Aquaculture and Environmental Impact

How can the environmental impact of high levels of nutrients from aquacultural operations be reduced?

1) Nutrient-rich fertilizers

2) Aquaponics systems

3) Chemical pesticides

4) Soil erosion

Answer:

Aquaponics systems can reduce the environmental impact of nutrient-rich runoff from intensive land-based aquacultural operations. The correct answer is option 2) Aquaponics systems.

The environmental impact of high levels of nutrients generated from intensive land-based aquacultural operations can be reduced by the use of Aquaponics systems.

Aquaponics is a sustainable method of farming that combines aquaculture (raising aquatic animals) and hydroponics (growing plants in water). In an aquaponics system, the waste produced by the fish is used as a nutrient source for the plants, which in turn filter the water and provide a clean environment for the fish.

This closed-loop system minimizes nutrient runoff and reduces the need for additional fertilizers, making it an effective solution to mitigate the environmental impact of nutrient-rich runoff from aquaculture operations.

Therefore, the correct answer is option 2) Aquaponics systems.
