Scottish Fish Farm Production Survey 2013
4. OTHER SPECIES

4. OTHER SPECIES

The Scottish aquaculture industry has continued to farm other species of fish during 2013. 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, decreased and there was no production of Arctic charr, Salvelinus alpinus. There was production of cod, Gadus morhua, but this figure cannot be shown without revealing the production for an individual company. Several species of wrasse (Labridae) continued to be produced in 2013. The production of wrasse is targeted at the marine Atlantic salmon industry where they are used as a biological control for parasites.

Ova Laid Down to Hatch

Own broodstock Other GB broodstock Foreign ova
Brown trout/sea trout 658 0 0
Halibut 0
Wrasse spp. 7,090 0 0

‡ Ova were laid down to hatch in both categories but these data cannot be shown without revealing the figures for an individual company.

Trade in Small Fish

Table 43: Trade in small fish of other species in 2013

Species Bought (000's) Sold (000's)
Halibut 44 ~
Brown trout/sea trout 69 40
Wrasse spp. ~ 16

~ These data cannot be shown without revealing the figures for individual companies.

There was also a small amount of production of: brook charr, Salvelinus fontinalis; carp, Cyprinus carpio; Dover sole, Solea solea; haddock, Melanogrammus aeglefinus; sea bass, Dicentrarchus labrax; sheepshead minnow, Cyprinodon variegatus variegatus; tiger trout, Salmo trutta cross salvelinus fontinalis; tilapia, Tilapia Spp; turbot, Psetta maxima and whiting, Merlangius merlangus. 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 26 sites recorded as producing other species in 2012, no organic production was reported.

Escapes

There was one reported incident leading to an escape of 6,957 halibut from a site in 2013.
