GROWTH of Scotland’s fish farming industry could lead to more seals being shot unless new non-lethal deterrents are developed to keep them away, experts say.
A paper by the Scottish Association for Marine Science found the sea mammals would face the biggest impact from proposed salmon sector expansion.
Acoustic deterrent devices (ADDs) are the most common form of technology used to resolve the issue in Scotland at present.
But academics have called for new non-lethal methods to be developed to discourage the predators from attempting to hunt farmed fish, as questions still surround the effectiveness of ADDs. The report said: “Current downward trends in seal shootings are encouraging but these may stabilise or reverse in case of significant future expansion of the industry including into more remote, exposed and/or offshore areas.
“Over the years, the Scottish salmon sector has invested heavily in ADDs as a non-lethal alternative to shooting seals, but significant fundamental questions remain about the mechanisms and long-term efficacy of ADDs in deterring seals.
The Review of the Environmental Impacts Of Salmon Farming in Scotland Report has been submitted to Parliament ahead of an investigation into the industry.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
