| 摘 要： | 选取不同体色的鲤(Cyprinus carpio)、鲫(Carassiusauratus)品种为实验对象,测量和观察了背部鳞片、腹部鳞片,以及彩色斑纹鳞片的色素组成和分布。结果得出,鲤、鲫鳞片上层的色素有黑色素、红色素、黄色素3种,分布于鳞片的后区,其中心区域色素浓密,外缘区域较稀疏,占整个鳞片的百分比为25%～35%。鳞片下层的色素主要是鸟粪素,镶嵌有少量的黑色素、红色素、黄色素,分布于鳞片的后区和前区,约占整个鳞片的百分比为30%～65%。并归纳总结了鲤、鲫中相近体色品种的鳞片色素分布异同点,讨论了鸟粪素在鲤、鲫鳞片上的分布特征,金鲫的体色演化,以及黑背鲤、黑背鲫中黑色素的遗传特点。研究亮点:观察了鲤、鲫背部和腹部鳞片上的色素分布状况,测量分析了鳞片下层色素区、鳞片上层色素区占整个鳞片比例的特点。拍摄了不同体色鲤、鲫鳞片一一对应的色素图谱,找出了相近体色品种的鳞片色素分布异同点,这些研究内容为揭示鲤、鲫多姿多彩的体色提供了理论依据。

| Abstract: | Composition and distribution of chromatophore on back scales, abdomen scales, and color pattern scales were studied on varieties of carp (Cyprinus carpio) and crucian carp (Carassius auratus) with different body colors. The results showed that the chromatophores on upper layer were melanin, red pigment and yellow pigment, which were distributed on the back area and accounted for 25%-35% of the scale; the main chromatophore on lower layer was guanine, with a little melanin, red pigment and yellow pigment, which were distributed on the proparea and back area, and accounted for 30%-65% of the scale. Based on the analysis, we summarized the differences of chromatophore distribution between varieties with similar body color; discussed the distribution of guanine on carp and crucian carp, the evolution of the body color on one of Carassius auratus variety with red color, and the genetic characteristics of melanin on varieties of carp and crucian carp. |
