., Philippine Pond standard can only produce 5 fishes per sq. m. hence you need hectares to produce what 10 or 20 sq. meters backyard can do. This is one of the possible backyard - hobby activity that you can learn small scale and turn into big scale commercial, after all the big always come from the small, if they can make this happen in the US, no reason why we cannot do it in Cebu.
