In September 2008 a No Take Zone (NTZ) was established in Lamlash Bay (Isle of Arran, North Ayrshire) in Scotland following a consultation for a fishery order (under the Inshore Fishing (Scotland) Act 1984). The proposed NTZ was passed by the Scottish Parliament prohibiting all sea fishing within the NTZ. The main aims of this survey were to carry out an acoustic mapping survey with ground-truthing (camera deployments and sediment sampling) to create maps of the habitats and biotopes within the site in a Geographical Information System (GIS). The field work (acoustic and biological surveys) was undertaken between the 13th and 21st October 2008 with all survey operations conducted from the Fisheries Research Services (FRS) survey vessel Alba na Mara.
