| 摘 要： | 目前半滑舌鳎苗种培育技术方面已经取得重大突破，然而，由于半滑舌鳎在人工养殖条件下投喂困难，产业化养殖规模仍受到限制。为了解决半滑舌鳎的投喂摄食难题，本文对其捕食特征、摄食机理等进行了深入研究，并综合分析了半滑舌鳎摄食机理的最新研究成果。认为半滑舌鳎摄食机制具有两种模式：（1）对运动状态饵料，利用机械感觉定位（侧线），利用化学感觉识别（口咽腔味蕾）；（2）对静止状态饵料，利用化学感觉定位（嗅觉），利用机械感觉识别（无眼侧乳头状突）。基于半滑舌鳎的摄食机理，作者认为，对半滑舌鳎营养策略问题，应从在饵料中添加诱食剂增强嗅觉刺激和强化侧线刺激两方面来进行研究。

| Abstract: | Cynoglossus semilaevis Gunter, a deep water flat fish species, is a popular ma- rine species in aquaculture with high market value and a good taste. Although techniques of large-scale artificial breeding have made significant break-through in recent years, which resul- ted in a successful seedling breeding of C. semilaevis, C. semilaevis culture was not successful due to a difficulty in feeding with pelleted diets under industrial conditions. To solve the prob- lems, study of the sensory mechanisms of the tongue sole in feeding is of special significance. The feeding mechanisms of C. semilaevis were reported in this paper according to the late re- search. The author suppose that C. semilaevis has two possible feeding modes. For motile prey, fish use mainly lateral line and gustation in the oropharyngeal cavity for the detection and recognition of prey, and for still prey, olfactory organ and papillae on the abocular side of the head for the detection and recognition of prey. Based on these studies, the author confer that both stimulating the chemistry sense organ and stimulating the mechanism sense organ should be considered to improve the feeding. |
