This study was aimed to find out the effect of five light spectra (white, LDW; blue, LDB; green, LDG; red, LDR and yellow, LDY) on the visual development and growth performance of turbot (Scophthalmus maximus) larvae. The number (per 100 μm) of cone cells, outer nuclear cells, ganglion cells, the ratio of outer nuclear to cone and ganglion cells, lens diameter and the minimum separable angle were determined. Variations in growth performance in total length, body mass and body colour were also examined. The results showed that the LDB group underwent metamorphosis faster than did the other groups and attained the greatest total length, body mass and light sensitivity. The LDB group also completed the body colour variation prior to the other groups. The LDG group exhibited a high mortality rate since 25 dph (days post‐hatching). We arrived at the conclusions that the spectra could affect the vision and body development of turbot larvae specifically and the blue light had the enhancing efficiency during this process, followed by the white and yellow light. The red light imposed an inhibiting effect on these variations. Our study highlighted the significance of light condition and provided the reference for the farming.

不同光谱下大菱turbo天牛幼虫的视觉可塑性和身体发育

本研究旨在找出五灯会元光谱的影响（白色，LDW;蓝色，六味地黄丸;绿色，LDG;红色，LDR和黄色，LDY）的可视化开发和大菱鲆的生长性能（大菱鲆）的幼虫。确定视锥细胞，外核细胞，神经节细胞的数量（每100μm），外核与视锥细胞和神经节细胞的比例，晶状体直径和最小可分离角度。还检查了生长性能的总长度，体重和体色的变化。结果表明，LDB组的变态速度比其他组快，并且最大长度，体重和光敏性最高。LDB组还先于其他组完成了车身颜色变化。自25 dph（孵化后的几天）以来，LDG组的死亡率很高。我们得出的结论是，光谱可以特别影响turbo类幼虫的视力和身体发育，并且蓝光在此过程中具有增强的效率，接着是白色和黄色的光。红光对这些变化施加了抑制作用。我们的研究突出了光照条件的重要性，并为耕作提供了参考。
