  • ABSTRACT

    The small yellow croaker Larimichthys polyactis is an important ecological and commercial species in the waters of Korea. Based on samples purchased monthly from a market from 2019 to 2021, except during the closed season, we analyzed the age and growth of the small yellow croaker using 894 otoliths. The total lengths of the small yellow croaker ranged from 12.0 to 38.9 cm, which is a sufficient length range for analyzing age structure and growth parameters. The translucent zone, formed during the spawning season in June, was counted as the annual mark. The estimated ages were 0-10 years, and the 38.9 cm individuals were 7 years old, while the 34.2 cm individuals were 10 years old. The highest proportion in this study (86.8%) was 0-3 years. The von Bertalanffy growth model was obtained as Lt=41.2(1-exp-0.20(t+1.50)).
