许多鱼类具有紫外线视觉，并显示紫外线模式，这通常在社会交流中发挥作用，特别是在求偶期间。紫外线在水中强烈散射，因此可能用于种内近距离通信而不被捕食者发现。除了红色的腹部和蓝色的虹膜外，雄性三刺鱼的皮肤还具有紫外线反射能力，雌性更喜欢有紫外线的雄性。为了研究紫外线是否也会影响雄性对雌性的视觉偏好，我们采用了二分择偶设计，其中一个雌性可以被一个雄性在两种视觉条件下观察。求爱男性刺鱼喜欢的女性，提出了在全光谱条件下，包括紫外线的条件下，缺乏这种光组件相同的女性。此外，中性密度过滤器的对照试验表明，在紫外线处理的男性偏好不受紫外线+和紫外线-刺激之间的非彩色亮度差异的影响。妊娠女性的反射率测量表明，增强的紫外线之间的对比度的黑暗酒吧模式，这是妊娠女性的特点，和银色的身体部位。
Numerous fishes possess UV vision and show UV patterns, which often play a role in social communication, especially during courtship. UV light is scattered strongly in water and thus might be used for intra-specific close-range communication without being detected by predators. In addition to the red-belly colouration and blue-coloured iris, male three-spined sticklebacks possess UV reflectance on their skin, and females prefer males presented with UV light rather than without. To investigate whether UV also influences male visual preference for females in this species, we used a dichotomous mate choice design in which one female could be viewed by a male in two visual conditions. Courting male sticklebacks preferred females that were presented in full-spectrum conditions including UV to the same females presented in conditions lacking this light component. Furthermore, control trials with neutral-density filters indicated that male preference in the UV treatment was not affected by a difference in achromatic brightness between the UV+ and UV− stimuli. Reflectance measurements of gravid females suggest an enhanced UV contrast between the dark bar pattern, which is characteristic of gravid females, and silvery body parts.
