三疣梭子蟹分布广,资源丰富,经济价值高,是我国重要的海洋水产资源之一。它的趋光行为表明其视觉特性在生活中占重要位置。目前,对无脊椎动物视觉研究多以昆虫和头足类为对象。虽然Wald等对马蹄蟹、蜘蛛蟹等的色觉方面有过研究,但未能得出一致结论。郑微云、罗会明于1979年所发表的论文,曾用行为方法对三疣梭子蟹色觉进行过研究,但不够深入。我们试图用电生理方法对三疣梭子蟹的视觉特性作较系统分析,为了解甲壳动物视觉特性提供资料。
Portunus trituberculatus widely distributed, rich in resources, high economic value, is one of China’s important marine aquatic resources. Its phototropic behavior shows that its visual characteristics are important in life. At present, the study of invertebrates mostly focuses on insects and cephalopods. Although Wald et al. Have studied the color vision of horseshoe crabs, spider crabs and the like, they failed to come to a conclusion. Zheng Weiyun, Luo Huiming published papers in 1979, had used behavioral methods of Portunus tritubalus color vision has been studied, but not enough depth. We attempted to electrophysiologically analyze the visual characteristics of Portunus trituberculatus in order to provide information on the visual characteristics of crustaceans.
