Nets are used widely throughout the Cornwall IFCA district. There are many types of netting activity and a great deal of legislation which defines their use and the fish that can be kept. Different netting methods can be used to fish selectively for certain species but there are numerous restrictions on catch, mesh size, construction and protected areas. If you would like to discuss any of the legislation 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.
