SummaryThe flameback pygmy angelfish Centropyge aurantonotus, highly appreciated and valued by the aquarium market, is heavily harvested and traded. Temperature is one of the abiotic factors that has the most influence on fish development, especially in the early stages of life. For captive production, it is essential to know the appropriate environmental parameters for each species. In this sense, this study aimed to evaluate the influence of temperature on the embryonic development and hatching rates of C. aurantonotus incubated at six different temperatures (20, 22, 24, 26, 28, 30°C). Embryonic development events were very similar in terms of morphological and chronological characteristics compared with other species of the genus Centropyge. Incubation time was inversely proportional to temperature. The treatment at 22°C required twice the time of that required by 30°C treatment for hatching to occur. The best incubation temperature range was 24–28°C. Values below 22°C and at 30°C showed lower hatching rates compared with other treatments. Based on these results, the recommended temperature at which to incubate C. aurantonotus eggs is between 24–28°C.

热对火背侏儒神仙鱼 Centropyge aurantonotus 卵胚胎发育和孵化率的影响

总结火背侏儒神仙鱼橙皮螳螂受到水族市场的高度赞赏和重视，大量收获和交易。温度是对鱼类发育影响最大的非生物因素之一，尤其是在生命的早期阶段。对于圈养生产，了解每个物种的适当环境参数至关重要。从这个意义上说，本研究旨在评估温度对胚胎发育和孵化率的影响。C.橙皮鱼在六种不同的温度（20、22、24、26、28、30°C）下孵育。与该属的其他物种相比，胚胎发育事件在形态和时间特征方面非常相似中心线. 孵育时间与温度成反比。22°C 处理所需的孵化时间是 30°C 处理所需时间的两倍。最佳孵化温度范围为 24–28°C。与其他处理相比，低于 22°C 和 30°C 的值显示出较低的孵化率。根据这些结果，建议的孵育温度C.橙皮鱼鸡蛋的温度在 24–28°C 之间。
