Fishing Byelaws

Freshwater Byelaws

Freshwater Fishing in Wales is subject to national and local byelaws, which govern when, where and how you can fish for various species; this is in order to protect the future of fisheries and to provide better fishing opportunities for you, the angler.

Angling byelaws apply to all rivers and lakes – whether they are owned by angling clubs, local authorities or private individuals. 

All angling bylaws in Wales can be found on the Natural Resources Wales (NRW) website HERE.

Please read these before you fish in Wales!

Migratory salmonid fish – Atlantic salmon and sea trout – there are new, specific bylaws which must be adhered to when fishing in Wales.

Sea fishing byelaws and size regulations: 

Sea anglers may take their catches home to eat in Wales – there are no minimum sizes or bag limits for the vast majority of sea species in Wales (apart from bass). This is due to a recent change in EU law, where minimum sizes no longer apply to fish captured during recreational fishing.

However Angling Trust, Fishing In Wales, Angling Cymru and the Welsh Federation of Sea Anglers (WFSA) have always supported minimum sizes – as a tool to conserve juvenile fish and improve sport for anglers. Therefore, we support voluntary size limits at a minimum size where the species has at least one chance to spawn before capture. Click the link below to see a list of WFSA recommended sea fish size limits for Wales: WFSA Minimum sizes

Sea bass restriction: Bass have a size limit of 42cm and a daily limit of 2 fish from 1 March to 30 November (catch and release the other 3 months)
