“Matt Clarke, Co-founder of Poseidon Ocean Systems, said: ‘Not only is Flowpressor more effective at protecting farmed fish health than standard systems, it’s also 56% more fuel efficient, reducing CO2 emissions by as much as 700 tonnes for each unit installed. That’s the equivalent of taking 150 passenger vehicles off the road for one year.”

Scottish Sea Farms is to trial the potential of a new greener aeration system, Flowpressor, to protect its salmon from potentially harmful plankton, a major threat to the health and welfare of farmed fish worldwide.

Whilst many species and concentrations of plankton are vital to a healthy ecosystem, others can be harmful to humans and animals; in the case of farmed salmon, they can cause damage to the gills, depriving fish of oxygen.

Aeration – the process of pumping air into salmon pens to boost water movement and, in turn, water quality – is one of several protective measures taken by salmon farmers when rising levels of plankton are detected during daily water monitoring.

Standard aeration systems use generic industrial compressors to pump in this air but with mixed results; if air flows aren’t evenly distributed for example, then those pens closest to the compressor tend to receive the biggest boost of air.

The Flowpressor system, in contrast, has been custom designed for the aquaculture sector by Poseidon Ocean Systems in Canada where gill health challenges can be more intense with as much as 1.5-2 million cells per litre of algae compared to 50 to 1,000 in Scottish waters.
