Improving the health of farmed salmon

The Marine Challenge Programme improved salmon health in Irish sea pens by using a bubble curtain to reduce plankton influx and mitigate related health issues.

This project aimed to enhance the survivability of salmon in sea pens along Ireland's west coast by addressing health issues linked to increasing planktonic biomass in Irish waters. Over the past 4-5 years, rising plankton levels have caused fish health problems and, in severe cases, mortality. A collaboration between salmon producers, the Irish Seafood Development Agency (BIM) and plankton identification experts, the project explored the use of a ‘bubble curtain’ or ‘bubble screens’ in salmon farms. This innovative solution creates a virtual barrier around the fish pens, reducing the influx of planktonic species and thereby improving environmental conditions for the fish. 

Results

  • Reduced plankton influx and improved fish health in Irish salmon farms.
  • Mitigated health problems caused by rising plankton levels.
  • Ascertained the effectiveness of using bubble curtains despite challenges posed by Ireland's shallower sites and strong tides.
