Based on the habitat types, thirty species of cyprinids in nine streams located in the Western Ghat mountain ranges, hotspot of biodiversity have been classified into six guilds. Shallow pools (<60cm deep and velocities <30 cm/s) were preferred by juveniles and adults of big sized barbs such as Hypselobarbus micropogon, Tor khudree and Neolissochilus wynaadensis. Slow riffles (< 60 cm deep and velocities 30-59 cm/s) were preferredby juveniles of surface dwellers such as Barilius canarensis, B. gatensis, Devario aequipinnatus, Salmophasia boopis, Salmophasia acinaces and Chela labuca; bottom and substrate dwellers such as Garramullya and Garra stenorhynchus. Fast riffles (< 60 cm deep and velocities ≥ 60 cm/s) were preferred by the surface dwelling species and species of Garra. Almost all the cyprinid species preferred the medium pool (60-149 cmdeep and velocities <30 cm/s). Big sized barbs and torines (game fish) were confined to deep pools (≥150 cm deep). Among the nine streams raceway is identified in one stream (60-149cm deep and velocities ≥30 cm/s) which was preferred by juveniles and adults of Garra stenorhynchus and Barilius gatensis. Guild structures ofcyprinid species are consistent in almost all the streams. [ABSTRACT FROM AUTHOR] |
