Scottish Fish Farm Production Survey 2014

3. Atlantic Salmon - Production

Production

Production survey information was collected from all 18 companies actively involved in Atlantic salmon production, farming 260 active sites. This figure represents the entire industry operating in Scotland.

In 2012, the last year for which survival can be calculated, the survival rate from smolt input to harvest increased to 85.4%. Of the 2013 year class, 49.6% of the input has been harvested, 2.1% lower than the average harvest of fish one year after input in the 2012 year class. In 2014, the harvest of fish from the 2014 input was 0.6%, this was an increase compared with the proportion of fish harvested from the same year class in 2013.

The total number of smolts put to sea in 2014 was 48.1 million. This smolt input comprised S1s (50.3%), S½s (49.4%) and a small number of S1½s (0.3%). Six percent of the smolts stocked to Scottish salmon farms were sourced from outwith Scotland, 4% of which came from sources outwith Great Britain. This was an increase of 3% compared with the proportion observed in 2013.

* 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 2014, the total number of staff employed in salmon production was 1,325, an increase of 145 compared with 2013. 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 138.3 to 135.1 tonnes produced per person.

Production Methods

Table 32: Production methods, capacity, tonnage and average stocking densities (kg/m ³) during 2012-2014

Method	Number of sites			Total capacity (000's cubic metres)			Production (tonnes)
	2012	2013	2014	2012	2013	2014	2012	2013	2014
Seawater tanks	2	4	3	5.9	6.0	6.1	64	34	0
Seawater cages	255	253	257	17,889	19,064	19,481	162,159	163,200	179,022
For cage sites: ratio of production (kg) to cage capacity (m 3)							9.1	8.6	9.2

In 2014, all fish were produced in seawater cages and there was no production from seawater tank sites. 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 417,000 m ³ during 2014 and the number of sea cage sites in production increased by four. Production efficiency in sea cages, measured as the ratio of fish weight in kilograms produced per cubic metre, increased to 9.2 kg/m ³. In cage sites, the ratio of production (expressed in kilograms) to cage capacity (expressed in cubic metres) was 9.1, 8.6 and 9.2 in 2012, 2013 and 2014 respectively.

* Includes farms stocked but having no production.

In 2014, the number of sites with no production rose by five whilst the number producing 1 to 500 tonnes increased by two. Despite the number of sites producing over 500 tonnes decreasing by four, there was still a continuing the trend towards production in larger sites with an increase of three in the number of sites producing over 1000 tonnes.

The greatest productivity of 192 tonnes per person was achieved in the companies producing 1,001-2,000 tonnes. The least productivity of three tonnes per person was from the companies producing the smallest tonnages. In comparison with 2013, the average company productivity decreased from 138 to 135 tonnes per person. Overall, production was dominated by six companies in 2014 which between them accounted for 99% of Scotland's farmed Atlantic salmon production.

The number of companies authorised and actively producing Atlantic salmon in 2014 was 11, a decrease of four from 2013. Seven companies remained active and authorised, although not producing salmon for harvest in 2014. This continued the trend of Atlantic salmon production becoming concentrated within fewer companies. These 18 companies had 260 registered active sites, although not all these sites produced fish for harvest in 2014.

Of the 257 seawater cage sites recorded as being active in 2014, 51 sites were fallow for the entire year whilst 206 sites were fallow for a variable period. There were 48 sites that did not fallow in 2014. 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 2003-2014

Year	2003	2004	2005	2006	2007	2008	2009	2010	2011	2012	2013	2014
Broodstock sites	20	15	15	17	20	20	11	10	11	7	8	8

In 2014, the number of freshwater and seawater sites holding broodstock remained at 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 2,711 fish were stripped, yielding 33.5 million ova, giving an average yield of 12,357 ova per fish.

Organic Production

Table 39: Organic production of Atlantic salmon during 2010-2014

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

Of the 257 active Atlantic salmon seawater cage sites in 2014, eight were certified as organic, producing 3,588 tonnes. This is the fifth year that data on organic production has been reported.

Escapes

There were 10 incidents involving the loss of 184,613 fish from seawater Atlantic salmon sites in 2014. There were two additional incidents reported where the companies confirmed there was no loss of fish.
