Abstract
Age and growth of three-lined tonguefish (Cynoglossus abbreviatus) were studied using samples from the waters off Yosu, Korea, from June to December, 2001. Sagittal otoliths had relatively clear annuli. Each annulus was formed once a year in April. The peak of the gonadosomatic index occurred also in April. The oldest fish observed in this study was 5 years old for females and 4 years old for males. The relationship between the otolith radius (R) and total length (L) was as follows: L=14.921R-2.5318 for females and L=13.527R- 0.5584 for males. The relationship between total length and body weight (W) was as follows: W=0.0008L3.54 for females and W=0.0029L for males. The growth in length of the fish was expressed by the von Bertalanffy's growth equation as: Lt=44.54(1-e-0.16(t+2.69)) for females and Lt=41.52(1-e-0.15(t+3.34)) for males.
