This report is based on the returns of an annual survey questionnaire sent to all active authorised shellfish farming businesses in Scotland. The cooperation of the shellfish farming industry is gratefully acknowledged. Production survey questionnaires were sent to 154 businesses registered as active during 2011. All return forms were received. During 2011, six businesses became authorised and sixteen business had their authorisations revoked. The survey showed that, of the 153 businesses authorised at the end of 2011 and included in this report, 68 recorded no sales during that year. These 153 authorised businesses farmed 335 active sites, of which 161 (48%) placed shellfish on the market.
Shellfish production by business and site is presented.
