Sharks are being serenaded with love songs to inspire them to mate.
Bloodnose and Lucy have not yet consummated their relationship
Experts at the Blackpool Sea Life Centre are going to play classical music into the tanks to ignite passions between the resident brown sharks.
The desperate measures have been introduced after elderly shark Bloodnose spurned the charms of teenage female Lucy despite meeting a year ago.
Music including Memory from Cats and Beethoven's Moonlight Sonata will be played over the open-topped tank.
Classical greats such as Mozart's Romanze and Puccini's Nessun Dorma will also be played.
The sharks will be played Beethoven's Moonlight Sonata
Tunes by Barry White have been rejected on the grounds that previous playings failed to give sharks loving feelings.
Recent studies by scientists at the Rowland Institute in Cambridge, Massachusetts, found fish could listen and process melodies in a similar way to humans.
Bloodnose, 20, was introduced to 15-year-old Lucy but the relationship has never been consummated.
Romance has also failed to blossom with either of Bloodnose's fellow sharks Charlie and Woodstock, also aged 15.
Display supervisor Carey Duckhouse said: "Hopefully they will mate and maybe this time next year we will be caring for six or seven little sharks."
