Marine aquaculture is one of Scotland’s most important rural industries.
More than 8,000 people are employed in farming shellfish, salmon, trout and related industries, mostly in remote locations where other job opportunities are scarce.
Seaweed farming is an emerging sector in Scotland, which has the potential to become commercially significant in the future.
Our role
We provide leases for area of seabed which are used to:
- Farm finfish, such as salmon and trout
- Farm shellfish, such as mussels, scallops and oysters
- Farm Seaweed.
We also provide licences for seaweed harvesting on Crown foreshore and seabed. We only issue these licenses once NatureScot confirm they are satisfied that there is no evident risk of unacceptable environmental impacts.
We are not a regulator and will not issue a lease unless all other necessary statutory consents are in place.
How we contribute
As well as awarding and managing leases, we contribute to the success of aquaculture in Scotland through measures that include funding research projects and business and stakeholder development positions with industry organisations. We have also worked with the Scottish Government to create an online overview of the industry in Scotland.

In 2022 we finalised our ‘root & branch’ review of aquaculture lease terms.
Details of changes will be included in the individual Business Resource pages – see below - but notable changes include:
- An annual Reporting requirement on Management of Marine Plastics for all tenants, and on participation in Collaborative Management Agreements for finfish tenants
- All tenants will be required to submit an annual Declaration of what equipment they have deployed on leased sites and confirm its secure installation and well-maintained condition
- Changes to the way rents are assessed and an option to renew for finfish leases
- Charges have been introduced for Lease Option Agreements and these have also had the statutory consent deadlines extended by a year, providing a longer period for grantees to prepare applications for regulatory authorities
Crown Estate Scotland is currently involved in various discussions and projects relating to natural capital, including assessment methodologies, validation, markets and associated trading of credits relating to carbon, biodiversity and nutrients.
Natural capital markets are more advanced for land-based assets, but there is increasing interest in scope for the marine environment to offer similar tradeable credits.
Work has however yet to be concluded that can provide the same assurance and validation for marine assets that, for example, the Woodland and Peatland Codes do for terrestrial ones.
Therefore to avoid unhelpful speculation in such matters ahead of clear validated mechanisms for assured identification and valuation of tradeable credits based on marine natural capital becoming available, all aquaculture leases to be issued from now on will include a condition that prohibits trading in natural capital credits, including offsetting, on leased subjects (seabed/foreshore) without our prior written consent.
