Scallop dredging is a term used to describe the use of dredges which are towed along the seabed behind a vessel to catch scallops. The catch may include some fish and other shellfish species.

This is an introduction to the legislation covering scallop dredging in the Cornwall IFCA district .  If you would like to discuss any of the legislation below please contact us .

Within the  Cornwall IFCA district  you must comply with three layers of legislation.

European fishery rules: These are applied to the EU member states and cover a wide range of subjects including minimum fish sizes, fishing methods and gear, fish quotas, logbooks and landing declarations, vessel monitoring systems etc. The rules can all be found within a publication known as the Blue Book which can be viewed on the Marine Management Organisation’s website.


National rules: In addition to EU regulations, there is national legislation applied to fisheries and fishing activities.  These can also be found in the  Blue Book
 

Cornwall IFCA byelaws:  Locally, there are further fishing restrictions applied under Byelaws made by Cornwall IFCA for managing fisheries within its district.  The byelaws which may apply to a particular fishing method are listed below.
