Influence of a high head dam as a dispersal barrier to fish community structure of the Upper Mississippi River: Data In 2013 and 2014, standardized electrofishing was conducted above and below Lock and Dam 19 (i.e., in Pools 19 and 20 respectively) of the Upper Mississippi River (UMR). Sampling was consistent with the UMR Restoration program’s Long Term Resource Monitoring element (LTRM) and The Illinois Natural History Survey’s Long Term Electrofishing program (LTEF) allowing for standardized comparisons among the reaches we sampled and those sampled by the LTRM (Pools 4, 8, 13, and 26) and LTEF (Pools 16-21, and Pool 25). Data in this file is includes A) new data from Pools 19 and 20 and B) data compiled from public sources for other pools (LTRM and LTEF). Generally, data codes are intended to match formatting conventions from... Categories: Data; Tags: Illinois, Impoundments, Missouri, Navigation Pool 19, USGS Science Data Catalog (SDC), All tags...

Data include the number of bigheaded carp eggs and larvae identified using traditional manual sorting techniques, and genetic data derived from quantitative PCR (qPCR) and 4 bigheaded carp markers (SCTM4/5 and BHTM1/2) that were used to identify the amount of DNA in ichthyoplankton tow samples. These data provide information for natural resource agencies and managers who could use this qPCR screening...

Previously published evidence for spawning of these species has been limited in the upper Mississippi River to just below Dam 22 (near Saverton, MO). In 2013 and 2014, we sampled ichthyoplankton at 18 locations in the main stem of the upper Mississippi River from Dam 9 through Dam 19 and in four tributary rivers that empty into the Mississippi River (Des Moines, Skunk, Iowa and Wisconsin Rivers). We identified eggs and larvae using morphological techniques and then used genetic tools to confirm species identity. The spawning events we...

We consolidated these data into intervals of fish within-pool residency and intervals of fish transitions into adjacent navigation pools (i.e., dam passages). The combined data set was then parsed into an "upstream passage" data set (in which downstream passage intervals were censored) and and a "downstream passage" data set (in which upstream passage intervals were censored). We then examined the effects of river...
