Aquaculture raising, often called aquaculture, is the practice of cultivating aquatic organisms under controlled conditions for food, restoration, or other uses. It covers fish, crustaceans, mollusks, seaweeds, and other aquatic organisms. It contrasts with wild harvest and aims to produce reliable yields.

Common methods include open systems such as earthen ponds and marine nets in natural waters, and closed or semi-closed systems such as recirculating aquaculture systems (RAS), biofloc systems, or flow-through tanks. In coastal regions, cage farming in seas or bays is common; inland operations often use ponds or raceways.

A typical operation includes broodstock management, hatchery production of fry or larvae, and grow-out phases in adjusted water conditions. Feeding is a major cost, with formulated pellets tailored to species. Water quality management is critical, monitoring temperature, dissolved oxygen, salinity, pH, ammonia, nitrite, and nitrates. Disease prevention and biosecurity are essential, with vaccination, sanitation, and quarantine.

Sustainability concerns include nutrient discharge, habitat disturbance, genetic interactions from escaped stock, and feed sustainability (protein sources). Best practices include responsible siting, effluent treatment, integrated multi-trophic aquaculture, and improving feed efficiency. Economic considerations include capital costs, operating costs, market demand, and regulatory compliance.

Regulation and certification programs may govern welfare, environmental impacts, and product labeling. Aquaculture is a growing sector that supplements capture fisheries and provides local employment, but its growth depends on environmental stewardship and efficient production.
