Scottish Fish Farm Production Survey 2015

3. Atlantic Salmon - Production

Production

Production survey information was collected from all 16 companies actively involved in Atlantic salmon production, farming 254 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 2015 was 171,722 tonnes, a decrease of 7,300 tonnes (4.1%) on the 2014 total. Production remained high as the 2015 total is the second highest level of production recorded in Scotland.

In 2013, the last year for which survival can be calculated, the survival rate from smolt input to harvest decreased to 76.3%. Of the 2014 year class, 50.6% of the input has been harvested, 0.4% higher than the average harvest of fish one year after input in the 2013 year class. In 2015, the harvest of fish from the 2015 input was 0.5%, this was a decrease compared with the proportion of fish harvested from the same year class in 2014.

The total number of smolts put to sea in 2015 was 45.5 million. This smolt input comprised S1s (49.6%), S½s (50.3%) and a small number of S1½s (>0.1%). Four percent of the smolts stocked to Scottish salmon farms were sourced from outwith Scotland, 2% of which came from sources outwith Great Britain. This was a decrease of 2% compared with the proportion observed in 2014.

* 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 2015, the total number of staff employed in salmon production was 1,363, an increase of 38 compared with 2014. 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 135.1 to 126.0 tonnes produced per person.

Production Methods

Method	Number of sites			Total capacity (000s cubic metres)			Production (tonnes)

Seawater cages	253	257	250	19,064	19,481	20,338	163,200	179,022	171,543
For cage sites: ratio of production (kg) to cage capacity (m 3)							8.6	9.2	8.4

In 2015, the majority of fish were produced in seawater cages. There were 179 tonnes of production from seawater tank sites in 2015. 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 fin fish or salmon broodstock.

Sea cage capacity increased by 857 m ³ during 2015 and the number of sea cage sites in production decreased by seven. Production efficiency in sea cages, measured as the ratio of fish weight in kilograms produced per cubic metre, decreased to 8.4 kg/m ³. In cage sites, the ratio of production (expressed in kilograms) to cage capacity (expressed in cubic metres) was 8.6, 9.2 and 8.4 in 2013, 2014 and 2015 respectively.

* Includes farms stocked but having no production.

In 2015, the number of sites with no production decreased by two whilst the number producing 1 to 500 tonnes decreased by six. The number of sites producing over 500 tonnes increased by two, continuing the trend towards production in larger sites with an increase of five in the number of sites producing over 1000 tonnes.

The greatest productivity of 130 tonnes per person was achieved in the companies producing over 2000 tonnes. The least productivity of 19 tonnes per person was from the companies producing between 101-200 tonnes. In comparison with 2014, the average company productivity decreased from 135 to 126 tonnes per person. Overall, production was dominated by six companies in 2015 which between them accounted for 99% of Scotland's farmed Atlantic salmon production.

The number of companies authorised and actively producing Atlantic salmon in 2015 was 10, a decrease of one from 2014. Six companies remained active and authorised, although not producing salmon for harvest in 2015. This continued the trend of Atlantic salmon production becoming concentrated within fewer companies. These 16 companies had 254 registered active sites, although not all these sites produced fish for harvest in 2015.

Of the 250 seawater cage sites recorded as being active in 2015, 47 sites were fallow for the entire year whilst 158 sites were fallow for a variable period. There were 45 sites that did not fallow in 2015. 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.

Broodstock Sites

Table 38: Number of sites holding Atlantic salmon broodstock during 2004-2015

Year	2004	2005	2006	2007	2008	2009	2010	2011	2012	2013	2014	2015
Broodstock sites	15	15	17	20	20	11	10	11	7	8	8	4

In 2015, the number of freshwater and seawater sites holding broodstock decreased to four. 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 1,875 fish were stripped, yielding 11.6 million ova, giving an average yield of 6,187 ova per fish.

Organic Production

Table 39: Organic production of Atlantic salmon during 2010-2015

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
2013	253	8	5,207
2014	257	8	3,588
2015	250	5	2,382

Of the 250 active Atlantic salmon seawater cage sites in 2015, five were certified as organic, producing 2,382 tonnes.

Escapes

There were five incidents involving the loss of 16,005 fish from seawater Atlantic salmon sites in 2015. There was one additional incident reported where the company confirmed there was no loss of fish.
