What does aquaculture involve?

Aquaculture involves the farming of aquatic animals, which includes the breeding, rearing, and harvesting of species such as fish, shellfish, and aquatic plants in controlled environments. This practice allows for the production of seafood in a sustainable manner to meet growing food demands. In aquaculture, a variety of techniques are employed to create ideal living conditions for aquatic species, ensuring their health and growth.

Raising terrestrial animals pertains to livestock farming on land, which falls outside the scope of aquaculture. Planting crops in water may refer to hydroponics or aquaponics, but it does not align with the specific focus on raising aquatic animals. Collecting natural aquatic resources usually involves catching wild fish or foraging for naturally occurring aquatic life, instead of the controlled breeding and farming processes characteristic of aquaculture. Therefore, the emphasis on cultivating aquatic species in a structured environment defines the core of aquaculture, making the choice of raising aquatic animals on farms the correct answer.
