Description A total of 546 samples (365 males and 181 females) of Coilia dussumieri were collected randomly from the trawl landings at Digha (West Bengal) Fishing Harbour during January 2014 to December 2016. Length ranged from 9.0 to 16.5 cm and weight from 4 to 16 g for males and in females, the length ranged from 12.0 to 17.0 cm and weight from 4 to 14 gm. The regression equation for length-weight relation in males and females was Log W = -1.30346 + 1.943241 logL (r =0.22596) (males) and Log W = -2.0008 + 2.53047 logL (r =0.44652) (females). The slope in the relation showed negative allometry in both the sexes. Highest condition factor of 0.34±0.20 in males was observed in December and January and the lowest of 0.28±0.16 was reported in March, July and October. For females, the highest condition factor was observed in January and September of 0.33±.019 and the lowest of 0.27±0.16 was in June and July.
