4. Other Species
The Scottish aquaculture industry has continued to farm other species of fish during 2019. The production of brown/sea trout (Salmo trutta) showed an increase, with the majority of production being for the angling restocking market. In 2019 there was production of halibut (Hippoglossus hippoglossus) but the figure cannot be published without revealing the production from an individual company. Lumpsucker (Cyclopterus lumpus) and several species of wrasse (Labridae) were also produced in 2019. The production of lumpsucker and wrasse are targeted at the marine Atlantic salmon industry where they are used as a biological control for parasites.

Production of Cleaner fish
|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.

# During 2019 there was trade of small halibut but figures cannot be shown without revealing the figure for an individual company.
There was also a small amount of production of brook charr (Salvelinus fontinalis) and tiger trout (Salmo trutta x Salvelinus fontinalis ). 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 20 sites recorded as producing other species in 2019, no organic production was reported.
There were no reported escapes from sites rearing other species during 2019.
