Chilika buffalo is native to the Eastern coast of India and well adapted to the largest coastal brackish water lagoon of Asia, Chilika Lake. We present here a report on the Chilika buffalo breed emphasizing the conservational urgency based on unique biochemical and molecular evidence related to liver and kidney functions while comparing it with tropically adapted other water buffalo breeds (Bubalus bubalis) of India. It is found that the Chilika buffalo breed has a better ability to withstand a long dehydration period as evident from its better glomerular filtration and higher expression of the ion transport channel. Mitochondrial D-loop sequencing results have shown these buffaloes being closer to swamp-type buffaloes of Bangladesh and northeast India and represent a unique "hybrid zone" on the eastern coast of India. Conservation of such uniquely adapted germplasm is crucial owing to the current global trend, where the introduction of exotic breeds has negatively impact "sui-generis" germplasm and they require higher managerial resource consumption for maintaining higher productivity. Further, the introduction of unconventional fisheries activities has proved detrimental to the lagoon ecosystem, potentially causing more threat to the buffalo's population.
