The primary ecological benefit of sustainable aquaculture is reduced overfishing of wild stocks, helping to maintain healthier marine ecosystems.

Sustainable aquaculture allows for the production of seafood without putting additional pressure on wild fish populations. By farming species in controlled environments, aquaculture reduces the need to harvest wild fish, helping to preserve biodiversity and avoid the depletion of natural resources. Sustainable practices, such as using responsible feed and managing waste, also mitigate the environmental impacts of aquaculture, ensuring that fish farming can coexist with healthy marine ecosystems. This approach supports both food security and conservation efforts.
