Two co-existing species of ribbonfish Lepturacanthus savala (Cuvier, 1829) and Eupleurogrammus muticus (Gray, 1831) were landed by traditional dol net and trawl net in Mumbai waters with the former contributed more in the landings. Fluctuations in the condition factor have been found in both the sexes of L. savala and E. muticus. k value of the former species was highly affected by gonadal maturation than feeding activity where as k value of latter species was highly linked up with feeding intensity than sexual maturity. Female specimens had higher condition factors than males in both the species.
