Scottish shellfish farm production survey 2017
This report is based on the returns of an annual survey questionnaire sent to all active authorised shellfish farming businesses in Scotland.
Sites and Businesses
The numbers of authorised, active businesses and sites in operation are presented in Tables 3 and 4. There are many sites that held stock not yet ready for market, others were fallow, and some were located in remote areas where cost-effective production and marketing of shellfish proved difficult.
Historically, production data have been collected by business. However, since 2002, data have been collected for both business and site, enabling the provision of more accurate site information. In 2017, 176 sites produced shellfish for sale, a decrease of 2% since 2016.

Active = Farms in a production growing cycle which may contain stock or be fallow.
Producing = Placing on the market for the table and/or on-growing.
NB: A business may produce more than one species and in more than one region.
Figure 2 - Regional Distribution of Active Shellfish Sites in 2017 (Number Producing Given in Brackets) and Number of Producing Businesses by Region/Species.
There were six Several Orders in place for scallop fisheries in 2017 ( see Fig. 2). Four of these Orders are in the Highland region and two in Strathclyde.
Table 5 depicts the number of businesses by region and by species: A) in table production, B) in on-growing production and C) showing no production. Many businesses cultivate more than one species on site, a practice made possible by similar cultivation techniques. For example, scallop can be grown together with queen, Pacific oyster with native oyster, and mussel with Pacific oyster.

Business production levels by species are shown in Table 6. There were 18 businesses producing more than 100 tonnes of mussels, an increase of three businesses since 2016. Out of these 18 businesses, 11 produced more than 200 tonnes. These 11 businesses produced 79% of the total mussel production in Scotland. There were five businesses that produced more than 200,000 Pacific oysters. The production from these businesses accounted for 77% of the Scottish Pacific oyster total.
