Production

Production survey information was collected from all 21 companies actively involved in Atlantic salmon production, farming 257 active sites. This figure represents the entire industry operating in Scotland.

In 2011, the last year for which survival can be calculated, the survival rate from smolt input to harvest decreased to 77.0%. Of the 2012 year class, 52.0% of the input has been harvested, 1.4% higher than the average harvest of fish one year after input in the 2011 year class. In 2013, there was no harvest of fish from the 2013 smolt input. This was a decrease compared with the proportion of fish harvested from the same year class in 2012.

The total number of smolts put to sea in 2013 was 40.9 million. This smolt input comprised S1s (52.6%), S½s (47.1%) and a small number of S1½s (0.3%). Three percent of the smolts stocked to Scottish salmon farms were sourced from outwith Scotland. This was a decrease of 1% compared with the proportion observed in 2012.

* 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 2013, the total number of staff employed in salmon production was 1,086, an increase of 27 compared with 2012. 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 153.2 to 150.3 tonnes produced per person.

For cage sites: ratio of production (kg) to cage capacity (m 3) 9.2 9.1 8.6

The vast majority of fish were produced in seawater cages. There were 34 tonnes of production from seawater tank sites in 2013. This reflects the continued 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 fin fish or salmon broodstock.

Sea cage capacity increased by 1,175,000 m 3 during 2013 and the number of sea cage sites in production decreased by two. Production efficiency in sea cages, measured as the ratio of fish weight in kilograms produced per cubic metre, decreased to 8.6 kg/m 3.

* Includes farms stocked but having no production.

In 2013, the number of sites with no production dropped by three whilst the number producing 1 to 500 tonnes remained the same. The number of sites producing over 500 tonnes increased by three, continuing the trend towards production in larger sites.

In 2013, the greatest productivity of 247 tonnes per person was achieved in the companies producing 401-700 tonnes. The least productivity of two tonnes per person was from the companies producing the smallest tonnages. In comparison with 2012, the average company productivity decreased from 153 to 150 tonnes per person. Overall, production was dominated by seven companies in 2013 which between them accounted for over 98% of Scotland's farmed Atlantic salmon production.

The number of companies authorised and actively producing Atlantic salmon in 2013 was 15, a decrease of one from 2012. Six companies remained active and authorised, although not producing salmon for harvest in 2013. This continued the trend of Atlantic salmon production becoming concentrated within fewer companies. These 21 companies had 257 registered active sites, although not all these sites produced fish for harvest in 2013.

Of the 257 seawater cage sites recorded as being active in 2013, 43 farms were fallow for the entire year whilst 163 farms were fallow for a variable period. There were 51 sites that did not fallow in 2013.

Broodstock Sites

In 2013, the number of freshwater and seawater sites holding broodstock increased to eight. 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 5,683 fish were stripped, yielding 56.9 million ova, giving an average yield of 10,021 ova per fish.
