Abstract:In this paper,we collected data of Pseudosciaena crocea in the breeding farm of Nanji Island Development Co.,Ltd.-Pingyang Zhejiang in Nanji Island from March 19,2005 to May 22,2005.The experimental pond was separated into 4 areas according to the distance from the light source.By 5 kinds of lights(5 colors: green,white,red,yellow,blue;5 kinds of illumination intensities: 100 lx,200 lx,300 lx,400 lx,500 lx) and 7 kinds of nets(black,blue,green,orange,white,bluish green,red) to stimulate Pseudosciaena crocea,their reactions were observed.The results showed that:(1) The reactions to the differences among 7 kinds of nets were highly significant(P<0.01).The percentage of Pseudosciaena crocea swimming through blue and green nets were 64.97%,52.68%,respectively,which was higher than other nets.(2) In the experiment of lights,5 kinds of colors were not significantly different(P>0.05) to the distribution of Pseudosciaena crocea.The 4 areas were significantly different(P<0.01) to the distribution of Pseudosciaena crocea.The differences between Pseudosciaena crocea's trend to higher illumination intensities area(0.5-500 lx) and trend to lower illumination intensities area(0-0.5 lx) was significant(P<0.05).In the higher illumination intensities area,the Pseudosciaena crocea had positive tendency to 300 lx of blue light and 200 lx of green light.
