Egg thiamine content, length, weight and survival of steelhead (Oncorhynchus mykiss) exposed to three methods of experimental thiamine supplementation in 2022 and egg thiamine content from three Oregon hatcheries in 2019 Egg thiamine content, length, weight and survival of steelhead (Oncorhynchus mykiss) exposed to three methods of experimental thiamine supplementation in 2022 and egg thiamine content from three Oregon hatcheries in 2019
Early rearing of steelhead (Oncorhynchus mykiss) in Oregon hatcheries is often problematic; fry can become emaciated and die during the period between hatch and first feed. Thiamine (vitamin B1) deficiency has caused early mortality in salmonids; however, thiamine status of Oregon’s anadromous steelhead populations is currently unknown. We sampled eggs of 7-10 females during spawning...
Observations of survival and hatch of developing pallid sturgeon embryos in relation to experimental substrate and sediment cover Observations of survival and hatch of developing pallid sturgeon embryos in relation to experimental substrate and sediment cover
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...
Grass Carp detections via stationary receivers and manual tracking on Truman Reservoir, MO, January 2017 to October 2019 Grass Carp detections via stationary receivers and manual tracking on Truman Reservoir, MO, January 2017 to October 2019
Diploid and triploid Grass Carp (Ctenopharyngodon Idella) tagged with acoustic transmitters were observed in Truman Reservoir, Missouri from January 2017 to October 2019 to determine longitudinal movements potentially associated with spawning. Passive acoustic receivers were deployed throughout the reservoir and its tributaries to monitor fish movements as they traversed up and...
Capture method, habitat, length, and diet items consumed by wild-caught black carp (Mylopharyngodon piceus) in the Mississippi River Basin, 2017-2019 Capture method, habitat, length, and diet items consumed by wild-caught black carp (Mylopharyngodon piceus) in the Mississippi River Basin, 2017-2019
An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught black carp, based on the examination of gut contents from fish that were collected in the lower Mississippi River drainage of the U.S.
Invertebrates enumerated from the diets of larval pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (S. platorynchus) in the Upper Missouri River, Montana and North Dakota in 2019 Invertebrates enumerated from the diets of larval pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (S. platorynchus) in the Upper Missouri River, Montana and North Dakota in 2019
An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught larval pallid sturgeon and larval shovelnose sturgeon, based on the examination of gut contents from fish that were collected in the Upper Missouri River drainage of the U.S.
Thiaminase activity measurements in whole zebrafish Thiaminase activity measurements in whole zebrafish
Data describe results of a set of laboratory experiments using a previously described quantitative thiaminase I activity assay to test the thiaminase activity of whole zebrafish homogenates. Parameters described include the thiaminase activity data, dilution factors, incubation time, and tissue weight assayed. Experiments were conducted at the USGS Columbia Environmental Research Center...
Stream water chemistry and benthic macroinvertebrate data from the North Fork Clear Creek and Clear Creek, Colorado, USA, from 2011-2019, before and after acid mine drainage treatment Stream water chemistry and benthic macroinvertebrate data from the North Fork Clear Creek and Clear Creek, Colorado, USA, from 2011-2019, before and after acid mine drainage treatment
Stream water chemistry and benthic macroinvertebrate data collected in the North Fork of Clear Creek and Clear Creek, CO, USA before and after the diversion and treatment of acid mine drainage by a high-density sludge lime process water treatment plant. Stream water chemistry and benthic macroinvertebrate samples were collected from November 2011 through October 2019 at 6 sites located...
Pesticide residues in passive samplers and bee tissue from Conservation Reserve Program fields across an agricultural gradient in eastern Iowa, USA, 2019 (ver 2.0, October 2023) Pesticide residues in passive samplers and bee tissue from Conservation Reserve Program fields across an agricultural gradient in eastern Iowa, USA, 2019 (ver 2.0, October 2023)
This data release includes sampling location, pesticide concentrations in passive samplers (silicone bands) and bees foraging in Conservation Reserve Program fields. Sampling took place during July and August of 2019. Fields were located on private land managed for the U.S. Department of Agriculture Conservation Reserve Program in eastern central Iowa, U.S.A.
Quantitation of estrogens in water, alone and in combination with atrazine, using two chemically-activated luciferase expression, CALUX, bioassays and quadrupole-time of flight ultraperformance liquid chromatography/mass spectrometry, UPLC-MS Quantitation of estrogens in water, alone and in combination with atrazine, using two chemically-activated luciferase expression, CALUX, bioassays and quadrupole-time of flight ultraperformance liquid chromatography/mass spectrometry, UPLC-MS
This data describes the relative luminescence units and relative fluorescence units of lysates of two estrogen responsive chemically-activated luciferase expression human breast VM7Luc4E2 and VM7LucERbc9 cells which were exposed for 24 hours to estrone and 17beta-estradiol dilutions alone and in mixture with atrazine or water extracts collected from dilutor tanks during a fish exposure...
Water chemistry and fish metrics data for adult largemouth bass exposed in outdoor ponds to 17alpha-ethinylestradiol or an estrone-atrazine mixture Water chemistry and fish metrics data for adult largemouth bass exposed in outdoor ponds to 17alpha-ethinylestradiol or an estrone-atrazine mixture
Physiological endpoints observed in adult largemouth bass in response to an EE2 (17 alpha-ethinylestradiol) or mixture of estrone and atrazine exposure under laboratory pond conditions. Also included are water quality and chemical concentration data. Adult LMB were exposed in outdoor pond mesocosms from post-spawning to early gonad recrudescence to either EE2 (2.4 nanograms per liter)...
