Stock status

4 of 5
High risk

The fishery for common whelk Buccinum undatum in Shetland inshore waters was scored as high risk.  This is because LPUE is below the long term average in the most recent assessment by the Shetland Shellfish Management Association (SSMO) and species is generally considered vulnerable to overfishing.

Management

3 of 5
Moderate risk

The management of common whelk up to the six mile limit has been scored as moderate risk.  There is a suite of management controls that are implemented for the whole creel fishery but there are no restrictions on buckie pots.  There is a MLS for common whelk.  The enforcement of management controls is done via logbook data and occasional patrols.

Bycatch

1 of 5
Very low risk

The bycatch risk of this fishery has been scored as low risk. This is because whilst discarding of common whelks, other gastropods and crustaceans occurs, these are released alive on hauling and survival rates are believed to be high.  Catch of protected, endangered and threatened species is minimal.  “Ghost fishing” by lost pots is not considered to be a problem.

Habitat

2 of 5
Low risk

The habitat impact of this fishery has been scored as low risk. The impact on the seabed is negligible but pots could potentially cause some abrasion to the sea floor during hauling or in particularly rough weather.
