This data release includes physical and chemical characteristics of field collected sediment and soil samples in Missouri representing potential sediment/soil that may enter the water column during construction related activities. Three samples were collected, including Spring River sediment, Osage River bank soil and Columbia crushed limestone. The impacts of increased suspended solid level due to the three samples on early-stage freshwater mussels were examined using three freshwater mussel species, including Fatmucket (Lampsilis siliquoidea), Arkansas Brokenray (Lampsilis reeveiana), and Washboard (Megalonaias nervosa). Specifically, toxicity endpoints including survival, biomass, and growth of juveniles were...

Survival, behavior, reproduction, morphometric measurements, and tissue analyses of crayfish, mussels, and fish from acute toxicity tests with pyrethroid pesticides. Exposure and recovery water quality data are also included for quality assurance purposes.
In order to estimate the costs of chemical control of non-indigenous crayfish versus the cost of manual inspection of fish hatchery shipments a cost analysis was performed. The data includes ranking the likelihood of missing non-indigenous crayfish and effects on fish of handling during manual searches and the effects on fish during chemical exposure. The data also includes estimates of the time, staff, and salary requirements and cost of materials for each approach.
We determined the acute toxicity of four wildland fire retardants (Phos-Chek 259-Fx, Phos-Chek MVP-Fx, and Phos-Chek LC-95A-Fx, and Phos-Chek LC-95A-R) to two life stages (swim-up fry and young juveniles) of rainbow trout in standardized hard and soft water. The measure of acute toxicity was expressed as both the 96-hour median lethal concentration (96-h LC50, based on mortality) and 96-h median effective concentration (EC50, based on mortality, plus loss of equilibrium and immobilization), which are statistically derived concentrations expected to kill or kill and severely impair, respectively, 50 percent of the test fish in 96 hours. This data set includes the concentration-response data at 24, 48, 72, and 96...
