Age and Growth of Shotted Halibut, <i>Eopsetta grigorjewi</i> (Herzenstein, 1890), in the West Sea of Korea

Abstract

To investigate the age and growth characteristics of shotted halibut, Eopsetta grigorjewi, in the West Sea of Korea, the samples were collected using gill nets throughout 2019. A total of 861 specimens (693 females and 168 males) were analyzed. The BW-TL relations were BW = 0.0034TL3.3278 (R2 = 0.8716) for females and BW = 0.0031TL3.3359 (R2 = 0.8860) for males. This analysis revealed that males exhibited a larger growth rate than females (p 2 =0.7081) for females and TL = 15.037R + 5.0265 (R2 = 0.6992) for males (p t = 83.6 (1 − exp−0.046(t+4.70)) in females (n = 693, p t = 56.8 (1 − exp−0.078(t+2.16)) in males (n = 168, p < 0.05).
