关于鱼类趋光特性的研究,国外已有报导。例如,鱼在光梯度条件下选择最适照度区、不同生理生态因素、月光、颜色光对鱼类趋光性的影响等已有不少研究。 蓝圆鲹(Decapterus maruadsi T.＆ S.)、鲐鱼(Pneumatophorus japonicus Houtt)是我国主要的中上层鱼类资源。为此,通过光梯度实验,研究这两种鱼属于哪种趋光类型及其最适照度区的范围,研究背景光(模拟月光)、不同颜色光对它们的趋光性的影响,这些都将对灯光捕捞实践中光强范围、颜色光的选择、克服月光影响的措施等提供重要的科学根据。 About fish phototaxis research, has been reported abroad. For example, fish in the light gradient conditions to select the most appropriate illumination area, different physiological and ecological factors, moonlight, color light on fish phototaxis, etc. There have been many studies. Decapterus maruadsi T. & S. and Pneumatophorus japonicus Houtt are the main pelagic fish resources in China. To this end, the light gradient experiment to study the two types of fish are the type of phototaxis and the most suitable illumination area, the study of the background light (moonlight), different colors of light on their phototaxis, which will light Fishing practice light intensity range, the choice of color light, measures to overcome the impact of moonlight provide important scientific basis.
