Aquaponics is an acronym for Hydroponic Aquaculture demand using an integration system between aquaculture activities and hydroponic planting in rearing containers (tanks/ponds). In simple language, it means farming fish in a tank with vegetables where the final production will be fish and vegetables. Farmed fish are not from the type that consume vegetables, but instead they are non-eating vegetables small fish (ornamental fish) such as guppy, platy, molly etc.The edible fish that are suitable to be farmed are Gourami, Climbing Perch, Snakehead and Catfish. While, suitable type of vegetable is water spinach, green leafy vegetable floated on the surface of the tank using cork or polystyrene. The plants in this system will absorb nutrients from the water produced from fish feces and food waste. (Plants as biological filters)Having the absorption of nutrients by plants will make the water become clearer, improved water quality and the ecosystem in the tank will be more balanced where fish can live healthily and grow. Plants placed in the rearing tank must not exceed 1/3 of the surface area of ​​the tank so that sunlight can penetrate to the base of the tank and will encourage the growth of plankton as a natural food for the farmed fish.If you have any question, please contact Marine Aquaculture Branch, Fisheries Headquater Putrajaya Tel : 03-8870 4784.
