Scottish Fish Farm Production Survey 2022

This report is based on the returns of an annual survey questionnaire sent to all active authorised fish farming businesses in Scotland during 2022. Statistics on employment, production and value are presented.


3. Atlantic Salmon - Production

Production

Production survey information was collected from all 10 companies actively involved in Atlantic salmon production, farming 210 active sites. This figure represents the entire industry operating in Scotland.

In 2020, the last year for which survival can be calculated, the survival rate from smolt input to harvest increased to 75.9%. Of the 2021 year class, 50.4% of the input has been harvested, 6.8% lower than the average harvest of fish one year after input in the 2020 year class. In 2022, 0.1% of the fish were harvested from the 2022 input. This was an increase compared with the proportion of fish harvested from the same year class in 2021.

The total number of smolts put to sea in 2022 was just under 55.3 million. This smolt input comprised S½s (52%) and S1s (48%). No S1½s were produced in 2022. Two percent of the smolts stocked to Scottish salmon farms were sourced from outwith Scotland and no smolts coming from sources outwith GB in 2022. This was a decrease of 1% compared with the proportion observed in 2021.

The practice of putting smolts to sea in one region and subsequently moving them to another sea water site in another region for harvest can lead to an overestimation of survival in some regions and underestimation in others.

In 2022, the total number of staff employed in salmon production was 1,508, an increase of 13 compared with 2021. The staffing figures collected refer specifically to the production of Atlantic salmon and do not include figures for staff involved with processing or marketing activities. Productivity decreased from 137.4 to 112.2 tonnes produced per person.

Production Methods

In 2022, the majority of fish were produced in seawater pens. There were 17 tonnes of production from seawater tank sites in 2022. This reflects the high installation and running costs incurred in operating seawater tank systems. Most seawater tank capacity has been re-deployed for the production of other species of marine finfish or salmon broodstock.

Sea pen capacity increased by 2,902,000 m3 during 2022 and the number of sea pen sites in production decreased by three. Production efficiency in sea pens, measured as the ratio of fish weight in kilograms produced per cubic metre, decreased from 9,3 kg/m3 in 2021 to 6.7 kg/m3 in 2022.

* Includes farms stocked but having no production.

In 2022, the number of sites with no production increased by 14 and the number producing 1 to 1,000 tonnes decreased by two. The number of sites producing 1,000 to 4,000 tonnes decreased by 14 and sites producing over 4,000 tonnes decreased by one. The trend towards production in larger sites continued, with 86% of production being derived from sites producing over 1,000 tonnes.

The greatest productivity of 121 tonnes per person was achieved in the companies producing over 10,001-30,000 tonnes. The least productivity of 0.9 tonnes per person was from the companies producing between 0-1,000 tonnes. In comparison with 2021, the average company productivity decreased from 137 to 112 tonnes per person. Overall, production was dominated by two companies in 2022 which between them accounted for 60% of Scotland's farmed Atlantic salmon production.

The number of companies authorised and actively producing Atlantic salmon in 2022 was eight, two less than in 2021. Two companies remained active and authorised, although not producing salmon for harvest in 2022. These 10 companies had 210 registered active sites, although not all these sites produced fish for harvest in 2022.

Of the 209 seawater pen sites recorded as being active in 2022, 29 sites were fallow for the entire year whilst 147 sites were fallow for a variable period. There were 33 sites that did not fallow in 2022. The normal production cycle in seawater varies in length between 12 months and two years. A fallow period at the end of production can break the cycle of disease or parasitic infections.

Broodstock Sites

In 2022, the number of freshwater and seawater sites holding broodstock remained at four sites. A total of 3,166 fish were stripped, yielding 53.2 million ova, giving an average yield of 16,804 ova per fish.
