We tested salinity tolerance of grass carp and silver carp eggs and larvae during two phases of development – pre-gas bladder inflation and post gas bladder inflation to the development of the second gas bladder chamber, using 6 different salinity concentrations ranging from 0 to 36 ppt. Growth and developmental rates were also observed after exposure. After the initiation of horizontal swimming, grass carp larvae were tested in a Y-maze to assess any preferences for salinity levels.

This data release includes individual lengths, total dry mass, and taxonomic classification for a subset of adult aquatic insects captured emerging from the surface of wadeable wetlands in cropland and grassland landscapes across a salinity/hydrology gradient (N = 14 wetlands in 2015, N = 15 wetlands in 2016). Sampling was completed in late spring, after ice off was complete and during the local bird breeding season. Wetlands were situated on 3 USFWS Waterfowl Protection Areas and 2 private farms in Stutsman County, North Dakota, USA. Other portions of this data such as sampling locations and pesticide concentrations are reported in Kraus et al. 2021 (https://doi.org/10.5066/P971S7IV)

In the Lamine, Moreau, and Little Chariton rivers, light traps were used to capture larval bigheaded carps moving into tributaries. Traps were set on a weekly basis in each river, at roughly 1-kilometer intervals up to 7 km upstream. Ichthyoplankton tows were done in locations near the confluence of each tributary with the Missouri River, and within the Missouri River itself. Data includes identification of larval fish, size, and developmental information of subsampled invasive carp species. Flow readings were taken at up to five points across the channel with a Marsh-McBirney flow meter, and water quality was measured at the surface with a YSI ProPlus before retrieval of light traps.
