摘　　要：对东白令海水域双线鲽(Lepidopsetta bilineata)、太平洋拟庸鲽(Hippoglosso-ides elassodon)和阿拉斯加鲽(Pleuronectes quadrituberculata)等三种经济鲽类的捕捞群体结构和生长特性进行比较。得出结论是:(1)捕捞群体结构复杂;(2)渐近体长和渐近体重较大、寿命长、K值小;(3)雌鱼比雄鱼个体大、生长快、寿命长;(4)三种鲽类的捕捞群体结构和生长特性有明显差异。The main conclusions are:(1)Their fish stock structure is complex;(2) Their L∞ andW∞ are relatively big,life-spans are long,and k-values are small;(3) The females havebigger size,higher growth rate and longer life-span than males;(4) There are noticeabledifferences among the three flatfishes in their fish stock structure and growth characteristics.
