| 摘 要： | 用耳石、脊椎骨、鳃盖骨等识别和鉴定暗纹东方鲀(Takifugu obscurusAbe)的年龄,在描述其轮纹特征基础上,比较其在判读暗纹东方鲀年龄和生长特征上的异同与准确性。结果表明,耳石磨片上的轮纹特征明显、清晰且规律性强,是最好的年龄鉴定材料;脊椎骨轮纹也很清晰,但测量时有一定难度,也是较好的年龄鉴定材料;鳃盖骨上年轮较难判定,只能作为辅助材料。本文还对牙齿能否作为年龄鉴定材料进行了观测。

| Abstract: | The characteristics of three kinds of determination materials of Takifugu obscurusAbe,otoliths,vertebra and opercular had been described and compared the similarities and difference and veracity As a result,the otoliths are the best structure of judging age because the annual ring is very evidence and regularity;the vertebra is the better,it is difficulty of measure;the opercular is only the assistant material.Among the 72 specimens selected to identify the age of fish using three structures,opercular and otoliths provided respectively the lowest(n=72,62.50%)and highest(n=72,98.61%)number of interpretable preparations.Observed ages ranged from age 1 to 4 using otoliths and vertebra,1 to 3 using opercular.The teeth of Takifugu obscurus Abe also were used for judging the age and we have found out some preparatory result. |
