Artificial light at night (ALAN) is increasingly recognised as a major threat to conservation, causing physiological and behavioural impacts on species adapted to a predictable day-night cycle, including the disruption of reproductive processes. This study investigates the influence of spectral composition of ALAN on Amphiprion ocellaris reproductive success. We compared spawning frequency, clutch size, embryo quality and hatching success of A. ocellaris exposed to ALAN with warm-white and cool-white spectra to fish held in control (12 h day: 12 h night) conditions. The presence of ALAN, regardless of light colour treatment, increased the interval (number of days) between spawning events, and eggs developing under ALAN were smaller than eggs developing under control conditions. Hatching success was influenced by both the presence of ALAN and spectral composition of the light, with fewer embryos hatching under cool-white light compared to warm-white light treatments. As light pollution continues to spread, more research is needed to understand the extent of the impacts of ALAN on marine organisms and to identify effective management strategies.

越来越多的人认为，夜间人工光（ALAN）是保护的主要威胁，会对适应可预测的昼夜循环的物种造成生理和行为影响，包括生殖过程的中断。这项研究调查了ALAN的光谱成分对两栖双翅目生殖成功的影响。我们比较了A. ocellaris的产卵频率，离合器大小，胚胎质量和孵化成功率将其暴露于具有暖白色和冷白色光谱的ALAN中，以使鱼类处于对照（白天12小时：夜晚12小时）的条件下。无论是否进行浅色处理，ALAN的存在都会增加产卵事件之间的间隔（天数），并且在ALAN下发育的卵比在对照条件下发育的卵小。孵化的成功受到ALAN的存在和光的光谱组成的影响，与暖白光处理相比，在冷白光下孵化的胚胎更少。随着光污染的继续扩散，需要更多的研究来了解ALAN对海洋生物的影响程度并确定有效的管理策略。
