Aquaculture

Fish farming is one of Scotland’s most important industries. More than 8,000 people are employed in shellfish and salmon farming and related industries, mostly in remote locations where other job opportunities are scarce.

Fish farming operations require a Crown Estate Scotland lease. However, we are not a regulator and have no statutory function in relation to the fish farming industry. Planning consent is issued by local authorities. We currently lease around 750 sites to fish farm operators to grow finfish and shellfish. 

We licence seaweed harvesting to help ensure it is sustainably practiced with regard to possible impacts of harvesting on a range of factors (the stock itself, habitat and feed provision, coastal processes, etc). Proposals are only licenced if SNH confirm their satisfaction with its sustainability.

Supporting the industry

We invest in research and other activities to help fish farming secure a sustainable future.

  • We see commercial potential in seaweed farming and are exploring this in line with the Scottish Government's draft National Marine Plan
  • We have worked with government to create a detailed and up-to-date web-based overview of the Scottish industry
  • We continue to support the Scottish aquaculture research 
  • In discussion with the Association of Scottish Shellfish Growers, we recently commissioned an £18,000 investigation into a model to evaluate critical mass for economically viable shellfish production at loch/area-wide level
