Main Article Content
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.Â We report a value of â€˜bâ€™ 3.1269 and 3.1426 for LWR with respect to total length and standard length respectively, indicating positive allometric growth. The value of â€˜bâ€™ for LLR is less than one, which indicates that growth in total length is less with per unit increase in standard length.Â The value of â€˜Kâ€™ and â€˜Knâ€™ is 0.91 and 0.72 depicts normal well being of fish in its habitat.Â
