Comparative length-weight relationship of two species of catfishes, <i>Arius caelatus </i>(Valenciennes, 1840) and <i>Arius tenuispinis </i>(Day, 1877) from Mumbai waters⁺

Abstract

266-269Based on the length weight data collected from New Ferry Wharf (NFW), Sasoon Docks (S.D) & Versova landing centres, the length-weight relationship for two important catfishes, Arius caelatus and A. tenuispinis from Mumbai waters has been reported in the present communication. There is no significant difference in growth between sexes for both the species, based on the ANACOVA test. Length-weight relationship derived were W = 0.00419 * L 3.263 (R2 = 0.899) and W = 0.0306 * L 2.720 (R2 = 0.953), for A. caelatus and <i style="mso-bidi-font-style: normal">A. tenuispinis respectively. Growth pattern study showed isometric growth for A. caelatus and A. tenuispinis.</i
