Around 2,000 people have attended a protest against plans for a major fish farm off the Aran Islands in Galway.
The facility would be the largest of its kind in Europe and would double the State's production of raw organic salmon.
The plans have been met by strong opposition from fishery groups and anglers, citing fears of pollution and threats to tourism in the area.
Bord Iascaigh Mhara said the project would adhere to the strictest environmental standards.
A spokesperson for the Department of Agriculture said the BIM aquaculture licence application is under consideration by the Department in accordance with the provisions of the 1997 Fisheries (Amendment) Act.
“It would not be appropriate for the Department to comment further on an application which is under active consideration as part of a statutory process,” the statement added.
