半滑舌鳎Cynoglossus semilaevis Günther和焦氏舌鳎C.joyneri Günther 均隶属于舌鳎科Cyonglossidae的舌鳎属Cynoglossus,系广泛分布在我国近海的底层鱼类。它们具有一定的经济价值。其中半滑舌鳎是该属中个体较大的种类,最大体长可达800毫米以上。素有名贵鱼类之称。惟产量不高。该类鱼多栖息在海湾水域,洄游距离短,活动范围小,是适合增养殖的对象之一。 关于这两种舌鳎的早期形态资料迄今尚未 Cynoglossus semilaevis Günther and C.joyneri Günther, both belonging to the genus Cyonglossidae, belong to the genus Cynoglossus, which are widely distributed in the coastal waters of China. They have some economic value. Among them, the soleus is a larger species of the genus, with a maximum body length of 800 mm or more. Known as a rare fish. However, the yield is not high. The fish habitat in the Gulf waters, migratory distance is short, a small range of activities, is suitable for breeding one of the objects. There is no information on the early morphological characteristics of these two species of tongue
