Adopt An Animal’ Scheme was launched by Dy. CM Sushil   Kumar Modi at the Sanjay Gandhi Biological Park, on 20th   July 2012. This scheme is primarily aimed at raising  awareness about wildlife among people.
The zoo authorities will give the adopter an array of   privileges. “The animal adoption scheme is aimed at direct   bonding between people and wild animals and encourage  their conservation. The amount realised as adoption   charges would be utilised for the feed and upkeep of   animals. For   this, the adopter would get some privileges.   Their names would be displayed prominently to give them   recognition and to inspire more and more people to become a part of this scheme,” said the zoo director. The adopters would get a certificate of animal adoption along with zoo souvenir, free zoo publications, passes for the orientation in zoo, free entry passes and permission to host get-together on the zoo premises besides other facilities.

The name of the adopter(s) would also be included in the annual report of the zoo and displayed near the enclosure on a board. “Interested individuals/ families/institutions would have to deposit the entire adoption amount through cheque/ bankers’ cheque/demand draft at the zoo director’s office. The amount would be deposited in the treasury like other revenue receipts of the zoo and the details would be maintained separately
On the first day itself, twelve organisations, namely, Life insurance corporation of india, Bank of Baroda, State Bank of India, Union Bank, Patna Dairy project, Central Bank of India, Canara Bank, Security and Intelligence Services of india, Bihar State Bridge Construction Corporation, Bihar State Road Construction corporation Limited, Shree cements from Kolkata and Tirhut milk union, Muzaffarpur, adopted several animals and birds enclosures.
After launching the scheme, Dy. CM, Shri Sushil Kumar Modi said that such programme is running in several zoos across the country but nowhere, it has evoked such a response in the beginning itself. He thanked the people of Bihar and the organizations for their enthusiasm.

Except for Bihar State State Bridge Construction corporation which adopted a lioness, Saraswati, for three years, all other animals were adopted for a year only. The Takers were given a memento and a certificate by the zoo authority.

Under the animal adoption scheme, individuals or families can adopt animals from six months to one year. Commercial firms can adopt animals from one to five years. The enclosures can also be adopted for one to three years and the entire zoo at Rs 25,000 for a day.
