These are some of the main components to rear the fish and plants. These are used to help the process along. Without these main components the process would not work very well. I am studying the parts of the process so I am able to include them into the mural. The different parts of the process to resemble the aquaponic process which will be the main components for the mural I create.
Some of these components consists of:
- Rearing Tank: This is the tank used for raising and feeding aquatic animals such as fishes. It doesn’t have to be a traditional fish tank, instead, barrels and other forms of containers can be used.
- Solids Remover: This is the component responsible for catching uneaten feed and detached biofilms, and also for settling out fine particulates.
- Biofilter: This section is in place for bacteria to grow and convert ammonia into nitrates for plants to absorb.
- Hydroponics Subsystem / Grow Bed: Plants are grown here to take in all the excess nutrients from the water.
- Water Pump: This is the lowest part of the system where water flows to and then pumped back into the rearing tank.
- Water: The water in an aquaponics system is recirculated and reused in an effective way. The working relationship between the aquatic animals and the plants allows for a stable environment for both to survive. Water is only added when there’s water loss as a result of absorption and transpiration from plants, evaporation or overflow from rainfall.
- Feed: As a result of depleting wild fish stock, fish meals from lower value species is not sustainable. Therefore, organic fish feeds is a viable alternative. Others include duckweed, worms and black soldier fly larvae.
- Electricity: The amount of energy used all depends on the size of the aquaponics system and whether it’s indoors (requiring the need for grow lights) or outdoors. It can be highly energy efficient if the system uses alternative energy and less pumps by allowing the water to flow downwards.
