An inspection of Mowi Scotland’s salmon farms following storm Brendan last week revealed damage to one net pen at the company’s Colonsay location. 

Mowi has confirmed a loss of 73,600 salmon (average weight 1.9 kilograms) from one net pen, after recount. The loss of fish has been reported to the regulator.

The post-storm inspection revealed structural failure of the pen, causing a tear in the netting. Other net pens on site are confirmed secure. 

“We are very disappointed that this structural failure has occurred,” says David MacGillivray, Mowi’s regional farm manager. “Despite storm Brendan severely battering many parts of Scotland’s coast last week and Colonsay being a remote and particularly exposed location, we expect our modern infrastructure to withstand these challenges.”

The farm’s net pens exceed both the Scottish and Norwegian technical standards for net pen design. The company and equipment supplier are immediately reviewing the net pen’s manufacturing process. 

No staff were injured during storm Brendan.
