There is a MSC-certifiedMSC Certified:

fishery on the giant Ezo scallop in Japan and since 2015 also in China. The shells are caught with [bottom otter trawls] or collected by divers (in China). Part of the brood is collected by hanging nets or ropes in the water where the larvae can attach themselves to.

Final assessment
Explanation assessment

Scallops are exclusively hand-picked in Norway. Although biological and population data lacks, it is assumed on the basis of other sources that the stock is stable and the fishery on scallops is sustainable.

The diving and hand-picking of scallops is a very selective way of fishing that doesn’t damage the environment. It is also good for the quality of the scallops.

The management in this area is largely effective.

Final assessment
Explanation assessment

The stock of scallops strongly varies in season and area. The prediction for the recruitement is hard and stock fluctuations are unpredictable. In general, there is no clear and accurate picture of the fishery in this area.

The diving and hand-picking of scallops is a very selective way of fishing that doesn’t damage the seabed. It is also good for the quality of the scallops.

There is no specific [management plan] and there are no quotas determined. The management is done at a national level. There are however plans for an EU-wide management for these kind of coastal-water fisheries.

Final assessment
Explanation assessment

The scallop is reasonably vulnerable to [fishing pressure]. The [stocks] of scallop in the United Kingdom, Ireland and France have been overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. 
in the past decades. Because the fishing pressure has been reduced and the species is now also farmed, the stock could increase, but there is not enough data on this.

Fishing with [dredges] can have [bycatch] of endangered ray and shark species. Moreover, there is a lot of [bycatch] of invertebrates. There are indications that dredges permamently damage the ecosystem of the seabed.

There is a managementplan for the fishery with dredges on scallops that limits the amount of dredges per ship and the amount of days at sea. This is reasonably effective.

General

Scallop

The most well known species of scallop is the great scallop, also known as king scallop or st. James shell (Pecten Maximus). This is the largest European scallop and can reach a length of 17 cm. The shell is white, brown, or pink. It is found from Norway to Portugal.

Most scallops in the shops are sold without the shell. These are often different species like the  Atlantic deep-sea scallop (Placopecten magellanicus), Patagonian scallop (Zygochlamys patagonica) or Yesso scallop (Patinopecten yessoensis).
