Just a small space measuring 1 meter x 2. 5 meters with plenty of sunlight is enough for you to raise your fish and grow your veggies too. This system for farming fish and plants together, called aquaponics, was featured in the recently held National Science and Technology Week (NSTW). The fish waste provides the nutrients for the plants, while the plants filter the water for the fish. A pump is used to circulate the water from the fish tank (blue container) into the series of tubes where the plants are contained and back into the fish tank. The setup shown is best suited for raising tilapia, and other freshwater fish, and growing leafy vegetables such as pechay, lettuce, and kangkong. NSTW is a yearly initiative of the Department of Science and Technology and was held from July 24-28, 2014 at the SMX Convention Center. (S&T Media Service)
