The length-weight relationship and relative condition factor of Stolephorus commersonii was calculated to assess the significance of allometric factor and the well being. The study was carried out by using the data collected from ring seine and purse seine catches during the year 2010-2011. The length of species in catches ranged from 5 to 14.6 cm with a mean length of 9.24 ± 1.83 cm and the weight ranged from 1 to 25g with an average weight of 6.64 ± 3.96 g. Length-weight relationship calculated for male, female and pooled are W = 0.0070 L3.02, W = 0. 00756 L2.99 and W = 0. 0073 L3.006 respectively. The relative condition factor (Kn) estimated separately for male and female showed monthly fluctuation. The highest Kn values were observed in February and August and the lowest in June for both the sexes.
