Aquaculture: Environmental Impact and Challenges

Aquaculture is the farming of food in marine and freshwater environments, utilizing land-based practices. It encompasses a wide range of species, including ornamental ones, and various systems like indoor tanks and ocean net pens. Despite misconceptions, aquaculture can be sustainable and produce nutritious food with less environmental impact than terrestrial proteins. As ocean biomass is maxed out, aquaculture is crucial for increasing seafood supply sustainably. If managed well, it holds potential as a key source of human nutrition.
