🐟 Aquaponics is a sustainable gardening technique that combines fish and vegetables.

🌱 The vegetables in this aquaponic system are growing organically without the need for soil.

💡 The fish in the system produce ammonia, which is converted into nitrates by naturally occurring bacteria, providing nutrients for the plants.

🔧 Setting up an aquaponic system requires a fish tank, gravel grow beds, a water delivery system, and a way to return the water to the fish tank.

⚖️ The choice of growing media in the system can vary between gravel and expanded clay pebbles, with clay pebbles being lighter in weight.

🥬 Vegetables that grow above ground generally do better in aquaponic systems, such as garlic chives, silver beet, sweet corn, and cabbages.

🐟 Different fish species can be grown in aquaponic systems depending on the climate, such as Jade perch, silver perch, Murray cod, barramundi, and trout.

💰 Aquaponics requires investment and effort to set up and maintain, but it offers a sustainable gardening project with the added benefit of fresh fish and vegetables.
