Effects of metals from historical mining on crayfish in Madison County Missouri USA, 2015 Effects of metals from historical mining on crayfish in Madison County Missouri USA, 2015
Deposits of lead (Pb) and other metals in southeastern Missouri, USA have been exploited since the 1700s. Metal contamination of fish and other aquatic biota, alteration of fish and invertebrate communities, and public health advisories against human consumption of Pb-contaminated fish have resulted. The Little Saint Francis River (LFSR) and its tributaries, which drain the mining...
Complete female and male mitogenomes of the mucket mussel (Ortmanniana ligamentina) Complete female and male mitogenomes of the mucket mussel (Ortmanniana ligamentina)
Data include fasta files of full mitochondrial sequence data for the male and female mitotypes of the mucket (Ortamannia ligamentina). These have been deposited in the NCBI database under BioSample Accession number SAMN39271813, SRA Accession number SRR27608898, and GenBank Accession numbers : PP103562 and PP103563.
Mississippi River fishes collected by a suite of entanglement and entrapment gears; 2020-2023 Mississippi River fishes collected by a suite of entanglement and entrapment gears; 2020-2023
Black Carp (Mylopharyngodon piceus) were imported to the United States for use as a biological control in aquaculture and have since escaped with reproducing populations in the wild. Habitat use and capture of this species has not been well documented in the wild, thus questions about catchability by gears and habitats are present. This dataset represents sampling effort to capture Black...
Evaluation of fish behaviors in response to driven and undriven entanglement nets with emphasis on invasive Silver Carp, Central Missouri, 2015-2016 Evaluation of fish behaviors in response to driven and undriven entanglement nets with emphasis on invasive Silver Carp, Central Missouri, 2015-2016
We used Adaptive Resolution Imaging Sonar (ARIS), which is based on Dual-Frequency Identification Sonar (DIDSON) technology to observe net encounter behaviors of bigheaded carps. Gill nets with four different mesh types (8.9 cm bar mesh) and trammel nets with five different mesh sizes (range 5.1-8.9 cm bar mesh) were evaluated. Net sets were undisturbed, or fish were driven with the...
Black Carp in North America: a description of range, habitats, date, and methods of reported captures May 2018-October 2022 Black Carp in North America: a description of range, habitats, date, and methods of reported captures May 2018-October 2022
Black Carp collections (n=534) by commercial fishers, biologists, and recreational anglers from the Mississippi River basin recorded from 2018 to 2022 are reported here. Geographic coordinates, total length (TL), weight, girth, date of capture, sex, and gear were recorded. Total length was measured from the tip of the snout to the longest caudal fin ray with the caudal fin lobes pinched...
Water chemistry data observed in experimental laboratory mesocosms exposed to different nitrapyrin and nitrogen amendments in the presence or absence of a nitrifier enriched microbial (NEM) community Water chemistry data observed in experimental laboratory mesocosms exposed to different nitrapyrin and nitrogen amendments in the presence or absence of a nitrifier enriched microbial (NEM) community
These data describe the results of a controlled laboratory mesocosm experiment evaluating the effect of nitrapyrin, a nitrification inhibitor, on nitrification in a nitrifier enriched microbial (NEM) community. Parameters described include the water chemistry and nitrapyrin measurement results of experimental mesocosms. Microbial community data is described in a separate data release.
Growth and survival of a Unionid Mussel (Fatmucket, Lampsilis siliquoidea) and a Common Test Benthic Organism (Amphipod, Hyalella azteca) during Chronic Exposures to Mixtures in Sediment Contaminated by Unregulated Industrial Discharges. Growth and survival of a Unionid Mussel (Fatmucket, Lampsilis siliquoidea) and a Common Test Benthic Organism (Amphipod, Hyalella azteca) during Chronic Exposures to Mixtures in Sediment Contaminated by Unregulated Industrial Discharges.
This data set contains toxicity data from 28- and 84-day sediment bioassays to assess the effects of contaminated Kanawha River, West Virginia sediment on juvenile mussels (fatmucket, Lampsilis siliquoidea) and one commonly tested benthic invertebrate (amphipod, Hyalella azteca) following ASTM standard methods for conducting 4-week sediment toxicity tests with the mussel and amphipod. In...
Dike Fields and Macrohabitats of the Lower Missouri River Dike Fields and Macrohabitats of the Lower Missouri River
This project summarizes broad, two-dimensional spatial availability of fish habitat across the Lower Missouri River (from its confluence with the Big Sioux River near Sioux City, Iowa downstream to its confluence with the Mississippi River near St. Louis, Missouri). One of the main objectives of the project was to delineate and categorize dike fields, which we define as areas directly...
Salinity tolerance of grass carp and silver carp during egg and early larval stages Salinity tolerance of grass carp and silver carp during egg and early larval stages
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...
Light trap and larval trawl collection of bigheaded carp in the Missouri River Basin, 2016 Light trap and larval trawl collection of bigheaded carp in the Missouri River Basin, 2016
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...
Invasive carp harvest data and surveys of commercial fishers in support of stock assessment and abundance models, Kentucky Lake and Lake Barkley, 2009-2021 Invasive carp harvest data and surveys of commercial fishers in support of stock assessment and abundance models, Kentucky Lake and Lake Barkley, 2009-2021
The Kentucky Department of Fish and Wildlife Resources and Tennessee Wildlife Resource Agency conducted observations onboard commercial fishing vessels. During these observations total lengths were collected from a subset of that capture which we have used to develop a length-based stock assessment of invasive carp. The first dataset represent harvest from the invasive carp harvest...
Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023 Results of elemental analyses of desert tortoise (Gopherus agassizii) burrow spoil and undisturbed surficial soils in California, 2023
Bighorn sheep (Ovis canadensis) were frequently photographed by wildlife cameras when they visited desert tortoise (Gopherus agassizii) burrows in the eastern San Bernardino Mountains near Palm Springs, California, USA (Mesa Windfarm). A previous study suggested that sheep may have been utilizing the excavated spoil material from burrows as a mineral lick. We aimed to test this...
