During the 1910s three buffalofish species (Catostomidae: Ictiobus cyprinellus, I. bubalus, I. niger) were reared in ponds along the Mississippi River. Individuals of these buffalofishes were transported to locations across the United States to support or establish commercial fisheries, including Roosevelt Lake, Arizona in 1918. During the 1930s-1960s a commercial fishery existed on Roosevelt Lake, ending by 1970. Scarce information exists on Arizona buffalofishes since. From 2018 to 2023 we studied buffalofishes from nearby Apache Lake (adjacent and downstream of Roosevelt Lake) in collaboration with anglers. Here we show that > 90% of buffalofishes captured from Apache Lake are more than 80 years old and that some of the original buffalofishes from the Arizona stocking in 1918 are likely still alive. Using unique markings on old-age buffalofishes, we demonstrate how individuals are identified and inform dozens of recaptures. We now know all species of USA Ictiobus can live more than 100 years, making it the only genus of animal besides marine rockfishes (Sebastes) for which three or more species have been shown to live > 100 years. Our citizen-science collaboration has revealed remarkable longevity for freshwater fishes and has fundamentally redefined our understanding of the genus Ictiobus itself.
在20世纪10年代，三种牛胭脂鱼（胭脂鱼科：Cyprinellus属、I. bubalus、I. niger）在密西西比河沿岸的池塘中养殖。这些牛胭脂鱼个体被运往美国各地，以支持或建立商业渔业，包括1918年运至亚利桑那州的罗斯福湖。在20世纪30年代至60年代，罗斯福湖存在商业渔业，到1970年结束。此后，关于亚利桑那州牛胭脂鱼的信息稀少。2018年至2023年，我们与垂钓者合作，研究了附近阿帕奇湖（罗斯福湖相邻且位于其下游）的牛胭脂鱼。我们在此表明，从阿帕奇湖捕获的牛胭脂鱼中，超过90%的年龄超过80岁，1918年在亚利桑那州放养的一些原始牛胭脂鱼可能仍存活。通过老年牛胭脂鱼身上独特的标记，我们展示了如何识别个体并告知多次重新捕获的情况。我们现在知道，美国Cyprinellus属的所有物种都能活到100岁以上，这使其成为除海洋岩鱼（Sebastes属）之外，唯一有三种或更多物种被证明能活到100岁以上的动物属。我们的公民科学合作揭示了淡水鱼惊人的长寿，并从根本上重新定义了我们对Cyprinellus属本身的理解。
