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.
