Black panthers transfer from Assam Zoo to Ambani owned zoo was through ‘barter policy': Assam Min Guwahati, Feb 23 (UNI) Assam Environment and Forest Minister Parimal Suklabaidya today said that the transfer of two black panthers from Assam state Zoo to Reliance-owned Greens Zoological Rescue and the Rehabilitation Kingdom at Jamnagar in Gujarat was done following government policy of 'barter system' of wildlife animals. “The black panthers were sent to Jamnagar zoo in exchange for their help to bring four Zebras from Israel. Animal exchange is part of zoo management. We frequently undertake animal exchange programme with various zoos in the country and with zoo outside the country,” Mr Suklabaidya said an issue which has triggered a controversy ahead of Assembly elections slated in April.
