Finfish aquaculture: Advertised applications under the Water Environment (Controlled Activities) (Scotland) Regulations 2011

Closes 30 Jun 2027

Opened 22 Apr 2021


SEPA, as one of a number of organisations regulating finfish aquaculture, will maintain a high quality environment by setting permit conditions which limit the impacts associated with fish farms and then by ensuring that operators comply with these conditions.

On this aquaculture hub, you’ll find a list of open consultations for marine pen fish farm applications. You can send us any comments here.

As part of our determination, SEPA will consider risks to the water environment (including potential impacts to marine species and habitats) and the interests of other users of the water environment resulting from an aspect of the proposed farm development that we regulate. 

Each consultation will be open for a minimum of 28 days.

How we use your feedback

As Scotland’s principal environmental regulator, our purpose is to protect and improve Scotland’s environment in ways that, as far as possible, also contribute to improving health and well-being and achieving sustainable economic growth. Our Corporate Plan 2024-2027 sets our strategic ambition and priorities. Our Annual Operating Plans set out how we will implement our priorities every year.

In delivering these priorities we engage with those who have an interest in and/or are affected by our regulations and duties. One way we engage is through formal consultations. This is your opportunity to tell us what you think about our proposals. The feedback we receive helps us to understand what matters most to people and how we can deliver our duties efficiently and effectively.

After the consultation closes, we’ll consider the information we receive before publishing a digest of responses through the We asked, You said, We did section of our consultation website. This will close the consultation process by explaining how we have considered and, where appropriate, acted upon what we heard.
