Summary

Bighead Carp, Silver Carp and Grass Carp (collectively Asian carp) were introduced to North America in the 1960s and 70s and have established in the lower Mississippi River basin. 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 observed often included [...]

Purpose

Data were collected to identify potential locations of Asian carp spawning and to identify potential conditions that would co-occur with Asian carp spawning. Data could be combined with other samples to get a larger dataset to analyze these trends and to analyze time-series changes in Asian carp spawning in the upper Mississippi River.
