Production

Production survey information was collected from all 11 companies actively involved in Atlantic salmon production, farming 232 active sites. This figure represents the entire industry operating in Scotland.

In 2018, the last year for which survival can be calculated, the survival rate from smolt input to harvest increased to 75.9%. Of the 2019 year class, 55.8% of the input has been harvested, 2.2% lower than the average harvest of fish one year after input in the 2018 year class. In 2020, 0.6% of the fish were harvested from the 2020 input. This was the same as the proportion of fish harvested from the same year class in 2019.

The total number of smolts put to sea in 2020 was over 52.4 million. This smolt input comprised S½ (47.3%) and S1s (52.7%). Four percent of the smolts stocked to Scottish salmon farms were sourced from outwith Scotland, 2% of which came from sources outwith GB. This was an increase of 2% compared with the proportion observed in 2019.

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 2020, the total number of staff employed in salmon production was 1,630, a decrease of 21 compared with 2019. 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 123.5 to 117.9 tonnes produced per person.

In 2020, the majority of fish were produced in seawater cages. There were 18 tonnes of production from seawater tank sites in 2020. 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 cage capacity increased by 1,190,000 m3 during 2020 and the number of sea cage sites in production increased by seven. Production efficiency in sea cages, measured as the ratio of fish weight in kilograms produced per cubic metre, decreased from 9.4 kg/m3 in 2019 to 8.4 kg/m3 in 2020.

In 2020, the number of sites with no production increased by 21 and the number producing 1 to 500 tonnes decreased by one. The number of sites producing over 500 tonnes decreased by 14 and the trend towards production in larger sites continued, with 89.6% of production being derived from sites producing over 1,000 tonnes.

The greatest productivity of 123 tonnes per person was achieved in the companies producing over 2,000 tonnes. The least productivity of 0.5 tonnes per person was from the companies producing between 0-100

tonnes. In comparison with 2019, the average company productivity decreased from 124 to 118 tonnes per person. Overall, production was dominated by six companies in 2020 which between them accounted for 99% of Scotland's farmed Atlantic salmon production.

The number of companies authorised and actively producing Atlantic salmon in 2020 was eight, the same number as in 2019. Three companies remained active and authorised, although not producing salmon for harvest in 2020. This continued the trend of Atlantic salmon production becoming concentrated within fewer companies. These 11 companies had 232 registered active sites, although not all these sites produced fish for harvest in 2020.

Of the 231 seawater cage sites recorded as being active in 2020, 45 sites were fallow for the entire year whilst 129 sites were fallow for a variable period. There were 57 sites that did not fallow in 2020. 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

Table 38: Number of sites holding Atlantic salmon broodstock during 2011-2020
Year 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020
Broodstock sites 11 7 8 8 4 3 4 4 3 4

In 2020, the number of freshwater and seawater sites holding broodstock increased to four sites. The number of sites holding broodstock in any one year can be variable, as can be seen from the previous years' figures, which indicate no obvious trend. A total of 3,776 fish were stripped, yielding 20.0 million ova, giving an average yield of 5,297 ova per fish.

Of the 231 active Atlantic salmon seawater cage sites in 2020, nine were certified as organic, producing 12,528 tonnes.

Escapes

There were five incidents involving the loss of 204,901 fish from seawater Atlantic salmon sites in 2020. There were 13 additional incidents reported where the companies confirmed there was no loss of fish.
