This dataset contains the physical collection information (e.g., sample location, date, gear type) and microsatellite DNA genotype of egg and larval Lake Sturgeon collected in the St. Clair and Detroit rivers in 2015 and 2016. Individuals were genotyped for 18 microsatellite loci (13 disomic and 5 polysomic). Alleles (base pair sizes) were recorded as presence absence scores (1:present, 2:absent, 0:missing data) for all previously observed alleles. Thus individual genotypes were recorded as pseudo diploid dominant phenotypes resulting in individual vectors of length n=205 for each genotyped egg or larval individual.

In this experimental series we studied the swimming capabilities and response of grass carp (Ctenopharyngodon idella) larvae to flow turbulence in a laboratory flume. We compared three different experimental configurations, representing in-stream obstructions commonly found in natural streams (e.g. a gravel bump, a single vertical cylinder, and patches of submerged rigid vegetation). Grass carp larvae (post gas bladder emergence) were introduce to each experimental configuration and subjected to a variety of hydrodynamic forces of different magnitudes and scales. We varied the flow velocities and water depths and found threshold values of turbulent kinetic energy and Reynolds stresses that triggered an apparent...

This dataset documents the number of normally developed hatched free embryos, abnormally developed hatched free embryos, and viable unhatched embryos from two laboratory trials (shovelnose sturgeon during April and pallid sturgeon during May 2016) in substrate conditions designed to simulate potential fates within a dynamic riverine environment. Trials were performed with substrate treatments that consisted of clean glass (control), gravel, medium-coarse sand, and fine sand-silt. Medium-coarse sand and fine sand-silt substrates were each tested three ways: unburied, partially buried, and fully buried (1–2 millimeter depth). Pallid sturgeon and shovelnose sturgeon embryos were exposed to trial conditions from the...

The data set contains sampling data, catch data, and biological data associated with a broad-scale experiment to examine free embryo dispersal and larval settlement of endangered pallid sturgeon (Scaphirhynchus albus) in the Missouri River of eastern Montana and western North Dakota. On 20190701, two age groups of pallid sturgeon including 771,707 1-day post-hatch (dph) free embryos and 200,786 5-dph free embryos were released in the Missouri River where dispersal in the water column was assessed through 150 miles. Following dispersal, beam trawl sampling of benthic habitats was conducted to verify settlement and quantify the spatial extent of settlement. Trawling was conducted for nine consecutive weeks from 20190716...

This dataset contains data collected on various vessel operations on the Great Lakes and their connecting channels, primarily the St. Clair River, Lake St. Clair, Detroit River, and western Lake Erie, although other locations have been sampled and included in this dataset. This dataset contains the field variables, environmental conditions, larval catches (numbers), larval fish identifications, and associated auxiliary information with the sampling locations.

This dataset documents the length and developmental stage of pallid sturgeon and shovelnose sturgeon free embryos from the time of hatch through melanin plug expulsion (the approximate onset of exogenous feeding) reared in the laboratory at a constant temperature. Free embryos from 4 pallid sturgeon crosses and 7 shovelnose sturgeon crosses were reared separately in the laboratory at a mean temperature of 17.8 degrees Celsius (range 17.3–18.4 ). Beginning on the day of hatch, a minimum of three to six free embryos from each cross was randomly sampled and preserved in 10% neutral buffered formalin at 2 to 12-hour intervals, depending on age. Free embryos were microscopically examined and assigned a developmental...
Growth and survival of Colorado squawfish, Ptychocheilus lucius, larvae under fluctuating 18, 22, and 26 degrees C (5 degrees C diel fluctuations) and constant 18, 22, 26 degrees C, and 30 degrees C temperature conditions and ration size corresponding to 12.5, 28, 64,142, 320 brine shrimp nauplii fish(-1) day(-1) was determined from laboratory experiments. Growth was optimal at 31 degrees C and high at temperatures of 26 degrees C to 30 degrees C, at the highest food abundance. Lowest growth was under lowest food rations and highest temperatures. Growth of Colorado squawfish larvae declined substantially at temperatures < 22 degrees C. Neither growth nor survival was significantly different between fluctuating or...

The data set contains sampling and catch data associated with a broad-scale experiment to examine dispersal of endangered pallid sturgeon (Scaphirhynchus albus) free embryos in the Missouri River of eastern Montana and western North Dakota. On 20190701, two age groups of pallid sturgeon including 771,707 1-day post-hatch (dph) free embryos and 200,786 5-dph free embryos were released and recaptured through 20190708 from six sampling sites in a 150-mile reach of the Missouri River. The free embryos were sampled using multiple boats and crews at the sites, and sampling for the free embryos was conducted at the river bed (bottom samples), in the middle of the water column (mid-water samples), and at the river surface...

In 2019, an experimental release of nearly 1.0 million free embryos of federally endangered pallid sturgeon (Scaphirhynchus albus) was conducted in the Missouri River of eastern Montana and western North Dakota. Dispersal of the free embryos and survival of the benthic larvae was assessed from 20190701 to 20190909 through 150 miles of the river. The data sets contain mean daily discharge and hourly water temperature data for the Missouri River, and mean daily discharge data for the Yellowstone River. Dates of the data extend from 20190701 to 20190909. Discharge data for the Missouri River were obtained from USGS gage 06177000 near Wolf Point, Montana. Discharge data for the Yellowstone River were obtained from USGS...
