Farming of fish such as salmon, seabass, snapper, grouper, etc. is the most common form of aquaculture (or aquafarming) which involves a controlled farming within a closed-loop water recycling system.  As such, the aquaculture water recycling system plays an important component to ensure the availability of a high quality water consistently in order to support the fish health and growth.  

Waste management such as nutrient discharge also has to be monitored  and managed carefully to reduce the environmental impact.  This will help to improve the quality of the aquatic resources and in turn, maximize the profitability and sustainability for the aquaculture production.

Featured Applications

Recirculating Aquaculture Systems (RAS)


Water quality has an impact on the fish quality in the aquaculture industry.  The toxicity associated with nitrite and an excessively high level of nitrate in the tanks can impact the fishes health and growth.  Therefore, accurate monitoring of nutrient concentrations in the Recirculating Aquaculture System (RAS) during the entire production cycle is essential.  

Excess feeding represents a significant operating cost and feed not consumed by the fishes can increase nitrogen waste in the system.

With our accurate Nitrite and Nitrate analysis using ion chromatography and UV LED detection, our analyzer can measure the specific nitrite and nitrate levels in real time.  This will help provide an understanding of the biofilter performance and also assist in operational decisions such as  feed frequency to achieve optimization of biomass growth.
