It is essential to use sensor technology to monitor actual conditions in and around marine fish farming,
one of Norway’s largest export industries. The monitored data, together with research into effective
operation will provide productive management and also alleviate any negative environmental impacts.
Since 1966 Aanderaa has developed and manufactured instruments, sensors and systems for
oceanographic research related to the mapping of oceans and fjords. Our customers include marine
research institutes, cartography firms, oil companies and the military who set strict requirements for the
design, quality and accuracy of our sensors and instruments.
Many of the measurement data used in oceanographic research are also applicable when monitoring
the environment in fish farms. Aanderaa has recently developed separate systems intended for the
fish farming industry based on its long experience gained from the development of instruments for
research. Trustworthy intelligence about the environment the fish inhabit may prove the difference
between poor or healthy fish farming economics.

Monitoring Station
Aanderaa Environmental Station is a complete system designed to monitor critical parameters, both
in and outside the cage to ensure the best possible well-being and growth conditions for the fish. As
a minimum oxygen, temperature, current direction and current strength are measured, while other
parameters such as salinity can easily be added. All data are shown in real time via a graphical display
system, and historical data is stored for later use as a basis for trend analysis or comparison of farms to
optimize production performance.

Oxygen
Oxygen is the most important parameter. Low oxygen levels stress fish and increase the possibilities
of disease. During feeding, low oxygen levels can decrease the intake of feed and increase the feed
factor (feed use/economy).

Current
Good current conditions will ensure fresh oxygen rich seawater
flowing through fish farms. Information about the current strength
may also be used to limit the spread of feed outside cages.

Temperature
Temperature is also an important physiological parameter. Fish
have greatest appetite under optimum temperature conditions.
