Assessment of length-weight relationship (LWR), length-length relationship (LLR) and condition factor was carried out for Bangana dero in northeastern India, mainly from the Brahmaputra and Irrawaddy (Manipur) River system. We report a value of ‘b’ 3.1269 and 3.1426 for LWR with respect to total length and standard length respectively, indicating positive allometric growth. The value of ‘b’ for LLR is less than one, which indicates that growth in total length is less with per unit increase in standard length. The value of ‘K’ and ‘Kn’ is 0.91 and 0.72 depicts normal well being of fish in its habitat.
