Scallops Harvested within Classified production areas:

All Scallops harvested within classified production areas are classified as B unless harvested within classified production areas where all other mollusc shellfish are classified of being class A where such scallops may be classified as A.

Notes

Note 1 Seasonal classifications

Where the data shows a clear seasonal trend over a number of seasons, different classification categories apply for different seasons. Details, where applicable, are given in column VI above.

Note 2 Preliminary classifications

Classifications are described as preliminary when an area is being classified for the first time or after a period in suspension. The term may also be used where an incomplete dataset of results was to hand.

Note 3 Dormant Classifications

Fishery  has been dormant for at least 12 months, and limited monitoring data is available, or industry has decided cease production for at least a 12-month period. Sites that remain dormant are in danger of their Classification becoming lapsed due to a lack of monitoring data.  Producers should contact their local SFPA office if intending to reactivate a dormant classification in order that monthly classification monitoring sampling may resume.

Note 4 Short Term Classification

Where there are clear seasonal patterns to commercial activity in class A or B areas, in consultation with and enforced by local fishery regulations, monitoring may be considered for a reduced period of the year. This should start at least one month prior to the harvesting season for class A areas and two months prior to the season for class B areas and then continue throughout the season in prior agreement with the SFPA. Where it is intended to fish a short-term classification the SFPA should be contacted in writing in advance of fishing to seek approval to begin.
