【摘要】 <正> 趋向性(tropism)是动物心理学的研究内容之一,而动物的趋光性或称向光性(phototaxis)又是趋向性的主要特征。由于灯光捕鱼实践的需要,世界各国(苏联、日本等)都在积极地开展鱼类趋光行为的研究。本文较系统地介绍这方面的概况并着重引述我们自己在这方面所取得的研究成果。更多还原

【Abstract】 The paper describes the phototactic types of fishes in the photogradient. The phototactic behaviour depends not only on the strength of illumination, but also on the wave length of various lights. Influence of moon light was also investigated. It is found that when the influence of background light weakens, the phototactic behaviour increases with the increasing light intensity. Finally, a theoretical analysis for phototactic behaviour of fishes is suggested.Basic research on the photctactic behaviour of fishes is not only significant for understanding the influence of light on fish behaviour, but also has implications for comparative psychology.更多还原
