Sustainable Water Solutions for Aquaculture

Aquaculture is a critical food source to meet current and future global consumption requirements.

The demand for quality seafood and sophisticated consumer purchasing trends have increased. This combined with the environmental and financial risks of off-shore aquaculture create the need for farmers to gain greater control over their operations. Land-based aquaculture is a solution for aquaculture companies to reduce risk, while maximizing profitability. 

Utilizing advanced recirculating aquaculture systems allows farmers to achieve a farm-to-table strategy by locating facilities on land near key markets. This reduces shipping costs and shortens delivery timeframes, while offering consumers a superior fresh product. 

Land-based aquaculture facilities create a means of producing seafood with a minimal impact on the fisheries and the environment, while reducing the carbon footprint of conventional seafood supply chains.
