Observed ages ranged from age 1 +to 4 +using otoliths and vertebra,1 +to 3 +using opercular.

考虑到暗纹东方生物学的特殊性，其鳞片已经退化成小皮刺；鳍骨柔软、中空，皆不适合用来鉴定年龄。

The thymus is located on the edge of the gill cover close to the opercular cavity, triangle, is distributed symmetrically. Lobules of thymus are more evident along with increasing age.

观察到鳜胸腺位于鳃盖与背的联合处，呈三角形，对称分布；胸腺实质随年龄增长分叶逐渐明显，大体可分三个区，外区、中区和内区，中区和内区分别相当于哺乳动物的皮质区和髓质区。

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.

有关暗纹东方养殖生物学和病害的研究已有很多，但对其年龄鉴定却鲜见报道。在整个形目鱼类中仅见绿鳍马面年龄生长的报道，且作为年龄鉴定依据的材料仅限于脊椎骨[1]。

Opening the disease fish opercular,we can see maggot-like worms on gills .A lot of mucus are on the gills at a serious infection and the gill-terminal expands ,there is congestion or bleeding or a "mud drag" phenomenon.

掀起病鱼鳃盖，可见鳃丝上有蛆状虫体，严重感染时，鳃上粘液很多，鳃丝末端膨大，有淤血或出血点，或有"拖泥"现象。

The results showed that the American shad fingerlings stopped opercular movement less than half an hour after anesthetia when the fish were exposed to concentration of MS-222 at 75mg/L, clove oil at 20mg/L and bezocaine at 40mg/L. The fish recovered to normal behaviors again after exposed in air for less than 10min when transferred into fresh water. The shad fingerlings had good anaesthesia for more than 12h at 20-30mg MS-222/L, 8-10mg/L clove oil and 20-30mg/L benzocaine. The anesthetic effects were enhanced at high water temperature and changed with fish sizes. Small fish were more easily in good anaesthesia than the bigger one in MS-222 while the opposite case was found in clove oil and in benzocaine.

麻醉试验结果表明：在较高麻醉浓度（MS-222为75mg/L以上，丁香油为20mg/L以上，苯唑卡因为40mg/L以上）下，鱼很快（30min内）停止鳃盖张合运动，且停止鳃盖运动的鱼在空气中暴露一定时间（10min内）后也能够复苏；在适宜的麻醉浓度（Ms-222为20~30mg/L，丁香油为8~10mg/L；苯唑卡因为20~30mg/L）下，鱼能够进入麻醉状态，且能保持很长时间(12h)；麻醉效果随着水温的升高而增强；在20mg/L MS-222麻醉剂下，小规格鱼较大规格鱼更容易进入麻醉状态，而在10mg/L丁香油和20mg/L苯唑卡因麻醉剂下，小规格鱼却难进入麻醉状态。
