Aquaponics: Integrating Fish and Plant Culture (1st/2nd)

What is aquaponics?

• The combined culture of fish and plants in recirculating systems

• The process of growing plants without soil

• The production of fish in small volumes of water

• The treatment of water to remove toxic waste products

Why are aquaponics systems easier to operate compared to hydroponic systems or recirculating fish production systems?

• They require less monitoring

• They have a wider safety margin for ensuring good water quality

• They have a larger capacity for fish production

• They are more cost-effective

What is the role of plants in an aquaponic system?

• Filtering water before it returns to the fish tank

• Producing fish waste

• Converting fish waste into nitrates

• Treating water to remove toxic waste products

What are aquaponic systems designed to do?

• Raise large quantities of fish in small volumes of water

• Grow plants without soil

• Remove toxic waste products from water

• Reuse water multiple times

What are integrated systems in aquaponics?

• Systems that grow additional crops using by-products from the primary species

• Systems that combine fish and plant culture in recirculating systems

• Systems that treat water to remove toxic waste products

• Systems that raise large quantities of fish in small volumes of water

How do plants in aquaponic systems receive their required nutrients?

• Directly from fish excreta

• From the breakdown of fish wastes by bacteria

• From the water in the fish tank

• From the soil in the system

What is the preferred form of nitrogen for growing higher plants in aquaponic systems?

• Ammonia

• Nitrite

• Nitrate

• Algae

What are the benefits of aquaponic systems?

• Recovering waste nutrients by the plants

• Reducing water discharge to the environment

• Minimizing water exchange costs

• Improving profit potential

What is the advantage of having a secondary plant crop in an aquaponic system?

• It helps balance pH levels

• It reduces the need for water exchange

• It improves the system's profit potential

• It eliminates the need for biofilters

What are the characteristics of aquaponic systems?

• Require less water quality monitoring

• Require a large capital investment

• Require high energy inputs

• Require skilled management
