Have you heard of aquaponics before? It is a modern farming system that combines fish farming (aquaculture) with growing crops without soil (hydroponics). In simple terms, you raise fish in a tank and use their waste as fertilizer for plants. The plants, in return, clean the water, which goes back to the fish.
This creates a natural cycle where both the fish and crops benefit each other.
How It Works
Fish Tank: You keep fish like catfish or tilapia in water.
Fish Waste: As the fish eat and grow, they produce waste in the water.
Grow Beds: The water carrying the waste is pumped into grow beds where crops are planted in gravel or other media.
Bacteria Action: Helpful bacteria change the fish waste into nutrients that plants can use.
Clean Water: The plants absorb the nutrients, and the clean water flows back to the fish tank.
