Tourism companies operating in Tanzania will, as of next month, have to bid for the right to hunt in designated areas through a new online auction system.
The move is aimed at preventing corruption in this lucrative sector of the travel industry.
Tanzania Wildlife Management Authority says 26 hunting blocks will be made, with a maximum of five blocks allowed for any company.
Most of these are in the Unesco-listed Selous Game Reserve, known for its elephants, lions, zebras and giraffes.
Tourism last year contributed $2.4bn (£1.9bn) to the Tanzanian economy, and almost 1.5 million people visited the country which counts beaches, wildlife safaris and Mount Kilimanjaro among its attractions.
