Aquaculture is the farming of aquatic organisms such as fish, shellfish and aquatic plants – it’s essentially agriculture, but in the water. Aquaculture is among the fastest growing food sectors in the world, accounting for nearly fifty per cent of the world’s total fish production. Marine aquaculture refers specifically to the culturing of oceanic species (as opposed to freshwater). Examples of marine aquaculture production include oysters, clams, mussels, shrimp, salmon and algae.
Oxygen levels in these aquacultures critical. During night time they can sink to dangerous levels. This is because the photosynthesis (in algae and similar plants) stops when the sun goes down and it gets dark.
However, the oysters, clams, shrimps, salmons etc…still need the oxygen.
Often this problem is solved by letting seawater come in to the pond during high tide to create a blend with the oxygen rich seawater.
However, the seawater is rich of bacteria and viruses as well. This means that the aquacultures can infected by various diseases. Various chemicals such as antibiotics in the water are used to prevent this.
FlowMixer can help keeping the oxygen levels up by offering a very effective way to aerate and a low energy input.
