Proposals for a risk-based framework for managing interaction between sea lice from marine finfish farm developments and wild Atlantic salmon in Scotland

We consulted in December on our outline proposals for the new, spatially based risk assessment framework for regulating the interaction between sea lice from marine finfish farms and wild Atlantic salmon.

The framework will be applied through the Water Environment (Controlled Activities) (Scotland) Regulations 2011.

We worked closely with scientists from Marine Scotland to develop the technical details of the proposed framework as well as with NatureScot and local planning authorities.

Input from stakeholder groups on the Salmon Interactions Working Group (finfish producers, fishery management organisations and environmental NGOs) was invaluable in helping shape and refine the framework during its development.

The proposed framework would be implemented by embedding it within our wider regulatory framework introduced in 2019, which already regulates all discharges from marine finfish farms to the water environment.

In total, we received consultation responses from 62 stakeholders.

We have published all stakeholder responses below, with personal information redacted.

We have read and considered all the responses and have made some changes to the framework as a result. We also held a series of workshops/engagement sessions in June 2022 to update stakeholders on changes to the framework and the implementation process that we were considering and take onboard any additional feedback and comments.

The main changes we intend to take forward are summarised below, alongside our full analysis of the consultation response.

• We have decided that sea trout should be included from the beginning of the framework. We will initially focus on providing protection of sea trout in Wild Salmon Protection Zones during the early sea phase of their lifecycle and the development of a sea trout monitoring programme that will provide information to help assess risk and further develop the regime.
   
• We will produce a further consultation in early 2023 detailing how the framework will operate in practice before implementing the regime. This consultation will include details of the choices we have made on controls that will apply and an assessment of the social and economic implications of the framework.
   
• To allow time for further consultation and development of risk screening models, we will now work towards starting to apply the framework to applications for proposed new farms and expansions of existing farms in the second half of 2023. However, it is important we get it right and, if necessary, we will take additional time if needed.
