Otolith microchemistry for determining natal origins of prey fishes in the Upper Mississippi River System This dataset includes otolith and water chemistry used for determining natal origins of individuals from six species. The dataset contains Sr:Ca and Ba:Ca of water samples for the Mississippi River and tributaries as well as otolith Sr, Ba, Mg values from fishes collected in navigation pools 4, 8, 13, and 26 of the Upper Mississippi River, as well as the Open River Reach of the Middle Mississippi River and the La Grange Pool of the Illinois River. Fishes included Bullhead Minnow, Emerald Shiner, Gizzard Shad, Bluegill, Orangespotted Sunfish, and Yellow Perch. Laser ablation inductively coupled mass spectrometry to quantify natal origins of these prey fish. Upwards of 50-75% of individuals at a given river reach...

Bigheaded carp (Bighead Carp and Silver Carp) are invasive species in the US and have spread throughout most of the lower Mississippi River Basin. Population abundance upstream of Lock and Dam 19 (LD19) on the Upper Mississippi River (UMR) has likely been limited by the high-head dam at this location, which restricts all upstream fish passage to the lock chamber. To determine early-life environments of adult bigheaded carp captured upstream LD19 at the...
