Global marine aquaculture industry is developing rapidly to make up the shortfall in protein supply for human consumption. Knowing prevailing current and water quality conditions through continuous monitoring could actually promote a longevity profitable offshore aquaculture farm. Aanderaa has provided monitoring systems for several Norwegian offshore Salmon farms. In a Singapore Aquaculture Farm, we have deployed Aanderaa systems to monitor current and water quality conditions. Field gathered information, as opposed to forecasted models shows higher variability of current velocities within fish farm concession area. Lower Dissolved Oxygen levels are found consistently at shallower depth as compared to deeper depths. Knowing these important prevailing field conditions can be used to understand and improve fish feeding timings, sea cage layout design, working environment safety conditions for divers, fish overcrowding, fish waste dispersion dynamics and water exchange between inside and outside sea cages.
