Abstract: Length Weight Relationship of Paracheaturichthys ocellatus (Day1873) from the creeks of Mumbai was carried out from July 2010 to September 2011. The males ranged in the length of 66-182 mm and weight 1.152-54.801g while females ranged in the length 66-153mm and weight 2.209-38.383g. The juveniles ranged in the length range of 52-65mm and weight of 1.775-3-545g. The parabolic equation was W= -5.1742L3.1041 with high correlation of 0.9961 indicating that fish increased in body weight as it grows in total length in the total population. The coefficient of regression b was 3.1041 for all fishes combined together showing a positive allometric growth. The relative condition factor for males was 1.0126, females was1.0375 and 1.0013 for juveniles. Sex wise analysis of relative condition values revealed that mean Kn values in females (1.0375) was higher than that of males (1.0126). In present study Kn values were higher in males during pre-spawning period while in females it was during post spawning period. In males higher Kn values was observed in the length group of 106-115mm while in females it was 66-75mm. Relative condition factor was never less than 1 through the period of study hence it was in good condition irrespective of feeding or reproductive condition.
