Scottish fin fish farm sites operated by authorised aquaculture production businesses.

4. OTHER SPECIES
There has been a continued interest in the farming of other species. Brown trout ( Salmo trutta) production showed a small increase in 2011. The majority of the production was for the restocking market. The production of Arctic charr ( Salvelinus alpinus) remained the same whilst there was a decrease in halibut ( Hippoglossus hippoglossus) production. There were no Cod ( Gadus morhua) produced for the table market in 2011. Employment provided by these sectors has remained level.

*Industry estimates based on stocks currently being on-grown

Escapes
There were no reported escapes from sites rearing other species in 2011.

| Own broodstock | Other GB broodstock | Foreign ova | |
| Arctic charr | 60 | 0 | 0 |
| Cod | 30 | 0 | 0 |

Trade in Small Fish

| Species | Bought (000's) | Sold (000's) |
|---|---|---|
| Cod | 0 | 0 |
| Halibut | 71 | 53 |
| Brown trout/Sea trout | 43.8 | 175.3 |
There were also sites stocked with ballan wrasse ( Labrus bergylta), brook charr ( Salvelinus fontinalis), carp ( Cyprinus carpio), common sole ( Solea solea), haddock ( Melanogrammus aeglefinus), sheepshead minnow ( Cyprinodon variegatus variegatus), turbot ( Psetta maxima) and tilapia ( Tilapia Spp). There was production of brook charr, carp, common sole and tilapia but due to the small number of companies in production, it is not possible to summarise these data without revealing the production of individual companies.
Organic Production
Of the 34 sites recorded as producing other species in 2011, one brown trout/sea trout producer was certified as organic. It is not possible to detail this data without revealing the production of individual companies.
