Concerns over jobs have dogged the merger process |
It follows a decision by owners Marine Harvest to amalgamate the operation with Pan Fish Scotland and sell the combined company.
This overrides a previous decision to make the Stornoway operation a stand-alone company.
Fjord Seafood, which supports more than 100 fish farming jobs, has been rebranded Outer Hebrides Seafood.
Marine Harvest was told by the Competition Commission that it had to sell Pan Fish Scotland to be allowed the three-way merger with Pan Fish and Fjord Seafood worldwide.
It announced two months ago that Fjord's operation in Stornoway would be rebranded Outer Hebrides Seafood.
