Spotted Bass , like many sport fishes, have experienced range expansion through intentional introductions (i.e., legal stocking and illegal transfers) and migration across the United States. In Illinois, USA, native populations of Spotted Bass occur along the eastern and southern border of the state. We report new records of Spotted Bass in their non-native range of the Illinois Waterway and the Illinois portion of the Upper Mississippi River in addition to collections in their native range in the Illinois sections of the Ohio and Wabash rivers to better understand their current distribution. Continuous, collaborative efforts to track the distribution and expansion of non-native fishes are important for maintaining and establishing native and non-native fisheries management objectives and education, as non-native fishes can influence native species population distribution and dynamics.
像许多游钓鱼类一样，斑 bass 通过有意引入（即合法放流和非法转移）以及在美国境内的迁移，实现了分布范围的扩大。在美国伊利诺伊州，斑 bass 的原生种群分布在该州的东部和南部边界沿线。我们报告了斑 bass 在伊利诺伊水道和上密西西比河伊利诺伊州部分的非原生分布范围内的新记录，此外还报告了在俄亥俄河和瓦巴什河伊利诺伊州段的原生分布范围内的采集情况，以便更好地了解它们目前的分布。持续开展合作努力来追踪非原生鱼类的分布和扩散，对于维持和确立原生及非原生渔业管理目标以及相关教育至关重要，因为非原生鱼类会影响原生物种的种群分布和动态。
