Reproductive biology of Channa punctata (Bloch, 1793) from Mandalay Environs Htay Htay Aung Mie Mie Sein A total of 383 specimens of Channa punctata were collected from Mandalay environs during the study period from June, 2016 to May, 2017. Sex ratio, length-weight relationship, gonadosomatic index, hepatosomatic index, and fecundity were conducted. The total length of females was ranging from 14.5 cm-21 cm and that of weight, ranging from 32 g-120 g. The total length of males, were ranging from 15.5-22 cm and that of weight, ranging from 38.5 g- 140 g. The sex ratio for male to female was 1: 0.76. Gonadal maturity stages namely, immature, maturing, mature and ripe of maturity in both sexes were recognized during the study period. An inverse relation was observed between GSI and HSI values during the study month. The absolute fecundity of C. punctata ranged from 4667.0 - 9143.46 eggs with the relative fecundity varied from 66.27 - 99.76. Fecundity-ovary weight gave a better relationship in comparison to fecundity-total length and fecundity-body weight relationship. However, as the monthly GSI values in male and female of this species were high during June to August and even to September, the spawning season of C. punctata to fall between June to September. 2019 http://hdl.handle.net/20.500.12678/0000000363 https://meral.edu.mm/records/363
