Adrian Pinder of Bournemouth University in the UK and Dr Rajeev Raghavan of St Albert's College in Kochi have been studying the ecology, taxonomy and conservation status of 17 species of mahseer which populate rivers throughout south and southeast Asia since 2010."Comparing photographs over the internet opened a can of worms and confirmed that very little was known about all of the Mahseer species found throughout south and south East Asia," said Pinder.
