We investigated the ecological characteristics and proximate composition of Muraenesox cinereus off the southern
coast of Korea. Anal length distribution, sex ratio, condition factor of M. cinereus individuals caught by costal complex
(longline) fisheries were investigated from June to October 2018. The mean anal length was 23.5 cm, which was
less than L50, indicating that the individuals were mostly immature. Sex ratio is 9:1, we captured 382 females and
29 males, which produced a significantly different ratio (P<0.05). Condition factor remained constant over the study
period. The proximate composition of M. cinereus individuals was analyzed from July to October 2018. No significant
differences in moisture, crude lipid, crude protein, and ash content were observed between individuals caught
in summer and those caught in fall.
