6. WHAT METHODS WERE USED TO IDENTIFY PROPOSED WATERS FOR DESIGNATION?
In order to identify proposed waters for designation under the SWD, we analysed data from various sources. We looked at data supplied by Fisheries Research Services ( www.marlab.ac.uk) on production by site, compiled from returns provided by registered shellfish farming operations. Returns for the past four years 2002 - 2005 were used for the purpose of this consultation - a run of years is considered because we know that some species are slow growing and take time to reach harvesting size, and because the practice of fallowing may introduce gaps in production.
Examination of this data from the past four years has enabled us to compile a list of sites at which we believe sustainable production is taking place. The Food Standards Agency (Scotland) ( www.foodstandards.gov.uk) also provided us with information on SHD waters. Where possible, the boundaries of the proposed new sites have been matched with the relevant existing SHD designations.
