By System Type

Open Loop System:

The open loop system is characterized by its reliance on external water sources, where the system draws in fresh water while discharging used water back into the environment. This type of system is commonly used in areas with abundant water supply, but it is less sustainable compared to other systems, as it does not effectively recycle water. While open loop systems can support a variety of species, their environmental impact and higher operational costs have led to a gradual shift towards more sustainable options. Nonetheless, they still play a role in traditional aquaculture practices, particularly in regions where water resources are underutilized.

Closed Loop System:

Closed loop systems are highly efficient as they are designed to recycle water within the system, significantly reducing water usage and environmental impact. This type of system employs advanced filtration and sterilization methods to maintain water quality, making it suitable for various species, including both freshwater and saltwater fish. Closed loop systems provide better control over the aquaculture environment, allowing for optimal growth conditions and higher stocking densities. The rising demand for sustainable seafood and the need for reduced water consumption are driving the adoption of closed loop systems across the globe.

Semi-Closed Loop System:

Semi-closed loop systems combine features from both open and closed loop systems to balance efficiency and environmental impact. They allow for partial water recycling while also drawing in fresh water to maintain water quality. This hybrid approach enables aquaculturists to benefit from reduced water consumption without entirely relying on closed systems. Semi-closed loop systems are gaining traction among mid-sized fish farms looking for more sustainable options without the investment required for fully closed systems. Their flexible design and scalability make them suitable for various applications and species.

By Application

Freshwater Fish:

The freshwater fish segment holds a significant share in the recirculating aquaculture market, driven by the increasing popularity of species such as tilapia, catfish, and trout. These species are favored for their fast growth rates and adaptability to controlled environments.
