Aquaponics System Overview

Explain the concept of Aquaponics System

• Combination of aquaculture technology and hydroponic system

• Only for growing fish

• A method of traditional farming

• A type of hydroponic system

List the advantages of Aquaponics System

• Optimum space and area

• Requires high energy

• Difficult to manage

• High initial cost

• All answers above

What are the characteristics of fish in Aquaponics System?

• Can tolerate adverse conditions

• Only eat specific types of food

• Require constant monitoring

• Grow slowly

• All answers above

Identify the equipment for fish culture in aquaponics

• Tank fish, Pump, Auto feeder

• Only a tank

• Soil and seeds

• None of the above

What is the pH level preferred in aquaponics?

• 7

• 5

• 10

• Neutral is not important

What are the important routine management practices for fish and plant culture?

• Food management is essential for health, growth and vitality of the fish.

• A good water level helps the roots of the crop to breathe and grow well.

• Good feeding for fish will help to supply the enough nutrients for plant.

• The plant media plays an important role for the growth of crop roots.

• All answers above

What are the daily activities for routine management practices?

• Check the water and pumps are working well.

• Feed the fish two times a day.

• Check the plant for pest.

• Remove any sick plant/branches.

• All answers above

What are the weekly activities for routine management practices?

• Perform water quality test for pH, ammonia, nitrite and nitrate.

• Check the plants looking for deficiencies.

• Clear the fish waste from the bottom of fish tank.

• Harvest plant and fish if required.

• All answers above

What are the monthly activities for routine management practices?

• Stock new fish in the tanks.

• Clean out the biofilter, clarifier and all the filters.

• Clean the bottom of the fish tank.

• Weigh a sample of fish and check thoroughly for any disease.

• All answers above

What are the optimal water quality values for productive and well-performing aquaponics systems?

• Temperature: 65–85°F, pH: 6–7, TAN: <1 ppm, NO2: <1 ppm, NO3: 5–150 ppm, DO: >5 ppm

• Temperature: 81–84°F, pH: 7, TAN: <1 ppm, NO2: <1 ppm, NO3: 5–150 ppm, DO: >5 ppm
