Abu Dhabi clamped down on illegal street vendors in Al Bateen.
It follows the seizure of 200 kilograms of dried fish that was found in the neighbourhood.
The campaign aims to prevent people from selling fish without a licence, stop the illegal drying of dish and prohibit dumping of fish waste in the sea.
Authorities said the move aimed to safeguard public health.
Inspectors visited the Bateen area and instructed fishermen not to co-operate with unlicensed vendors.
Bateen used to be a simple fishing village, with a 4x4 needed to navigate down sand tracks from Abu Dhabi's old town.
But over the past 30 years, it was become part of the city, with new hotels, restaurants and a marina opening.
The campaign, meanwhile, was undertaken in co-operation with the Abu Dhabi Agriculture and Food Safety Authority, Abu Dhabi Police and the Abu Dhabi Centre for Waste Management.
