The march was accompanied by around 100 taxis. The protest was organized by DK District Taximen and Maxicab Association, with other transport organisations.
The protesters later held a meeting in front of the Deputy Commissioner's office.
Addressing the gathering, former MLC and Mangaluru Taximen Association President Monappa Bhandary said the operation of Ola services were affecting the livelihood of taxi drivers.
He said that despite frequent pleas to the Deputy Commissioner and the Regional Transport Officer against the Ola cabs, no step had been taken so far.
Karnataka state tourist vehicle owners' association President K G Ravindra, said private companies were trying to monopolise the taxi service sector, putting taxi drivers to hardship.
Airport Taxi Drivers Association Secretary Radhakrishna Holla, Mangaluru Travel Owners' Association President Roshan Pinto, Taximen Association Secretary K Anand and Udupi Taximen Association secretary Ramesh Kotian were present.
