unknown. Length-weight relationship and relative condition factor (Kn) of freshwater mudeel, Monopterus cuchia (Hamilton) from Mymensingh, Bangladesh were studiedfrom 261 specimens ranging from 19.0-89.5 cm in total length, for six monthsfrom March-August 2000. The equations for the length-weight relationshipswereLog W= -3.13+3.13 x Log L (for males)Log W= -3.41+3.30 x Log L (for females)Log W= -3.12+3.13 x Log L (for sexes combined).The relationships were significant at 0.1% level in all cases and cube law wasfollowed at 95% confidence limit indicating isometric growth pattern. Relativecondition factor (Kn) values ranged from 0.76-1.16 (SD ± 0.13 mean Kn 1.03) formales, 0.82-1.23 (SD ± 0.15 mean Kn 1.06) for females and 0.88-1.18 (SD ± 0.11mean Kn 1.04) for sexes combined. Maximum relative values were observed insmaller sized fishes. Relative condition factor was found to be high during themonsoon months (spawning period) from April -June reflecting the maturity ofthe fish. First maturity was found to attain at 25.2 cm in total length. Thelength-weight relationship and condition factor showed that the growth of M.cuchia from Mymensingh, Bangladesh is quite satisfactory.
