King's Lynn Angling Association, the biggest club in the Fens, today revealed bylaw changes in a bid to tackle fish being removed in numbers for food.
It's changed its bylaws to make it clear no fish are to removed from the waters it controls, which include parts of the Great Ouse, River Wissey, Little Ouse, Middle Level Drain, Cut Off Channel and Relief Channel.
The wording on permits and day tickets has been changed, while signs have been put up at club venues.
Officials believe the move allows a private prosecution to be taken out against anyone caught removing fish. It comes after fish were removed in numbers from Lynn AA waters.
Livebaiting is still allowed, provided they are used on the water where they have been caught.
