摘要
鱼类体色发育在生物进化、生理生态等方面具有重要的意义,豹纹鳃棘鲈是一种体色变异丰富的珊瑚礁鱼类,在不同环境中呈现出显著差异的体色。本文选取了豹纹鳃棘鲈体色差异个体,并对不同部位的皮肤颜色、色素分布和相关色素酶含量进行了检测和分析。结果显示,鱼体表皮分布着大量黑色素细胞和红色素细胞。黑色个体的黑色素细胞密度较大、黑色素含量较高,黑色素酶含量较低;而红色个体的红色素细胞密度更大、胡萝卜素与类胡萝卜素含量更高,黑色素酶的含量也更高。实验结果表明,豹纹鳃棘鲈的体色差异与黑色素颗粒的聚集、分散程度以及黑色素代谢酶的含量相关,体色鲜艳程度与红色素细胞数量以及胡萝卜素和类胡萝卜素含量相关。本文解释了红黑豹纹鳃棘鲈体色在色素和酶含量方面的差异,为进一步研究其体色变异机制提供了理论依据。
The development of fish body color is an important issue in biological evolution,physiology and ecology.Plectropomus leopardus,a coral reef fish,shows significantly different body colors in different environments.In this paper,P.leopardus individuals with different colors were selected.The skin color,pigment distribution and melanin enzyme levels from different fish body parts were detected and analyzed.The results showed that many melanocytes and red pigment cells were distributed in the fish skin.The black individuals had a higher density of melanocytes,higher melanin content and lower melanin enzyme levels than the reds,while the reds had a higher density of red pigment cells,higher carotene and carotenoids,and higher melanin enzyme levels.The body color depth of P.leopardus was found to be related to the aggregation and dispersion of melanin particles and the levels of melanin-metabolizing enzymes.The brightness of body color was related to the content of red pigment cells and the contents of carotene and carotenoids.These experiments revealed the differences in pigment and enzyme levels between the red and black P.leopardus,and provided a theoretical basis for further study of mechanisms of body color variation.
