Description
Summary:The Golden mahseer Tor putitora is one of the most important sport fish even its endangered status due to its declining population. The length-weight relationship and the condition factor for T putitora (N=150) from four different geographical regions in eastern and western Himalayas were studied. Fish sampling took place from December 2009 to March 2011. The b (slope) values obtained ranged from 2.69-3.10. However, no significant deviation was observed from the isometric value (b3) therefore, population from all four locations followed isometric growth pattern. The length-weight regression equation obtained for Bhalokpong, Arunachal Pradesh was Log W=-5.276+3.108Log L; for Anji, J&K was Log W=-4.633+2.811Log; for Basoli, J&K was Log W=-4.315+2.690Log L and for Jogindernagar, eastern Himalayas in Jia bhoreli river was in better condition in comparison to western Himalayas. Among the western Himalayan region, the population of Ravi river was in poor condition.
