| 摘 要： | 对采自日本北海道宗谷近海的玉筋鱼(Ammodytes personatus)和北方玉筋鱼(A.hexaperus)进行了部分形态学和生物学特征的分析比较.2种玉筋鱼在体长体质量关系式、性腺成熟系数等生物学特征上存在显著差异,单因子方差分析表明,2种玉筋鱼的脊椎骨数存在极显著差异(P＜0.01),但有较高的重叠率(70%).采用耳石角度对2种玉筋鱼进行研究,发现玉筋鱼耳石角度的平均值(86.8±0.4)°]显著小于北方玉筋鱼(93.0±0.5)°](P＜0.05).利用耳石角度对2种土筋鱼的判别准确率较高,平均为84.3%,可以作为鉴别2种玉筋鱼的1个形态学参数. |

| Abstract: | Morphological and biological characters of Ammodytes personatus and A.hexaperus from the waters nearby Soya in Japan were measured.The results indicated that there was some variance between the two species based on the function of body length and body weight and gonadosomatic index(GSI).One-way ANOVA results showed that though there was great(70%) overlap in vertebra numbers,difference between the two Ammodytes species in vertebra numbers was extremely significant(P<0.01).The otolith angle was firstly used ... |
