Reeves-Styles, from Swan Lane in Bromsgrove, was fined a total of £80.00 for the offences and ordered to pay costs of £15.00 and a surcharge of £34.00.
It comes after people were spotted fishing off of the Diglis Basin in October.
The Canal and Rivers Trust has stressed there should be no fishing at the city location and urged people to contact the authorities if they see fishing taking place.
