Scottish Shellfish Farm Production Survey 2014
This report is based on the returns of an annual survey questionnaire sent to all active authorised shellfish farming businesses in Scotland.
This document is part of a collection
The survey indicates that the shellfish species cultivated in Scottish waters in 2014 were:
|Pacific oyster:||Crassostrea gigas|
|Native oyster:||Ostrea edulis|
|Queen scallop:||Aequipecten opercularis|
Production was dominated by mussel and Pacific oyster, although small quantities of scallop, queen scallop (queen) and native oyster were also produced. The 2014 production data for each species by region are given in Table 1.

Table production by species is illustrated in Figure 1 ( see page 4), while trends in production for the table market and on-growing in Scotland are presented in Table 2.

Mussel production, for the table, increased by 14% in 2014 ( see figure 1) to 7,683 tonnes. This is the highest level of mussel production ever recorded in Scotland. The greatest contribution in regional mussel production was from Shetland, accounting for 5,919 tonnes or 77% of Scotland's total. Pacific oyster production increased by 79% from 2013. Following a drop in production in 2013, production has returned to a similar level as seen in previous years. This is mainly due to one of the largest pacific oyster producers developing new markets domestically and outwith Great Britain. The Strathclyde region produced 58% of Scotland's farmed Pacific oysters. Queen scallop production fell by 45% since 2013, a contributing factor was reported as poor spat settlement, while the production of farmed scallops increased by 20%. Both these sectors continue to target small niche markets. Production of native oysters decreased by 7% from 2013. Native oyster production accounts for a small percentage of total oyster production, however, demand for this species continues to be high.
FIGURE 1 TABLE PRODUCTION BY SPECIES 2005-2014.
Prices of farmed shellfish fluctuated throughout the year. Their value at first sale was estimated from the following figures (supplied by industry these vary with demand, level of production and geographical area of origin). The average price of Pacific oyster was £0.33 per shell; native oyster, £0.60 per shell; scallop, £1.29 per shell; queen scallop, £0.15 per shell and mussels £1200 per tonne. The value of the table trade is estimated from the production figures shown in Table 1 ( see page 2).
Mussel: £9.2 million
Pacific oyster: £1.1 million
Native oyster: £0.15 million
Scallop: £0.06 million
Queen: £0.003 million
The 2014 total value, at first sale for all species, was estimated at approximately £10.5 million, increase from £8.9 million in 2013.
