Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Sewage-fed aquaculture utilizes treated or diluted domestic wastewater as a nutrient-rich source to promote plankton growth, which in turn feeds cultured fish.
Step 2: Detailed Explanation:
The state of West Bengal is globally renowned for its extensive, productive sewage-fed aquaculture systems.
The East Kolkata Wetlands (EKW) represent the largest wastewater-fed aquaculture system in the world.
In this system, domestic sewage from Kolkata is naturally treated through a series of oxidation ponds (locally called "bheries") and used to farm carps.
This highly sustainable practice provides significant fish supply to the local markets of Kolkata.
Step 3: Final Answer:
Sewage-fed aquaculture is most common in West Bengal.
Sewage-fed aquaculture utilizes treated or diluted domestic wastewater as a nutrient-rich source to promote plankton growth, which in turn feeds cultured fish.
