Abstract
The present study describes the length-weight relationships (LWRs) and length-length relationships (LLRs) for three species: Parambassis baculis (Hamilton 1822), Gagata cenia (Hamilton 1822) and Mystus tengara (Hamilton 1822) from the Jorasar river in Sonitpur district of Assam, India. The study shows positive allometric growth (3.133) for M. tengara, isometric growth (2.916) for G. cenia, and negative allometric growth (2.295) for P. baculis, with regression coefficients (r2) 0.953, 0.969, and 0.955, respectively. The Parameter a was recorded as 0.007 for M. tengara, 0.013 for G. cenia, and 0.030 for P. baculis. The current study will contribute to the conservation of these ichthyofaunas while enhancing fish stock analysis for appropriate management.
