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.


3. Atlantic Salmon - Production

Production

Production survey information was collected from all 11 companies actively involved in Atlantic salmon production, farming 226 active sites. This figure represents the entire industry operating in Scotland.

In 2017, the last year for which survival can be calculated, the survival rate from smolt input to harvest decreased to 73.8%. Of the 2018 year class, 58.2% of the input has been harvested, 10.9% higher than the average harvest of fish one year after input in the 2017 year class. In 2019, 0.6% of the fish were harvested from the 2019 input. This was an increase compared with the proportion of fish harvested from the same year class in 2018.

The total number of smolts put to sea in 2019 was almost 53.0 million. This smolt input comprised S½s (46.3%) and S1s (53.7%). Two percent of the smolts stocked to Scottish salmon farms were sourced from outwith Scotland, less than 1% of which came from sources outwith GB. This was a decrease of 2% compared with the proportion observed in 2018.

* The survival of the 2008 smolt input in the South West is over 100% due to the practice of putting smolts to sea in one region and subsequently moving them to another sea water site in another region for harvest.

In 2019, the total number of staff employed in salmon production was 1,651, an increase of 185 compared with 2018. 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 increased from 106.4 to 123.5 tonnes produced per person.

In 2019, the majority of fish were produced in seawater cages. There were 28 tonnes of production from seawater tank sites in 2019. 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 1,706,000 m3 during 2019 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, increased from 7.8 kg/m3 in 2018 to 9.4 kg/m3 in 2019.

In 2019, the number of sites with no production decreased by 20 and the number producing 1 to 500 tonnes increased by two. The number of sites producing over 500 tonnes increased by 23 and the trend towards production in larger sites continued, with 87.1% of production being derived from sites producing over 1,000 tonnes.

The greatest productivity of 126 tonnes per person was achieved in the companies producing over 2,000 tonnes. The least productivity of 2 tonnes per person was from the companies producing between 0-100 tonnes. In comparison with 2018, the average company productivity increased from 106 to 124 tonnes per person. Overall, production was dominated by six companies in 2019 which between them accounted for 99% of Scotland’s farmed Atlantic salmon production.

The number of companies authorised and actively producing Atlantic salmon in 2019 was eight, the same number as in 2018. Three companies remained active and authorised, although not producing salmon for harvest in 2019. This continued the trend of Atlantic salmon production becoming concentrated within fewer companies. These 11 companies had 226 registered active sites, although not all these sites produced fish for harvest in 2019.

Of the 224 seawater cage sites recorded as being active in 2019, 37 sites were fallow for the entire year whilst 150 sites were fallow for a variable period. There were 37 sites that did not fallow in 2019. 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.
