What can be grown in aquaponic?
The completed aquaponic system couples aquatic animals and plants in water. The number of plants and animals you can grow depends on the capacity of the system. Here are some recommendations on aquaponic plants and fishes.
Plants that have low nutrients needs and grow well in the new system should be considered first. They are green leaf, red leaf, mint, swiss chard, arugula, basil, watercress, and other leafy lettuces.
If you have already had experience in the aquaponic system, you can challenge yourself with some fruiting plants such as tomatoes, peppers, cucumbers, beans. Those plants have higher nutritional demands but will need more strict care conditions.
Herbivorous and omnivorous freshwater fish are ideal for their sustainability because of their easy eating habit. You can consider these fishes to grow in your systems such as tilapia, catfish, koi, goldfish, pacu, and crayfish.
How does an aquaponics system work?
Aquaponics systems comprise three components, each of which depends on each other to survive: the aquatic animals (the fish), the nitrifying bacteria, and the plants.
When fish food is put into the system, the fish will consume and transform it into urine fecal matter. If accumulated to a certain quantity, the excreted waste can be toxic to both plants and fish.
Biofilter plays a vital role in changing the ammonia-rich water and decaying plant matter into organic nutrient solutions under bacteria’s control. Then water in the tank is filtered for growing vegetables. Thanks to plants, the nutrients are absorbed and removed to leave the water clean for fish.
