47. Land-based aquaculture sites and fishing ponds operated by holders of an aquaculture or fishing pond licence on 9 July 2008 are exempt from the application of paragraphs 4, 5 and 8 of section 28 and paragraph 6 of section 31 as regards the infrastructures, equipment and facilities built and used on that date.
