Aquatic resource utilization refers to the responsible and sustainable use of water, fish, shellfish, and other aquatic organisms for food, economic, and ecological benefits. In aquaculture, efficient utilization of resources such as water, energy, and feed is essential to minimize environmental impact. Integrating practices like recirculating aquaculture systems (RAS) and multi-trophic aquaculture can improve resource use and reduce waste. Sustainable harvesting methods, along with responsible resource management, ensure the long-term viability of both wild fisheries and aquaculture. Proper utilization of aquatic resources can increase food security, support livelihoods, and contribute to the global effort of conserving aquatic ecosystems for future generations.
