Preliminary data on survival of Neocloeon triangulifer in sodium chloride bioassays fed differently aged diatoms Preliminary data on survival of Neocloeon triangulifer in sodium chloride bioassays fed differently aged diatoms
This data set includes mortality data from acute toxicity tests with aquatic larvae of the mayfly, Neocloeon triangulifer, exposed to sodium chloride. Two separate tests were conducted and fed diatom diets that were either 7-days-old or 13-days-old.
Survival of early instar mayflies (Neocloeon triangulifer) exposed to mixtures of major ion salts Survival of early instar mayflies (Neocloeon triangulifer) exposed to mixtures of major ion salts
This data set consists of 96-hour survival of the mayfly Neocloeon triangulifer exposed to a variety of major ion (sodium, potassium, calcium, magnesium, chloride, sulfate, bicarbonate) single salts, binary, and trinary mixtures, gluconate salts, and the organic molecule D-mannitol. Mayflies were less than 24-hours old at the beginning of tests. Mixtures consisted of pairs with either...
Pallid Sturgeon (Scaphirhynchus albus) Free Embryo Drift and Dispersal Experiment Associated with the Fort Peck Dam Flow Test in the Upper Missouri River, Montana, June 2024 Pallid Sturgeon (Scaphirhynchus albus) Free Embryo Drift and Dispersal Experiment Associated with the Fort Peck Dam Flow Test in the Upper Missouri River, Montana, June 2024
The data set contains sampling and catch data associated with an experiment to examine dispersal and short-term survival of endangered pallid sturgeon (Scaphirhynchus albus) free embryos in the Missouri River of eastern Montana. The experiment was conducted as part of a flow test from Fort Peck Dam, when warm surface water from Fort Peck reservoir was released over the spillway to...
Acute toxicity of nine critical elements to Hyalella azteca, Lampsilis siliquoidea, Lymnaea stagnalis, Neocloeon triangulifer, and Pimephales promelas with bioaccumulation data of three elements in Lymnaea stagnalis Acute toxicity of nine critical elements to Hyalella azteca, Lampsilis siliquoidea, Lymnaea stagnalis, Neocloeon triangulifer, and Pimephales promelas with bioaccumulation data of three elements in Lymnaea stagnalis
We conducted nineteen acute toxicity assays to address knowledge gaps associated with nine critical elements: cerium (Ce), cobalt (Co), indium (In), lanthanum (La), lithium (Li), neodymium (Nd), osmium (Os), platinum (Pt), and praseodymium (Pr). Acute aquatic exposures of these elements were conducted with five organisms: an amphipod (Hyalella azteca), a mussel (Lampsilis siliquoidea), a...
Effects of hypoxic exposure on survival of larval grass carp (Ctenopharyngodon idella) Effects of hypoxic exposure on survival of larval grass carp (Ctenopharyngodon idella)
We determined the effects of hypoxia exposure on grass carp larvae survival within certain developmental periods. Our goal was to establish a baseline lethal DO concentration based on both time of exposure and water temperature. In 2023 we used 6 different low dissolved oxygen concentrations (0.2, 0.4, 0.6, 0.8, 1.0 and 1.2 mg/L plus a control of 7.0 mg/L) to test survival during short...
Per- and polyfluoroalkyl substances (PFAS) measured in the coastal waters around Oahu, Hawai'i in 2019 and 2020 using passive samplers Per- and polyfluoroalkyl substances (PFAS) measured in the coastal waters around Oahu, Hawai'i in 2019 and 2020 using passive samplers
Concentrations of a group of per- and polyfluoroalkyl substances (PFAS) were measured in coastal waters around the island of Oahu, Hawai'i in 2019 and 2020 to provide a measure of exposure to resident fish species commonly harvested for human consumption. These contaminants were sampled using the polar organic chemical integrative sampler (POCIS) which allows for the determination of the...
Survival of juvenile mussels (Lampsilis siliquoidea) exposed to 6PPD and transformation products Survival of juvenile mussels (Lampsilis siliquoidea) exposed to 6PPD and transformation products
This data set includes mortality data from acute toxicity tests with juveniles of the mussel, Lampsilis siliquoidea exposed to 6PPD and 6PPDQ. Concurrently collected analytical chemistry and general water quality measurements are included.
Detection and quantification of 6PPD-quinone in small mouth bass and whole-body coho salmon fry using two sample preparation methods, accelerated solvent extraction and sonication with centrifugation extraction Detection and quantification of 6PPD-quinone in small mouth bass and whole-body coho salmon fry using two sample preparation methods, accelerated solvent extraction and sonication with centrifugation extraction
Concentrations of 6PPD-quinone, a primary transformation product of the rubber tire additive 6PPD, were measured in small mouth bass that were not exposed to 6PPD-quinone and used as quality control fish matrix for method optimization and in whole-body coho salmon fry that were exposed to known water concentrations of 6PPD-quinone during 96-hour acute toxicity exposures. Two different...
Data supporting the validation of First Annulus of Grass Carp Ctenopharyngodon idella and Silver Carp Hypophthalmichthys molitrix Data supporting the validation of First Annulus of Grass Carp Ctenopharyngodon idella and Silver Carp Hypophthalmichthys molitrix
A total of 83 Grass Carp and 92 Silver Carp were collected monthly from stocked ponds at Columbia Environmental Research Center. Length, weight, and collection date were recorded. The dorsal-fin rays and lapilli otoliths were collected from these specimens for the purpose of aging. An additional set of dorsal-fin rays and lapilli otoliths from Grass Carp collected in Truman Reservoir...
Upper Missouri River Velocity Data in Support of Fort Peck Test Flow larval release, June 2024 Upper Missouri River Velocity Data in Support of Fort Peck Test Flow larval release, June 2024
Flows at Fort Peck Dam, Montana, were modified in 2024 to include additions of warm epilimnetic reservoir releases over the spillway of the dam as part of a series of flow tests to improve habitat conditions in the Upper Missouri River for pallid sturgeon (Scaphirhynchus albus). We measured velocity and discharge on June 22 and June 23 in the Upper Missouri River and Fort Peck Dam...
Survival, neonate counts, and water quality measurements in controlled exposures to long-term wildland fire retardants to Ceriodaphnia dubia Survival, neonate counts, and water quality measurements in controlled exposures to long-term wildland fire retardants to Ceriodaphnia dubia
We investigated the survival and reproductive success of Ceriodaphnia dubia that were exposed to a concentration series of four current-use fire retardants (Phos-Chek 259-Fx Phos-Chek MVP-Fx, Phos-Chek LC95A-Fx, and Phos-Chek LC95A-R) to determine if exposure duration and concentration of the product altered the survival of C. dubia and the number of neonates produced by C. dubia. We...
