中国鳜亚科(Sinipercunae)——七种鱼类骨骼形态特征的比较研究

COMPARATIVE STUDIES ON THE SKELETAL CHARACTERISTICS OF SEVEN SINIPERCINAE FISHES OF CHINA

对中国鳜亚科七种鱼类的骨骼进行比较。指出这七种鱼类之间存在着明显的类群差异,提出将鳜亚科分为三个属,即少鳞鳜属Coreoperca)、鳜属(Siniperca)和长身鳜属(Core-osiniperca);广西与福建的斑鳜和大眼鳜不存在种的分化,而福建产暗鳜(S.obscura Nichols)与广西暗鳜在某些骨骼形态特征上存在某些差异。

This paper presents a comparative study on the skeletal characteristics of seven species in Sinipercinae. It is indicated that there are obvious skeletal differences in the seven species. Therefore it is considered reasonable that Sinipercinae be divided into three genera, i. e. , Coreoperca, Siniperca and Coreosiniperca. Comparison of skeletal characteristics is made between S. kneri in Fujian and that in Guangxi and between S. scherzeri in Fujian and that in Guangxi separately. No clear differences have been found and it is considered that there are no interspecific differentiation in S. kneri and S. scherzeri respectively. Comparison of skeletal characteristics between S. obscura in Fujian and that in Guangxi shows that only minor differences exist between them. To determine whether there is specific differentiation,further study is needed.
