abstract
The present investigation documents the relationship between Total length (TL)-Weight (W), Standard length (SL)-Weight (W) and Total length (TL)-Standard length (SL) for two bariline fish species from Manu River, Tripura. The study has been done on 80 samples of Barilius bendelisis with size ranged from 4.30 to 15.55 cm and 77 samples of Barilius barna with size ranged from 4.62 to 10.19 cm in total length for a period of 12 months. The Total length (TL)-Weight (W) relationships were found to be W=0.0100TL2.99 and W=0.0081L3.14 for Barilius bendelisis and Barilius barna respectively. The Mean relative condition factors (Kn) were found to be 1.014±0.023 and 1.043±0.025 for Barilius bendelisis and Barilius barna respectively which shows the good health and condition of the fishes.
