对日本九州岛西南海域的褐牙鲆（Paralichthysolivaceus）305尾（全长265- 875 mm）进行了年龄和生长的研究。从边际生长指数的变化来看，年龄标记形成于产卵期的1 ~ 4月。虽然由于样本不足，在雄性中未获得显著数据，但雌性的生长用Lt=840.45[1-exp {-0.406（t+0.067）}]（Lt，全长; t，年龄）表示。比较了日本19个地区比目鱼的生长情况，将其分为3组：东北区、北陆区和濑户内海生长缓慢，山阴区生长中等，关东区以南太平洋沿岸和九州区生长迅速。
Age and growth of Japanese flounder Paralichthys olivaceus were studied with 198 females and 107 males, totaling 305 specimens (265-875mm in total length) collected in the sea of south-west Kyushu. Judging from changes of the marginal growth index, age marks were formed during the period from January to April in the spawning season. Though significant data was not obtained in males due to shortage of specimens, the growth of females was expressed with the Bertalanffy curve of Lt=840.45[1-exp {-0.406(t+0.067)}] (Lt, total length; t, age). The growths of Japanese flounders around Japan were compared among 19 localities, and divided into three groups: the slow growth in the Touhoku and Hokuriku Districts and the Seto Inland Sea, the intermediate growth in the Sanin District, and the fast growth in the Pacific coast south of the Kantou District and around the Kyushu District.
