Length-Weight Relationship and Sex Ratio of some Cyprinid Fish Species from Taungthaman Lake Dr.Soe Soe Aye The present study describe the length-weight relationships LWR condition factor (K), relative condition factor (Kn) and sex ratio of three cyprinid small indigenous fish species; Amblypharyngodon atkinsonii, Puntius sarana and Puntius chola from Taungthaman Lake, Mandalay Region. A total numbers of 252 A. atkinsonii, 220 P.sarana and 249 P.chola were collected from November 2015 to February 2016. In LWR (W= aLb) values of exponent 'b' were observed to be 2.577, 2.519, 2.539 for male, female and combined of A. atkinsonii, 2.913, 2.751, 2.809 for male, female and combined of P.sarana and 2.684, 2.784, 2.746 for male, female and combined of P.chola. The correlation coefficient 'r' was observed to be 0.91, 0.905, 0.862 for male, female and combined of A.atkinsonii, 0.869, 0.9, 0.875 for male, female and combined of P.sarana and 0.85, 0.918, 0.914 for male, female and combined of P.chola. The values of k were 1.06 in A.atkinsonii, 1.48 in P.sarana and 1.37 in P.chola from pooled data. The values of Kn were observed to be 1.05, 1.06 for male and female of A.atkinsonii, 1.09, 1.05 for male and female of P.sarana and 1.07, 1.05 for male and female of P. chola. The sex ratio (M: F) were 1:5 in A. atkinsonii, 1:6.3 in P.sarana and 1:6 in P.chola from pooled data. Moreover, it is fluctuated between 1:4-1:9 in A. atkinsonii, 1:4-1:9.5 in P.sarana and in 1:3.8-1:5.3 in P.chola for different month. It can be concluded that the length-weight relationship of three small indigenous species in both sexes combined, indicates almost negative allometric pattern of growth in the study period. Throughout the study period females were predominant over males. 2017 http://hdl.handle.net/20.500.12678/0000000261 https://meral.edu.mm/records/261
