The incident took place on March 25 and the reason for the escape was described on the Scottish government’s aquaculture website as “predator” – most likely a seal.
The average weight of the salmon, which were due to be harvested next year, was 1.3kg. If the escaped fish had grown to reach 5kg in that time, it is estimated they would have added approximately 100 tonnes of fish.
The wrasse, which were being used as cleanerfish, had an average weight of 60 grams.
A spokeswoman for Scottish Sea Farms told fishfarmingexpert.com: “I can confirm that the escape took place. It was due to net failure and an investigation has been launched.”
The incident is believed to be the biggest escape to have occurred in Scotland since May 2016, when 30,000 fish escaped a site in the Outer Hebrides.
In 2009, an estimated 37,000 Atlantic salmon parr escaped from a Scottish Sea Farms site on Loch Frisa, a freshwater loch near Tobermory on Mull.
