【摘要】 本文研究了东海宽体舌鳎的鳞片形态、年轮特征及其生长规律。结果表明:宽体舌鳎直至5龄生长尚未停止,但2龄前生长最快,以后生长速度逐渐降低,并且在各年龄阶段全长、体高、体厚的生长是不同步的,由此导致了各年龄阶段鱼体型的变化,高龄鱼比低龄鱼更肥胖、宽厚。

【Abstract】 Based on the specimens collected from the East China Sea ,observationson the age of cynoglossus robustus were made and its growth specificity wasstudied. The results of statistical analysis show that cynoglossus robustus of1-5 years old is in growth stage. The growth is the fastest at 1-2yearsold,he growth being gradually getting slow after 2 years old,In the diff- erent age classes ,the growth rate of body length, body width and body heightis different so its body shape is also varied.
