Mr Scott said such a move would help Scotland's fish farmers, harbour operators and marine renewable energy projects.
He also said it would make it easier for Shetland to obtain an interconnector cable so that it could export wind-generated electricity to the UK mainland.
Mr Scott has called on the Westminster government to investigate the idea of including such measures in the proposed UK Marine Bill, as suggested by the Crown Estate Review Working Group.
The working group has suggested the property, rights and interests of the Crown Estate in Scotland should be devolved to the Scottish Executive, just as has happened with the Forestry Commission.
