Fishermen in Monmouthshire have fished using lave nets in the Severn Estuary since the 17th century.
This is some local history by Celt Roberts of Talsarnau, where the tradition was practised until recently: "Evan Jones (1859–1928) was noted for catching plaice on the shore.
He used to swim with one arm while holding a trident in the other, and often obtained a good catch.
His grandson Derwyn Evans worked for some years in the 1950s on Talsarnau beach cutting turf and travelling far to make lawns for bowling and tennis, and to such places as the plantation for Wembley.
Commercial fishing in Wales employs approximately 600 people full-time and was valued at £39 million in 2021.
