Aquaculture is the commercial farming and harvesting of aquatic animals and plants under controlled conditions. It provides many benefits such as ensuring a steady food supply, high food conversion ratios, prolific breeding, utilizing three-dimensional space, and efficiently recycling waste. Aquaculture can be classified based on factors like salinity, temperature, economic aspects, culture techniques, integration with other industries, and type of organisms cultured.
