Scottish Fish Farm Production Survey 2014
This report is based on the returns of an annual survey questionnaire sent to all active authorised fish farming businesses in Scotland.
4. Other Species
The Scottish aquaculture industry has continued to farm other species of fish during 2014. The production of brown trout ( Salmo trutta) showed a small increase, with the majority of the production being for the angling restocking market. The production of halibut ( Hippoglossus hippoglossus) increased while there was no production of Arctic charr ( Salvelinus alpinus) during 2014. There was production of cod ( Gadus morhua) but this figure cannot be shown without revealing the production for an individual company. Lumpsucker ( Cyclopterus lumpus)and several species of wrasse (Labridae) were also produced in 2014. The production of lumpsucker and wrasse are targeted at the marine Atlantic salmon industry where they are used as a biological control for parasites.

| 2006 | 92 | 17 | 109 |

| 2013 | 29 | 21 | 50 |

In 2014, the overall number of staff employed in the production of other species decreased by one.
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 | 442 | 130 | 0 |
| Halibut | 5,000 | 0 | 1,000 |
| Lumpsucker | 0 | 1,064 | 120 |
| Wrasse spp. | 10,200 | 0 | 0 |
Trade in Small Fish
Table 43: Trade in small fish of other species in 2014
| Species | Bought (000's) | Sold (000's) |
|---|---|---|
| Halibut | 40 | 120 |
| Brown trout/sea trout | 89 | 107 |
| Lumpsucker | 14 | 47 |
| Wrasse spp. | <1 | 14 |
There was also a small amount of production of: brook charr ( Salvelinus fontinalis); carp ( Cyprinus carpio); sheepshead minnow ( Cyprinodon variegatus variegatus); tiger trout ( Salmo trutta) cross ( Salvelinus fontinalis); tilapia, ( Tilapia Spp.) 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.
Organic Production
Of the 29 sites recorded as producing other species in 2014, no organic production was reported.
Escapes
There were no reported escapes from sites rearing other species during 2014.
