Scottish Fish Farm Production Survey 2025

Introduction

The annual production survey of fish farms in Scotland for 2025 was carried out by the Marine Directorate of the Scottish Government. This survey collates annual production data from Scottish fin fish farm sites operated by authorised aquaculture production businesses. These are Official Statistics published in accordance with the Code of Practice for official Statistics. The production tonnage obtained is for the wet weight (i.e. weight of live fish) at harvest.

Responses to questionnaires from Scottish fish farming companies covering the period 1st January to 31st December 2025 are summarised in this report and responses were received from 100% of companies. The questionnaires are provided in the Supplementary Questionnaire Documentation. The survey is structured to allow readers to follow trends within the rainbow trout, Atlantic salmon and other farmed species sectors. Data from previous years have been reassessed and updated where necessary. To allow direct comparison with data provided in previous surveys, production information by region is presented in defined production areas. Data relating to production carried out in Na h-Eileanan Siar will be labelled as the Western Isles to maintain consistency with historical data sets.

To meet current accessibility legislation parts of this report have been reformatted. Where tables have had to be removed or reduced in size to meet accessibility requirements the full data sets are available in the Scottish Fish Farm Production Survey 2025, Supplementary Tables. Historical data are available on the Marine Directorate Data Publishing Portal, Scottish Fish Farm Production Survey Data | Marine Scotland Data Publications, as well as in the new Scottish Fish Farm Production Survey 2025, Supplementary Tables. Also, Table 17 and Chart 31 exclude production figures for larval stage cleaner fish which may be traded for on-growing at facilities outwith Scotland, shortly after hatching. These now refer only to cleaner fish large enough to deploy on salmon farms. Trade in larval stage fish are included in Table 19.

The cooperation of the Scottish fish farming sector in completing the questionnaires is gratefully acknowledged.
