In 2016, the last year for which survival can be calculated, the survival rate from smolt input to harvest decreased to 76.6%. Of the 2017 year class, 47.3% of the input has been harvested, 12.6% lower than the average harvest of fish one year after input in the 2016 year class. In 2018, there was 0.2% fish harvested from the 2018 input. This was an increase compared with the proportion of fish harvested from the same year class in 2017.

The total number of smolts put to sea in 2018 was 45.4 million. This smolt input comprised S1s (52.3%) and S½s (47.7%). There were no S1½s put to sea in 2018 and no S2s have been put to sea since 2001. Four percent of the smolts stocked to Scottish salmon farms were sourced from outwith Scotland, 1% of which came from sources outwith GB. This was an increase of just over 1% compared with the proportion observed in 2017.

* 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 2018, the total number of staff employed in salmon production was 1,466, an increase of 77 compared with 2017. 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 136.6 to 106.4 tonnes produced per person.

In 2018, the majority of fish were produced in seawater cages. There were 35 tonnes of production from seawater tank sites in 2018. 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 814,000 m3 during 2018 and the number of sea cage sites in production decreased by five. Production efficiency in sea cages, measured as the ratio of fish weight in kilograms produced per cubic metre, decreased from 9.9kg/m3 in 2017 to 7.8 kg/m3 in 2018.

* Includes farms stocked but having no production.

In 2018, the number of sites with no production increased by seven and the number producing 1 to 500 tonnes increased by eight. The number of sites producing over 500 tonnes decreased by 20 but there continues to be a trend towards production in larger sites, with 82.0% of production being derived from sites producing over 1000 tonnes.

The greatest productivity of 109 tonnes per person was achieved in the companies producing over 2000 tonnes. The least productivity of 5 tonnes per person was from the companies producing between 0-100 tonnes. In comparison with 2017, the average company productivity decreased from 137 to 106 tonnes per person. Overall, production was dominated by six companies in 2018 which between them accounted for 99% of Scotland’s farmed Atlantic salmon production.

The number of companies authorised and actively producing Atlantic salmon in 2018 was eight, the same as in 2017. Four companies remained active and authorised, although not producing salmon for harvest in 2018. This continued the trend of Atlantic salmon production becoming concentrated within fewer companies. These 12 companies had 221 registered active sites, although not all these sites produced fish for harvest in 2018.

Of the 217 seawater cage sites recorded as being active in 2018, 32 sites were fallow for the entire year whilst 139 sites were fallow for a variable period. There were 46 sites that did not fallow in 2018. 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 2009-2018

In 2018, the number of freshwater and seawater sites holding broodstock remained the same with 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 2,114 fish were stripped, yielding 15.2 million ova, giving an average yield of 7,190 ova per fish.
