Sand tiger sharks are an iconic large shark species held in aquaria worldwide. They rarely reproduce under managed care, with only seven aquaria reporting limited and sporadic success. For the first time in the Americas, a full-term young was born in an aquarium. The young was the result of breeding among a group of sharks purposefully brought together in 2016 for reproduction. Sharks were maintained in natural seawater and exposed to natural light and seasonal temperature fluctuations similar to their in situ counterparts. Decreased food consumption associated with breeding season and gestation was observed. Gestation time estimated from breeding observations and parturition was 321 days. Although the neonate was stillborn, this was a significant achievement. The husbandry details described within will be useful for other aquaria striving to support the reproduction of sand tiger sharks.

自然环境条件和协作努力为沙虎鲨 Carcharias taurus 在水族馆繁殖提供了成功秘诀

沙虎鲨是世界范围内水族馆的标志性大型鲨鱼物种。它们很少在管理式护理下繁殖，只有七个水族箱报告有限且零星的成功。在美洲，一个足月的幼崽第一次在水族馆出生。幼鲨是一群鲨鱼在 2016 年有目的地聚集在一起繁殖的结果。鲨鱼被饲养在天然海水中，并暴露于与原地鲨鱼相似的自然光和季节性温度波动中。观察到与繁殖季节和妊娠相关的食物消耗减少。根据繁殖观察和分娩估计的妊娠时间为 321 天。尽管新生儿是死产，但这是一项重大成就。
