Inland fisheries, defined as finfish caught in lakes, rivers, and other water bodies, provide economic value and a source of protein at local and international levels. However, no comprehensive compilation of U.S. inland commercial fisheries exists. We sought to obtain data across all 50 states during 1990–2015 and noted a small, but significant, decline in harvest. The minimum harvest averaged 41,427 tonnes during 2009–2015 and peaked in 1995 with a minimum harvest of 49,951 tonnes. During 2009–2015, harvest and taxonomic composition varied regionally: eastern interior (the highest regional harvest, dominated by coregonines and carp), western interior (carp and Clupeidae), Gulf (catfish and Clupeidae), Pacific (salmonines), and Atlantic (the lowest regional harvest, dominated by catfish and Clupeidae). Our data compilation of commercial landings was more than double the current limited national inland harvest statistics, which might be indicative of an under appreciation for the value of inland fisheries that can have consequences when policy decisions are made regarding competing sectors for water usage.

美国内陆商业渔业趋势

内陆渔业被定义为在湖泊，河流和其他水域中捕捞的有鳍鱼类，在当地和国际层面提供经济价值和蛋白质来源。但是，不存在美国内陆商业渔业的全面汇编。我们试图获取1990年至2015年所有50个州的数据，并注意到收成略有下降，但幅度很大。2009-2015年的最低收成平均为41,427吨，1995年达到最高，最低收成为49,951吨。在2009–2015年期间，区域内的收成和生物分类组成有所不同：东部内陆（区域性收成最高，以金刚子和鲤鱼为主），西部内陆（鲤鱼和C科），海湾（cat鱼和and科），太平洋（鲑鱼）和大西洋（区域收成最低，主要是cat鱼和lu科）。
