The development of technology makes it easier for someone to do different things from time to time, one of which is related to aquaculture or plants. Especially if you have land that is not too wide. Aquaponics is a solution for someone who wants to fish or grow crops but has a limited land area. In this article, we will talk in detail about the aquaponic system in aquaculture.
Before proceeding, do you know what aquaponics is? Aquaponics is a combination of several methods of aquaculture and plants in one very efficient place. Fish farming is the main business, vegetable growing is secondary or additional. So this aquaponics uses a combination of plant fisheries that are later used together. Fish are an important component in aquaculture systems as fish provide almost all of the nutrients for plants derived from manure or feed residues. There are different species of fish that can be cultured in this aquaponic system including catfish, goldfish, and catfish. Plants suitable for aquaponics include kale, lettuce, and tomatoes.
What is the concept of aquaponic farming?
The aquaponics system combines closed-loop fish farming with hydroponic crop or vegetable production, where recycling takes place so that the waste from fish farming is an input/source for the vegetable farming system.
The purpose of the circulation system can be described as that the water from the fish rearing tank is sent by a water pump to the filter, which also serves as a planting place, and then the filtered water is returned to the fish pond, it is continuously flowed, so that the ammonia in the pond up 80% of the plants that followed, such as B. tomato chili plants, is filtered. The filter medium does not use soil in its implementation, for the plants to grow well, they must first be sown until the seedlings are 1-1.5 months old and ready to be transferred to the aquaponic system at a certain distance.
Things to consider when starting an aquaponic system are the selection of plant materials and fish species to use. Some plants can be cultivated with aquaponics, namely lettuce, chili, tomato, kale, eggplant, melon, cucumber, and so on. Meanwhile, the types of fish that are suitable for combining with plants in the aquaponic system are catfish, goldfish, tilapia, koi, mujair, and so on. Usually, this catfish is widely distributed as it can produce a lot of ammonia as a nutrient for plants and can survive in relatively dirty water. In addition, catfish also have a high metabolism. Well suited as a carbon, nitrogen, and phosphate source for plant nutrition.
When choosing plant raw materials, you need to make sure that the type of plant you choose matches the height of the planting medium and the type of tidal system. For example, if the height of the planting medium is 5-10 cm, short-stemmed plants can be planted, such as lettuce, mustard greens, kale, and celery. However, if the height of the planting medium is around 20-30 cm, you can plant plants such as chilies or tomatoes.
Then you should choose a leaf for the growing medium itself that has not decomposed, does not change the chemical composition of the water, and is free of compounds that are poisonous to plants.
Implementing an aquaponics system can save you land. If traditional farming and ranching farm are two fields, this system means you only need one land to farm both. The plant-based products you make also fall into the organic category. This is because plants get nutrients from fish droppings without the need to add industrially manufactured fertilizers.
Some of aquaponic growing system
Aquaponics can be made on a small scale aimed at decorating the yard or on a large scale used for business or commercial purposes. There are different types or models of aquaponics that are commonly used by farmers and researchers. Below are the different species found in aquaponic growing systems including:
A raft system is a system where the plants are placed directly on top of the water so that the plant roots float in the water. Of course, the fish are placed in different ponds. because if not, the plant roots will be eaten by fish.
EBB flow system
The ebb and flow system works with a bell siphon. The bell siphon is designed to release water when the water has filled the growing medium.
NFT (Nutrient Film Technique) system.
This system works by directing a thin amount of water directly to the plant roots. This system relies only on circulating water that is continuously pumped into a reservoir.
Benefits of Aquaponic Growing System
Each technology must have its advantages and disadvantages, including aquaponics cultivation technology that has advantages in various ways such as B. the following.
The advantages of the aquaponic system include the use of water that is very efficient, more space efficient, more environmentally friendly as it does not pollute the environment, produces organic vegetable fish as it is free of pesticides, regardless of the season because it is indoors or outdoors can be applied outdoor (outdoor), Produce two products at the same time in one production, namely fish and vegetables.
Weaknesses of the aquaponic farming system
For example, although aquaponic cultivation has some advantages, it does not escape several weaknesses of this cultivation system: Requires a fairly high cost, then relies on electricity, since the water pump in aquaponic cultivation can be operated when the pump is powered by electricity. The latter requires special care.
