| 为探究观赏鱼是否对背景颜色存在选择偏好性，以红白鲫（Carassius auratus）为研究对象，分别记录个体和群体条件下红白鲫在不同彩色（红、橙、黄、绿、青、蓝、紫）背景和白色背景中的停留时间以及往返次数。结果显示，在个体条件下，红白鲫在白色和彩色背景中的停留时间没有显著差异（P>0.05），在各单色背景中的停留时间也没有显著差异（P>0.05）；且其在白色与不同彩色背景间的往返次数从大到小依次为：绿色（17.5次）>蓝色（15.7次）>青色（15.3次）>紫色（13.4次）>橙色（12.0次）>红色（10.0次）>黄色（9.0次）。在群体条件下，与白色背景相比红白鲫在橙色、黄色背景中停留时间显著更长 (P<0.05)，而在红色背景中停留时间显著更短(P<0.05)，而在其他彩色背景中停留时间没有显著差异（P>0.05）；不同单色背景对红白鲫的停留时间有显著影响（P<0.05），其中在橙色、黄色背景中停留时间显著长于红色背景（P<0.05），而其他单色两两之间停留时间无显著差异（P>0.05）；且其在白色与不同彩色背景间的往返次数从大到小依次为：红色（15.1次）>橙色（14.0次）>黄色（13.6次）>蓝色（12.2次）>绿色（11.8次）>青色（10.2次）>紫色（9.1次）。研究表明，红白鲫对背景颜色具有一定的选择偏好，特别是在群体条件下偏好于橙色和黄色，不喜欢红色。 |

| Research has shown that color influences fish feeding, avoidance behavior and degree of activity, thus affecting their growth and health. However, there is still disagreement about whether fish actually display a preference for certain colors. In this study, we explored the preference of Carassius auratus (goldfish) for different background colors. Experiments included the behavior of a single fish and groups of three fish in the presence of differently colored backgrounds: white (control), red, orange, yellow, green, cyan, blue and purple. The experiments were conducted in a fish tank (100 cm×45 cm×50 cm) and the background of the tank was divided into two equal parts (50 cm×45 cm×50 cm), a white background on one side and a colored background on the other. The round trip frequency (number of moves between the two sides of the tank) and residence time by the test fish in each side of the tank were recorded for each color background. Differences in the residence time by individual fish were not significant between the white background and any of the seven background colors tested (P>0.05)．Under the same conditions, the roundtrip frequency between the different color backgrounds and the white background followed the order: green (17.5 times), blue (15.7 times), cyan (15.3 times), purple (13.4 times), orange (12.0 times), red (10.0 times) and yellow (9.0 times). For the groups of three fish, the times spent in the treatment side with orange and yellow backgrounds were significantly longer than in the control side, but the residence time in the red background side was significantly shorter than in the control side (P<0.05). The residence times in the treatment side with the other four color backgrounds were not significantly different than the residence time in the control side (P>0.05). The background color significantly affected the residence time by goldfish in groups (P<0.05). Residence times in the treatment side with orange and yellow backgrounds were significantly longer than with the red background (P<0.05), but residence time differences among the other color backgrounds were not significant (P>0.05). The roundtrip frequency for groups of red-white crucian carp followed the order: red (15.1 times), orange (14.0 times), yellow (13.6 times), blue (12.2 times), green (11.8 times), cyan (10.2 times) and purple (9.1 times). In conclusion, goldfish display a preference for yellow and orange backgrounds and tend to avoid a red background. These results add to our knowledge of fish behavior and provide a reference for selecting the background color of aquariums for ornamental goldfish. |
