"Ministry has not given permission for culling of wild animals," Dave said in reply to questions in the House.
States, he said, utilise the powers vested with them under Wildlife (Protection) Act, 1972 to mitigate human-wildlife conflict that include "scientific management of population by translocation of animals, fertility control of animals, construction of barriers, improvement of habitat, use of deterrents etc."
The minister said "declaration vermin for a limited period is a response only for dealing with overpopulation in some areas, outside forests."
Addressing concerns over 'Nilgai', Dave, who took over the charge of the ministry recently, said the number of wild animals has not gone down.
He also gave details as per which Bihar had proposed to get Nilgai and Wild Pig declared as vermin while Himachal Pradesh had sought the same status for Rhesus Macaque.
Other states which had given similar requests include Uttarakhand for Wild Pig, Maharashtra for Nilgai and wild pig and Gujarat for Nilgai.
