Length-weight relationship and condition factor of Barilius ngawa from head water of Thoubal River, Manipur, India

Abstract

The present study aims to describe the length-weight relationship and condition factor of Barilius ngawa, Vishwanath & Manojkumar, 2002 from the head water of Thoubal River, at Litan, a tributaries of Chindwin river system at Ukhrul district of Manipur, India. A total of 89 Barilius ngawa were collected fortnightly during the period of one year from January 2015 to December 2015. The length of the fish ranges between 51.0 mm to 113.0 mm which was used for the present study. The estimated parameter ‘b’ (3.289) is significantly larger than the value of 3. Also, the average condition factor and the average relative condition factor are 1.839 and 1.0 respectively. Thus, the results indicate that the fish were thriving very well in the head water of Thoubal River and the environment was good for healthy development of Barilius ngawa.
