本文对鲈鱼Lateolabrax iaponicus消化系统的形态构造进行了较细致的观察,并对各消化器官与其机能之间的适应关系进行了粗浅的探讨。鲈鱼各消化器官从功能上可分为三部分,即与取食有关的器官、与消化吸收有关的器官和与排便有关的器官。各器官均与其食性和捕食方法相适应。 In this paper, the morphological structure of the digestive system of the Lateolabrax iaponicus was examined in more detail, and the adaptive relationship between each digestive organ and its function was discussed. Each digestive organ of the perch is functionally divided into three parts, namely organs related to feeding, organs related to digestion and absorption, and organs associated with defecation. All organs are adapted to their feeding habits and predation methods.
