Scottish shellfish farm production survey 2016

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 2016, 180 sites produced shellfish for sale, an increase of 5% since 2015.

Table 3: Authorised and active businesses 2007-2016.

Table 4: Active and producing farm sites by region 2016.

Active = farms in a production growing cycle which may contain stock or be fallow.
Producing = placing on the market for the table and 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 2016 (number producing given in brackets) and number of producing businesses by region/species.

There were five Several Orders in place for scallop fisheries in 2016 ( see Fig. 2). Three 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.

a) Production for the table

b) Production for on-growing to other producers

c) No production, actively on-growing or fallow

Table 6: Business production levels by species 2016.

Business production levels by species are shown in Table 6. There were 15 businesses producing more than 100 tonnes of mussels, a decrease of four businesses since 2015. Out of these 15 companies, 11 produced more than 200 tonnes. These 11 companies produced 79% of the total mussel production in Scotland. There were six businesses that produced more than 200,000 Pacific oysters. The production from these businesses accounted for 78% of the Scottish total.
