We examined the comparative spawning ecology of daggertooth pike conger Mureanesox cinereus and common pike
conger M. bagio in the South Sea of Korea from May 2018 to December 2019. In the South Sea of Korea, the mean
total length (TL) of M. cinereus was significantly smaller than that of M. bagio. The sex ratios of both species were
skewed toward females. The spawning period of M. cinereus was from June to October, while the spawning period of
M. bagio was from August to October. The lengths at 50%, 75%, and 97.5% sexual maturity of M. cinereus females
were estimated as 54.6 cm, 60.4 cm, and 74.1 cm TL, respectively. It was not possible to estimate lengths at sexual
maturity for M. bagio in the South Sea of Korea due to the absence of immature stages.
