Question 1

Kerala's marine fisheries sector is vital for the state's economy and food security but faces significant challenges regarding resource depletion and ecological balance. Considering both the livelihoods of fisherfolk and the long-term health of marine ecosystems, which of the following strategies is most crucial for ensuring the sustainability of marine fisheries in Kerala?

Accepted Answer

A. Promoting unregulated year-round deep-sea trawling to maximize catch volume and export potential.
