Fisheries are composed of one or more parts, each of which is entitled to receive an MSC certificate. These parts or “units” are defined by their target stock(s), fishing gear type(s) and if relevant vessel type(s), and the fishing fleets or groups of vessels.
When the term “Unit of Certification” is used for fishing units that are in assessment, it refers to the “Unit of Assessment” or “Unit of potential certification”.

Units of Certification & Certificate Information
Catch by Species
|Species||Reported Catch Year||Metric Tonnes|
|Atlantic scallop (Placopecten magellanicus)||2022||12,052|
Information is provided by an independent Conformity Assessment Body as live weight (the weight of species at the time of catch, before processing) and where a fishing season covers multiple years, the end year is given as the reported catch year. Additional information is available in the latest report, see the assessments page.
Eligibility, client groups and vessel lists
A fishery may choose to define the members of the fishery certificate. These members can be vessels or other client group members (e.g. companies that own vessels and/or companies that are named as eligible to handle certified product covered within the fishery certificate scope). Please refer to the fishery certificate statement on additional product specific eligibility criteria (e.g. product eligibility limitations, eligibility date, exclusive points of landing and the point where Chain of Custody certificate is required). Please consult the fishery Public Certification Report for product eligibility rationale.

About this Fishery
This fishery extends from Maine down to Cape Hatteras, North Carolina; and was certified in 2013. 348 vessels are involved, using New Bedford dredges.
The Atlantic sea scallop (Placopecten magellanicus) is a large scallop that commonly reaches 100 to 150mm shell height, with individuals larger than 200mm occasionally reported. Fecundity is high, with females producing 1-270 million eggs per individual, increasing rapidly with shell height. Spawning in US waters generally occurs as a single peak in late summer or early autumn (August to October).
The New Bedford scallop dredge is one of the sturdiest and heaviest in operation, and has changed very little since it was first introduced. Essentially it consists of a heavy metal frame and a steel mesh bag to retain the scallops. The lower side of the bag, that comes in contact with the seabed, and the rear portion of the top side, is constructed of a mesh of steel rings that allows small scallops, bycatch and bottom debris to escape, while the front section of the top of the bag is a panel of large-mesh twine netting though which fish can escape. Since 2005, the legal minimum ring size has been increased to 4 inches to increase yield-per-recruit, and the minimum twine top mesh increased to 10 inches to reduce fish bycatch.
