明尼苏达大学德卢斯分校 （University of Minnesota Duluth） 的一项研究发现，赖斯湖国家野生动物保护区 （Rice Lake National Wildlife Refuge） 成功孵化大口水牛鱼的时间间隔为 50 年，目前超过 95% 的种群在 1960 年代之前孵化。 A University of Minnesota Duluth study found a 50-year gap in successful broods of bigmouth buffalo fish in Rice Lake National Wildlife Refuge, with over 95% of the current population hatching before the 1960s. 尽管它们的寿命很长，但幼鱼难以生存，这可能是由于捕食和环境因素。 Despite their longevity, young fish struggle to survive, likely due to predation and environmental factors.
