The present study is aimed to document the movement and habitat use of golden mahseers (Tor putitora) inhabiting the Himalayan waters in India. A total of nine adult golden mahseers (two males and seven females) fitted with a VHF radio tag were monitored between pre-monsoon and post-monsoon periods. The individuals were found dispersed with the maximum recorded distance of 4231.23 and 6119.11 m in the Kosi and Kolhu rivers respectively. Home ranges for males (0.0245 sq. km) and larger individuals (0.0697 sq. km) exhibited released side fidelity, whereas females (0.361 sq. km) and smaller individuals (0.459 sq. km) moved long distances. The results of this study identify the movements and spatial ecology knowledge of golden mahseer to conserve fish habitats

Abstract


The present study is aimed to document the movement and habitat use of golden mahseers (Tor putitora) inhabiting the Himalayan waters in India. A total of nine adult golden mahseers (two males and seven females) fitted with a VHF radio tag were monitored between pre-monsoon and post-monsoon periods. The individuals were found dispersed with the maximum recorded distance of 4231.23 and 6119.11 m in the Kosi and Kolhu rivers respectively. Home ranges for males (0.0245 sq. km) and larger individuals (0.0697 sq. km) exhibited released side fidelity, whereas females (0.361 sq. km) and smaller individuals (0.459 sq. km) moved long distances. The results of this study identify the movements and spatial ecology knowledge of golden mahseer to conserve fish habitats
