Aquaculture techniques involve the farming of aquatic organisms such as fish, shellfish, and plants in controlled environments. These methods can include pond culture, where fish are raised in large, shallow ponds, and recirculating aquaculture systems (RAS), which filter and reuse water to maintain a healthy habitat. This approach helps to produce seafood sustainably while minimizing environmental impact. Another common technique is mariculture, which focuses on cultivating marine organisms in their natural habitats, like oceans or estuaries. This can involve net pens for fish or oyster beds for shellfish. By using these methods, aquaculture supports food security and provides livelihoods for many communities.
