Aquaculture data has been provided via special request, by the Department of Agriculture, Food and the Marine for reporting on aquaculture activities under Ireland's Marine Strategy Framework Directive article reporting. Aquaculture sites include shellfish, finfish and seaweed as monitored for licensing purposes. Data has been displayed by the theme, Shellfish By Culture Type and By Species Type; Finfish By Culture Type and By Species Type; Seaweed By Culture Type and By Species Type. Aquaculture sites are updated periodically. Fishery order areas are assigned to local co-operatives or private individuals through Fishery Orders (under the 1959 Fisheries (Consolidation) Act (no. 14 of 1959)). Aquaculture is licensed under the Fisheries (Amendment) Act, 1997 (No. 23 of 1997) and its associated Regulations. This dataset aims to present an illustration of the economic activity which is currently being undertaken in Irish waters with regards to aquaculture processes as described in the abstract.
