What is the practice of fish farming called?

The practice of fish farming is called aquaculture. This term encompasses the breeding, rearing, and harvesting of fish, crustaceans, mollusks, aquatic plants, algae, and other organisms in various water environments, including ponds, rivers, lakes, and oceans. The main focus of aquaculture is the production of aquatic organisms for food and other products, which allows for sustainable practices that can help meet global food demands.

Hydroponics, on the other hand, refers specifically to growing plants in a water-based, nutrient-rich solution without soil, and is not concerned with the farming of fish. Aquaponics combines aquaculture with hydroponics, where fish are raised alongside plants, utilizing the waste produced by the fish to provide nutrients for the plants. Pisciculture, while related, specifically refers to the cultivation and breeding of fish, but aquaculture is the broader term that includes not only fish farming but also the farming of other aquatic organisms. Therefore, aquaculture is the most accurate term to describe the practice of fish farming as it encompasses the entire field of aquatic farming.
