Annual Fish Farm Production Survey 2012
Annual Fish Farm Production Survey 2012
4. OTHER SPECIES
The Scottish aquaculture industry has continued to farm other species during 2012. Brown trout ( Salmo trutta) production showed a decrease during the year with the majority of the production being for the restocking market. The production of Arctic charr ( Salvelinus alpinus) and halibut ( Hippoglossus hippoglossus) production also decreased. For the second consecutive year there was no cod ( Gadus morhua) prodution for the table market. However, 2012 saw an increase in the number of companies active in the culture of several species of wrasse ( Labridae). Employment provided by these sectors increased by three in 2012.

Company, Site and Production Data

| Species | No. of companies | No. of sites | 2009 Production tonnage | 2010 Production tonnage | 2011 Production tonnage | 2012 Production tonnage | 2013 Production tonnage* |
|---|---|---|---|---|---|---|---|
| Arctic charr | 1 | 1 | 1.5 | 1.5 | 1.5 | 0.2 | 0 |
| Brown trout/sea trout | 14 | 20 | 199 | 53 | 61 | 42 | 47 |
| Cod | 0 | 0 | 0.1 | 0.7 | 0 | 0 | 0 |
| Halibut | 2 | 4 | 189 | 139 | 83 | 73 | 63 |
| Wrasse | 5 | 5 | 0 | 0 | 0 | c | c |
*Industry estimates based on stocks currently being on-grown
c A small amount of wrasse production occurred and is estimated but it is not possible to summarise these data without potentially revealing the figure for individual companies.
Not all of this production is for the table market with the majority of brown trout production being for the angling restocking market. Wrasse production is targeted at the marine Atlantic salmon industry where they are used as a biological control for parasites.
Escapes
There were no reported escapes from sites rearing other species in 2012.
Ova Laid Down to Hatch

| Species | Source of ova laid down to hatch (000's) | ||
|---|---|---|---|
| Own broodstock | Other GB broodstock | Foreign ova | |
| Brown trout/sea trout | 527 | 0 | 0 |
| Halibut | 500 | 0 | 0 |
| Wrasse | 826 | 0 | d |
d A small number of companies laid down wrasse ova from foreign sources but it is not possible to summarise these data without potentially revealing the figure for individual companies.
Trade in Small Fish
Table 43: Trade in small fish of other species in 2012
| Species | Bought (000's) | Sold (000's) |
|---|---|---|
| Halibut | 33 | 13 |
| Brown trout/sea trout | 52 | 36 |
| Wrasse | 14 | e |
e A small number of companies sold wrasse but it is not possible to summarise these data without potentially revealing the figure for individual companies.
There were also sites stocked with brook charr ( Salvelinus fontinalis), carp ( Cyprinus carpio), lump sucker ( Cyclopterus lumpus), seabass ( Dicentrarchus labrax), sheepshead minnow ( Cyprinodon variegatus variegatus), tiger trout ( Salmo trutta cross salvelinus fontinalis), turbot ( Psetta maxima), tilapia ( Tilapia Spp) and zebrafish ( Danio rerio). There was production of brook charr, carp, sheepshead minnow, tiger trout 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 26 sites recorded as producing other species in 2012, no organic production was reported.
