Abstract:
Some freshwater teleost fish have pigment cells whose arrangement and shape are affected by the environment. Natural light has a wide range of light intensity. Fish are sensitive to the background and exposed light colour. Fish body colour is a significant criterion in fixing its market value, whether it is ornamental or edible. By favourable light exposure, a culturist may get a good market value of fish on most ethical grounds. In this study, we recorded the changes in melanophore response with the changes in light colour on Channa punctata. Adult fish were treated with monochromatic lights (darkness, white, blue and red light) for 5 and 28 days. After treatment, their body colour and melanophore size, number, length and the number of dendrites were studied. The results showed a significant influence of monochromatic light on melanophore arrangement in fish skin. The data showed that blue light is appropriate for the overall species colour of photic C. punctata. Continuous black or white light caused severe damage to the fish\'s appearance.
摘要:
一些淡水硬骨鱼具有色素细胞,其排列和形状受环境的影响。自然光具有宽范围的光强度。鱼对单光颜色敏感。鱼体颜色对固定其市场价值具有重要意义,无论是观赏还是食用。通过良好的光照,文化主义者可能会在大多数道德基础上获得良好的鱼类市场价值。在这项研究中,我们记录了Channapunctata上黑色素反应随浅色变化的变化。成年鱼用单色光处理,完全黑暗,白色,蓝色,红灯持续5天和28天。治疗后,它们的体色和黑色素大小,number,研究了树突的长度和数量。结果表明,单色光对鱼皮中黑色素细胞的排列有显着影响。数据显示,蓝光适合于光点滴梭菌的整体物种颜色。连续的黑色或白色光对鱼的外观造成严重损害。
