摘要:

本试验研究了循环水养殖条件下白条双锯鱼（Amphiprion frenatus）幼鱼在不同光照环境中的生长状况和体色变化特点。设置白色、红色、黄色、蓝色、绿色五个光照试验组，每组三个重复，试验周期120d。结果表明，各试验组幼鱼存活率和特定生长率均无显著性差异（P>0.05），增重率在红光组和绿光组间差异显著（P<0.05）。试验鱼红光组红色皮肤胡萝卜素含量显著高于蓝光、黄光和绿光组（P<0.05）；白光组红皮中胡萝卜素含量显著高于蓝光组（P<0.05）；在眼、肝、肌肉和白色皮肤组织中胡萝卜素含量在各试验组间无显著性差异（P>0.05）。白光组肝组织中酪氨酸酶活性活性显著高于红光组（P<0.05）；在眼、皮肤、肌肉组织中各试验组酪氨酸酶活性无显著性差异（P>0.05）。研究表明，在循环水养殖条件下，白条双锯鱼在红光环境下体表类胡萝卜素含量增加，而酪氨酸酶活性减弱，有提高鱼体色泽鲜艳度的作用，此研究结果可为人工养殖海水观赏鱼的体色改善提供理论依据。

Abstract:

Four triplicated treatment groups of juvenile tomato clownfish Amphiprion frenatus, a common marine ornamental fish, were treated under different light colors, i.e., red, yellow, blue, and green, respectively, against a white light group as the control, to study the impact of environmental light color on the body color and the growth. The experiment lasted for 120 days. The result show the five treatment groups had no significant difference (P>0.05) in specific growth rate. The red and green treatment groups had significant difference (P<0.05) in weight gain rate. The carotene content in red skin of red group was significantly higher than blue, yellow and green (P<0.05) groups', and it was also significantly higher in white group than blue group (P<0.05). In addition, there was no significant difference in eye, liver, muscle and white skin in carotene content (P>0.05). The tyrosinase activity of liver of white group was significantly higher than red group (P<0.05), and no significant difference in eye, skin and muscle (P>0.05). Therefore, red light is useful for increasing carotene and reducing tyrosinase activity for the fish, which offers a potential application of color improvement for marine ornamental fish.
