Eccentric Billy, who recently published his memoirs Fishing With Testacles, sold it to the then-called British Waterways in 2003.
BW then sold Makins Fishery on to Alan McDiarmid in 2008 for a reported £1 million.
The 58-acre Makins Fishery site includes 18 fish-stuffed lakes, tackle shop and café.
Plus there’s an adjoining caravan park catering for 35 touring caravan pitches, three high-specification holiday lodges, and a three-bedroom owners’ bungalow.
Day tickets start at £8 for adults for one rod and there are over 600 pegs to tackle.
Makins has produced carp to over 35lb, barbel to 12 lb, perch to 4lb 10oz and tench to over 7lb as well as huge match hauls.
Makins Fishery sale a “rare opportunity” Robert Smithson of estate agents Colliers International, said: “The current owners have done an excellent job in growing the business and establishing its reputation across the UK.
“This is a rare opportunity for a new owner to acquire an outstanding commercial coarse fishery business in an ideal and accessible trading location.”
“After developing an extremely successful fishery, Mr and Mrs McDiarmid diversified into the holiday market to ensure the business maintains a year-round range of income streams; which is proving to be worthwhile and offers substantial room for further growth.”
