Longfin Smelt,
San Francisco Bay-Delta,
This data set includes taxonomic data for zooplankton, larval fish, and phytoplankton sampled in Little Holland Tract and Liberty Island Conservation Bank, in the northern Sacramento-San Joaquin River Delta, California. Zooplankton and larval fish were collected with target specific trawl nets and phytoplankton was collected from water grabs. This data release includes all measured environmental parameters.
This dataset is a compilation of Longfin Smelt observations from multiple sources, including research institutions and museums, and local, state, and federal fisheries agencies.

This data set includes count, location, and ancillary habitat data for fishes sampled in adjacent reaches of Georgiana Slough, Sacramento River, and Steamboat Slough in the northern Sacramento-San Joaquin Delta. It also includes data on the stomach contents of selected individual black basses (Micropterus). Fishes were sampled by boat electrofishing from approximately January-May, 2020-2022, plus gillnetting in 2020. Samples were collected under a stratified random sampling design. Gillnetting involved short duration (~60 minute) sets of monofilament experimental gill nets. Boat electrofishing involved either single or repeated passes along an individual 300 m shoreline transect. Stomach contents data are from fishes...

This data release includes field data for fishes sampled through mid-water trawls and otter trawl methods from Suisun Bay, California to the mouth of the Sacramento River. These data were collected from the months of September through October in 2022 and 2023 as a part of a multi-year study of Suisun Dredging and Fish Distribution (SDFD). This data release includes quantitative data on collected fish taxa focused on habitat differences between shipping channels and shoals. Sampling was done using short duration (~15 minute) trawls alongside associated water quality sample and Acoustic Doppler Current Profiler (ADCP) data collected at variable locations, depths, times, and currents. First release: May 26,2023 Revised:...

This data set contains information on zooplankton and associated environmental parameters for sampling conducted in the San Joaquin River and False River near their confluence at Jersey Point (Contra Costa County, California), during February-March, 2016. Macrozooplankton were sampled with vertical tows (bottom to surface) of a 50 cm-diameter conical plankton net that was 150cm long with 102µm mesh. Samples were preserved in the field in 10% formalin for laboratory processing that was conducted by a contractor (EcoAnalysts, Inc).

This is the data release for gillnet data from a 2016-18 USGS Tidal Wetlands Study and a 2010-11 Sacramento Splittail Study targeting fish in the upper San Francisco Estuary and Sacramento-San Joaquin Delta. This data was used to analyze selectivity parameters of five gillnet mesh sizes (38.1, 50.8, 63.5, 76.2, 88.9 mm) on 15 fish species of the upper San Francisco Estuary and Sacramento-San Joaquin Delta (Striped Bass (Morone saxatilis), Sacramento Splittail (Pogonichthys macrolepidotus), White Catfish (Ameiurus catus), Redear Sunfish (Lepomis microlophus), Sacramento Pikeminnow (Ptychocheilus grandis), Tule Perch (Hysterocarpus traskii), Jacksmelt (Atherinopsis californiensis), Sacramento Sucker (Catostomus occidentalis),...

This data set contains information on zooplankton and associated environmental parameters for sampling conducted in California's northern Sacramento-San Joaquin Delta between May 2016 and April 2018. Macrozooplankton were sampled with horizontal tows (water surface) of a 50 cm-diameter conical plankton net that was 150cm long with 102µm mesh. Samples were preserved in the field in 10% formalin for laboratory processing that was conducted by a contractor (EcoAnalysts, Inc).
