Extensive aquaculture relies on natural resources to support the growth of aquatic species, minimizing artificial inputs like feed and aeration. Typically practiced in large ponds or coastal areas, it depends on natural nutrients and water flow, making it a sustainable and low-cost farming method. This approach is particularly suited to species that thrive with minimal intervention, such as certain types of fish and shellfish. While productivity is lower compared to intensive systems, extensive aquaculture has a smaller environmental footprint and helps conserve ecosystems. It’s especially valuable in rural areas, providing income and food security without significant resource investment.
