Efficient Farming with Aquaponics

Aquaponics combines aquaculture and hydroponics, using less water and turning each method's downsides into benefits. It involves growing fish and plants together, where fish waste provides nutrients for plants, and plants clean the water for fish. The nitrogen cycle plays a crucial role in converting fish waste into plant nutrients. Various methods, such as using IBCs, floating rafts, and different media, can be employed to grow plants in aquaponics systems.

What is the main advantage of combining aquaculture and hydroponics in an aquaponics system?

• It reduces the need for sunlight.

• It turns the negative aspects of each method into positives.

• It eliminates the need for water.

• It increases the growth rate of fish.

In an aquaponics system, what role do bacteria play?

• They act as a medium for plant roots.

• They help in the growth of fish.

• They convert ammonia wastes into nitrates for plants.

• They provide oxygen to the fish.

Which of the following is NOT a method of growing plants in an aquaponics system?

• Floating foam rafts

• Media-filled grow beds

• Nutrient film technique (NFT)

• Soil-based planting

What is the purpose of removing a percentage of fish water daily in an aquaponics system?

• To reduce the temperature of the water.

• To ensure the fish have enough space.

• To increase the oxygen level in the water.

• To manage nutrient levels and support plant growth.

Which media can be used for planting in an aquaponics system?

• Wood chips and sawdust

• Sand and soil

• Coir peat, vermiculite, and perlite

• Plastic beads
