Pond systems are bodies of fresh or brackish water that are used to culture aquatic organisms. These systems offer ease of management and use natural resources efficiently. However, they may require large areas of land and can be impacted by seasonal changes and extreme weather events.

Open-net pens are aquaculture enclosures placed in natural bodies of water, allowing water to flow freely. Benefits include lower costs and higher stocking density. Challenges encompass the risk of disease and pollution, escapement of farmed fish, and conflicts with wild fish populations.

Offshore aquaculture involves raising fish or shellfish in ocean waters typically deeper and farther from shore than traditional marine operations. The benefits include the vast space and clean water, which reduce disease and parasite risks. Challenges encompass regulatory hurdles, high costs due to logistics and infrastructure, and sensitivity to oceanic environmental changes.

RAS are tank-based systems that filter and recycle water, allowing for high-density farming of fish with a minimal water requirement. They are beneficial for controlling environmental conditions and reducing disease risk. Challenges include high initial and operational cost, complexity, and the need for constant monitoring and management.
