To determine how a low cost oxygenation system affected survival of captively reared juvenile suckers, we introduced Passive Integrated Transponder (PIT) tagged juvenile suckers into three net pens in Upper Klamath Lake. The suckers originated from the U.S. Fish and Wildlife Service's Sucker Assisted Rearing Program in Klamath Falls, Oregon which rears suckers collected as larvae in Upper Klamath Lake including Lost River sucker (Deltistes luxatus), shortnose sucker (Chasmistes brevirostris), and Klamath largescale sucker (Catostomus synderi). Suckers were monitored continuously by PIT antennas. These data contain all remote detections from the PIT antennas, all physical captures, and the water quality data associated...

Ultra-low volumes of naled are applied by aircraft over rice fields and canals to reduce adult mosquito populations near Sacramento, California. Each summer, the pesticide is applied approximately 7-10 times between July and October. Naled and its major degradate (dichlorvos) were quantified in water, biofilm, and invertebrates following aerial applications. In 2020, samples were collected before the naled application season, after 3 rice field and 5 canal applications, and immediately after an application. In 2021, water and crayfish samples were collected before the naled application season, after 3 applications, and at intervals (1, 3, 5, and 7 days) following an application. A few opportunistic samples (including...

The dataset is composed of two tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) on the Eastern Erie Canal in New York. Environmental DNA using water samples and traditional fish surveys using benthic trawling, seining, and trapping were conducted twice annually at 12 sites on the Eastern Erie Canal between Oneida Lake and the Hudson River from 2016-2019. Study sites were selected to be approximately equidistant apart (~ 20 km) while also taking advantage of suitable access points. Within a study site, the exact areas that were sampled were often staggered by 500 m or occasionally more in order to find appropriate habitat for each gear type (i.e., wadable...

Macroinvertebrate and environmental data were collected annually in July-August in the year before dike removal (2009) and the first three years after dike removal (2010-2012) at the Nisqually River Delta, Washington, U.S.A. Data were collected along a gradient extending from the inner marsh edge to the delta front and spanning different types of habitat including marsh restored to tidal inundation by dike removal, previously restored marsh, undisturbed reference marsh, and tidal flats. Biological data comprised benthic macroinvertebrate species composition, abundance, and biomass. Environmental correlates included bed elevation; sediment grain size, organic content, and pH; and water column temperature, salinity,...

These data represent the measurements of length and mouth gape from large juvenile and adult wild-caught and small juvenile hatchery origin black carp, and the results of laboratory size preference trials with bivalve prey, specifically Corbicula clams. Wild-caught black carp ranged from 429-1580 mm total length, a larger range than measured in previous studies. Corbicula feeding trial data consist of the shell dimensions of each clam, survival, and the frequency which clams were engulfed by black carp.

Harmful algal blooms (HABs) have recently been observed in rivers, including the Illinois River in the Midwest United States. The Illinois River Basin has a history of eutrophication issues, primarily caused by the excessive loading of nitrogen and phosphorus from urban and agricultural sources. Recent events have seen the emergence of cyanobacterial harmful algal blooms in the area. This data release provides early warning indicator (EWI) metrics derived from a continuous chlorophyll concentration dataset obtained from seven water quality monitoring sites along the Illinois River. These metrics include the first-order autoregressive process (Ar1) and the standard deviation (SD) of chlorophyll, which serve as leading...
This dataset contains two separate sets two- and quasi-three-dimensional hydrodynamic model outputs from the Flow and Sediment Transport with Morphologic Evolution of CHannels (FaSTMECH) hydrodynamic model in the open-source binary Visualization Toolkit (VTK) format (https://vtk.org/). The first dataset set contains outputs from simulations of flow conditions of 348 cms as measured on July 1, 2019, during a larval drift experiment conducted on the Upper Missouri River near Wolf Point, MT. The second dataset contains hydrodynamic model outputs from simulations at the same site for flows in the range of 185-635 cms at increments of 30cms. Files can be opened using the open-source software program Paraview: (https://www.paraview.org/).
