The annual production survey of fish farms in Scotland for 2011 was carried out
by Marine Scotland Science (MSS). This survey collates annual production data from
Scottish fin fish farm sites operated by authorised aquaculture production businesses.
Surveys conducted by other organisations are produced independently of MSS and may
not be directly comparable. The production tonnage obtained is for the wet weight of
fish at harvest.
Responses to questionnaires from Scottish fish farming companies covering the period
1st January to 31st December 2011 are summarised in this survey. The questionnaires
are given in Appendix 1a-d. The survey is structured to allow readers to follow industry
trends within the trout, salmon and other farmed species sectors. Some statistics
are given for the 21-year period 1991-2011. Data from previous years have been
reassessed and updated where necessary. To allow direct comparison to data provided
in previous surveys, production information by region is presented in defined areas.
