4. Other Species
The Scottish aquaculture industry has continued to farm other species of fish during 2016. The production of brown trout ( Salmo trutta) showed a small decrease, with the majority of the production being for the angling restocking market. Production of halibut ( Hippoglossus hippoglossus) increased while there was no Arctic charr ( Salvelinus alpinus) or cod ( Gadus morhua) production during 2016. Lumpsucker ( Cyclopterus lumpus) and several species of wrasse (Labridae) were also produced in 2016. The production of lumpsucker and wrasse are targeted at the marine Atlantic salmon industry where they are used as a biological control for parasites.
Company, Site and Production Data
Table 40: Number of companies and sites producing other species in 2016, annual production of other species (tonnes) during 2013-2016 and estimated production in 2017
|Species||No. of companies||No. of sites||2013 Production tonnage||2014 Production tonnage||2015 Production tonnage||2016 Production tonnage||2017 Production tonnage*|
|Brown trout/ sea trout||12||15||44||48||42||41||92|
* Industry estimates based on stocks currently being on-grown.
t Production occurred but this cannot be shown without revealing the figure for an individual company.
Table 41: Number of staff employed in farming other species during 2007-2016
In 2016, the overall number of staff employed in the production of other species increased by 13.
Production of Cleaner fish
Table 42: Number (000's) of cleaner fish produced during 2015-2016
|Species||Number of fish produced (000's)|
In recent years lumpsucker and wrasse spp. have been produced for use as a biological control for parasites in the marine Atlantic salmon industry. Data on the number of fish produced has only been collected since 2015. As data for future years is collected it will show trends in cleaner fish production.
Ova Laid Down to Hatch

Trade in Small Fish

|Species||Bought (000's)||Sold (000's)|
|Brown trout/sea trout||49||17|
There was also a small amount of production of: brook charr ( Salvelinus fontinalis); sheepshead minnow ( Cyprinodon variegatus variegatus); tiger trout ( Salmo trutta x Salvelinus fontinalis) and turbot ( Scophthalmus maximus). However, due to the small number of companies in production, it is not possible to summarise these data without revealing the production of individual companies.
Of the 30 sites recorded as producing other species in 2016, no organic production was reported.
There were no reported escapes from sites rearing other species during 2016.
