Scottish Fish Farm Production Survey 2019
This report is based on the returns of an annual survey questionnaire sent to all active authorised fish farming businesses in Scotland during 2019. Statistics on employment, production and value are presented.
Executive Summary
The tables below summarise the results from the 2019 fish farms annual production survey (slight difference in these summary figures from figures in the main report are due to rounding).

Production of year 2 salmon (tonnes) | 45,224 | 70,860 |
Mean fish weight 0-year (kg) | 2.9 | 2.9 |
Mean fish weight grilse (kg) | 4.9 | 5.0 |
Mean fish weight pre-salmon (kg) | 5.2 | 5.1 |
Mean fish weight year 2 salmon (kg) | 6.3 | 5.8 |
Number of staff employed | 1,466 | 1,651 |
Mean productivity tonnes/person | 106.4 | 123.5 |
Production tonnage increased by 47,856 tonnes with an increase in the mean harvest weight of grilse but a decrease in the mean weight of pre-salmon and year 2 salmon. Staff numbers increased by 185 and mean productivity increased to 123.5 tonnes per person.
Survival (%) | Years 0+1 | Year 2 | Total |
---|---|---|---|
2016 input year class | 59.9 | 16.7 | 76.6 |
2017 input year class | 47.3 | 26.5 | 73.8 |
The smolt survival rate for the 2017 input year class decreased to 73.8%. Mortality is included in the number of fish not harvested for human consumption, which also consists of fish which have escaped, been culled for production reasons, removed for sampling purposes, statutory culls or selected for broodstock production.

Some figures are excluded from this report as providing them would reveal production information from an individual company.
aExcluding halibut production.
bExcluding halibut ova laid down to hatch.
In 2019, the production of other species increased by one tonne from the 2018 total, although this figure does not include halibut production. Overall, employment decreased by seven in 2019. There was a decrease in the number of ova laid down to hatch during 2019 and again any halibut ova laid down to hatch were excluded from this figure.
