Abstract
The present study was carried out on the diversity of fish under the genus Garra from the Kaladan River and its tributaries of Mizoram, northeast India. The study reported the occurrence of seven species viz. Garra flavatra, G. cf. koladynensis, G. cf. matensis, G. nigricolis, G. rakhinica, G. manipurensis and G. khawbungi. Key to Garra species from Kaladan River drainage of Mizoram and their brief descriptions are given.
Highlights
The genus Garra Hamilton-Buchanan has been reviewed by Menon,[1] who recognized 37 species
Species belonging to the genus Garra have been recorded from different locations of Mizoram by different authors including the description of new species.[5,6,7,8,9]
Garra flavatra and G. manipurensis comes under vulnerable category under IUCN criteria and accounts for 28.6% each of the overall Garra species collected
Summary
The genus Garra Hamilton-Buchanan has been reviewed by Menon,[1] who recognized 37 species. Seven species under the genus Garra have been reported from southern Myanmar.[2] The major revision of the Garra species have been carried out by Menon[1] and Getahun.[3] The genus is widely distributed in southern China, south east Asia, India, middle east to northern and central Africa and comprises a total of 60 species out of which 40 species are from Asia.[3] Kotellat reported the occurrence of 64 Garra species.[4] recent works on Garra by Nebeshwar and Vishwanath highlighted the distribution of at least 79 species in China, South East Asia, India and Sri Lanka.[5] The possession of suctorial disc on the ventral surface of the head, just behind the mouth is an important character of the genus.[5] Most of the Garra species inhabit rapid running waters and adapt to the substratum by means of horizontally placed paired fins called the pectorals.[1]. Species belonging to the genus Garra have been recorded from different locations of Mizoram by different authors including the description of new species.[5,6,7,8,9] The present study aim to highlight a comprehensive report of Garra species from the Kaladan drainage of Mizoram, their distribution and conservation status
