People have been warned not to eat shellfish from three sealochs on the east coast of Harris due to potentially dangerous toxins.
High levels of marine biotoxin are present in the Sound of Scalpay in East Loch Tarbert as well as Loch Stockinish.
The third area covered by the warning is Loch Seaforth between Harris and Lewis.
Eating shellfish such as mussels, cockles or razor fish from these areas may pose a risk to human health.
According to the council, notices to warn the public and casual gatherers have been posted at various locations on the shore.
Commercial shellfish harvesters in these areas have been contacted by the Comhairle and steps taken to postpone harvesting until algae levels subside.
