Age and Growth Characteristics of Okamejei kenojei in the West Sea of South Korea According to Coronal Vertebral Microstructure

In this study, the growth and age characteristics of Okamejei kenojei in West Sea South Korea were examined, specimens collected by bottom trawls from January to December 2019. The relationship between disc width (L) body weight (W) was W = 6.1 × 10−3 L3.40. Age determined measuring annuli on vertebral centrum surface, which forms around June every year. spawning period extrapolated monthly changes gonadosomatic index June–July. radius width, analyzed separately for females males, as L 16.159R0.6145 15.543R0.6851, respectively. Finally, O. growth, that is, at a certain (t), expressed using von Bertalanffy equation Lt 58.70(1 − e−0.21(t+0.12)) 53.94(1 e−0.26(t+0.05)) males. This study provides basic data future research more efficient fish stock management.
