Executive Summary

The tables below summarise the results from the 2014 fish farms annual production survey.

Rainbow Trout ( Oncorhynchus mykiss)

2013 2014
Total production (tonnes) 5,611 5,882
Production for the table (tonnes) 5,001 5,328
Production for restocking (tonnes) 610 554
Number of staff employed 110 113
Mean productivity (tonnes/person) 51.0 52.1
Number of ova laid down to hatch (millions) 9.9 10.0
Number of ova imported (millions) 9.3 10.4

In 2014, the production of rainbow trout increased by 271 tonnes. Employment increased by three staff and mean productivity increased to 52.1 tonnes per person. The number of ova laid down to hatch increased by 0.1 million and the number of ova imported increased by 1.1 million.

Atlantic salmon ( Salmo salar)


2013 2014
Number of ova produced (millions) 56.9 33.5
Number of ova laid down to hatch (millions) 66.6 70.8
Number of ova exported (millions) 0.7 0
Number of ova imported (millions) 48.5 58.9
Number of smolts produced (millions) 40.5 45.0
Number of smolts put to sea (millions) 40.9 48.1
Number of staff employed 285 309
Mean productivity (000's smolts/person) 142.0 145.6

The production of ova decreased by 23.4 million in 2014 and the number of ova laid down to hatch increased by 4.2 million. No ova were exported in 2014 and the number of ova imported increased by 10.4 million from the 2013 figure. The number of smolts produced increased by 4.5 million. In 2014 the number of staff increased by 24 and mean productivity increased by 3.6 tonnes per person. Although it should be noted that there are uncertainties with 2013 staff and productivity figures due to consolidation within the industry that year.

Production fish

Production of pre-salmon (tonnes) 58,665 55,311
Production of salmon (tonnes) 57,073 76,305
Mean fish weight 0-year (kg) - 2.5
Mean fish weight grilse (kg) 4.9 5.2

Mean fish weight salmon (kg) 5.1 5.6
Number of staff employed 1,180 1,325
Mean productivity tonnes/person 138.3 135.1

Production tonnage increased by 15,788 tonnes with an increase in the mean harvest weight of grilse and salmon but a decrease in the mean weight of pre-salmon. Staff numbers increased by 145 and mean productivity decreased to 135.1 tonnes per person.

Smolt survival (percentage harvested)

Survival (%) Years 0+1 Year 2 Total
2011 input year class 50.6 26.4 77.0
2012 input year class 52.0 33.4 85.4

The smolt survival rate for the 2012 input year class increased to 85.4%.

Other Species

Including Arctic charr ( Salvelinus alpinus); brown/sea trout ( Salmo trutta); cod ( Gadus morhua) ; halibut ( Hippoglossus hippoglossus) ; lumpsucker ( Cyclopterus lumpus) and several species of wrasse (Labridae)

2013 2014
Total production (tonnes) 100 a 119 a
Number of staff employed (full-time) 29 29
(part-time) 21 20
Number of ova laid down to hatch (millions) 7.7 b 17.8
Number of ova imported (millions) 0 c 1.1

Some figures are excluded from this report as providing them would reveal production information from individual companies.
a Excluding cod production.
b Excluding halibut ova laid down to hatch.
c Excluding halibut ova imported.

In 2014, the production of other species increased by 19 tonnes from the 2013 total. Overall, employment decreased by one person in 2014. There was a marked increase in the number of ova laid down to hatch although the complete 2013 figure for ova cannot be shown without revealing the information of an individual company.
