Annual Fish Farm Production Survey 2012
3. ATLANTIC SALMON - PRODUCTION
Production
Production survey information was collected from all 22 companies actively involved in Atlantic salmon production, farming 257 active sites. This figure represents the entire industry operating in Scotland.

*industry estimate of projected tonnage based on stocks currently being on-grown
The total production of Atlantic salmon during 2012 was 162,223 tonnes, an increase of 4,205 tonnes (2.7%) on the 2011 production.
Escapes
There were three incidents involving the loss of a total of 34,343 fish from seawater Atlantic salmon sites in 2012.

In 2010, the last year for which survival can be calculated, the survival rate from smolt input to harvest was 82.8%. The 2010 year class displayed a lower survival rate than that noted in 2009.
Of the 2011 year class, 50.6% of the input has been harvested, 1.7% higher than the average harvest of fish one year after input in the 2010 year class. The average harvest weight decreased to 4.5 kg.
In 2012, the harvest of fish from the 2012 smolt input remained the same at 0.3%.

The total number of smolts put to sea in 2012 was 41.1 million. The smolt input comprised mainly S1 smolts (57.1%). The proportion of photoperiod adjusted fish (S½ smolts) input was 42.2% while a small amount (0.7%) of S1½ smolts were also put to sea in 2012. Four percent of smolts input into Scottish salmon farms were sourced from outwith Scotland. This is the same proportion observed in 2011.

* 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.

The total number of staff employed in salmon production in 2012 was 1,059, an increase of 46 compared with 2011. The staffing figures collected refer specifically to the production of salmon and do not include figures for staff involved with processing or marketing activities. Productivity decreased from 156.0 to 153.2 tonnes production per person.

For cage sites: ratio of production (kg) to cage capacity (m 3) | 9.1 | 9.2 | 9.1 |
The vast majority of the fish were produced in seawater cages. There were 64 tonnes of production from seawater tank sites in 2012. This reflects the continued high installation and running costs incurred in operating seawater tank systems. Most seawater tank capacity has now been re-deployed for the production of other species or salmon broodstock.
Sea cage capacity increased by 737,000 m 3 during 2012. The number of sea cage sites in production increased by three. Production efficiency in cages, measured as the ratio of fish weight in kilograms produced per cubic metre decreased to 9.1 kg/m 3 in 2012. In cage sites, the ratio of production (expressed in kilograms) to cage capacity (expressed in cubic metres) was 9.1, 9.2 and 9.1 in 2010, 2011 and 2012 respectively.

In 2012, there was a decrease of 11 in the number of sites producing 1 to 500 tonnes and an increase of five in those sites producing over 500 tonnes. This shows a continuing trend towards production in larger sites.

The greatest productivity (213 tonnes per person) was achieved in the companies having a production between 1001-2,000 tonnes and the least (six tonnes per person) in the companies producing the smallest tonnages. In comparison with 2011, the average company productivity decreased from 156 to 153 tonnes per person.
Overall, production was dominated by eight companies in 2012 which between them accounted for over 98% of Scotland's salmon production.

The number of companies authorised and actively producing salmon in 2012 was 16, a decrease of five on the 2011 figure. Six companies remained active and authorised, although not producing salmon for harvest in 2012. This continued the trend of salmon production being concentrated within fewer companies. These 22 companies have 257 registered active sites, although not all active sites may have produced fish for harvest in 2012.

Of the 255 seawater cage sites recorded as being active in 2012, 160 farms were fallow for a variable period, whilst 37 farms were fallow for the whole of 2012. The normal production cycle in seawater varies in length between 18 months and two years and a fallow period at the end of production can break the cycle of disease or parasitic infections. There were 58 sites that had no fallow period in 2012.
Broodstock Sites

Year | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 | 2007 | 2008 | 2009 | 2010 | 2011 | 2012 |
---|---|---|---|---|---|---|---|---|---|---|---|---|
Broodstock sites | 15 | 19 | 20 | 15 | 15 | 17 | 20 | 20 | 11 | 10 | 11 | 7 |
In 2012, the number of freshwater and seawater sites holding broodstock decreased to seven. 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 6,042 fish were stripped, yielding just over 90 million ova, which can be calculated to show an average ova yield per fish of 14,896.
Organic Production

Year | Number of active cage sites | Number of cage sites certified as organic | Production (tonnes) |
---|---|---|---|
2010 | 247 | 14 | 6,122 |
2011 | 252 | 10 | 3,104 |
2012 | 255 | 7 | 4,597 |
Of the 255 seawater cage sites recorded as being active in Atlantic salmon production in 2012, seven were certified as organic producing 4,597 tonnes. This is the third year that data on organic production has been reported.
