초록

The maturation and spawning of female Cynoglossus robustus in the South Sea of Korea were examined to understand their maturation and spawning patterns. Based on gonadosomatic index measurements and ovarian histological analysis, spawning was observed between June and August, with peak reproductive activity occurring in July and August. A positive correlation was identified between fecundity and body length, indicating that larger individuals contribute more substantially to reproduction. The estimated lengths at which 50%, 75%, and 97.5% of the population reached sexual maturity were 24.3 cm, 26.1 cm, and 30.6 cm, respectively. Notably, this study focused on female specimens collected from a specific region, which may limit the generalizability of the results. These findings provide updated biological data that are essential for effective fishery resource management and conservation planning.
