Salinity and diel timing affect group structure in Delta Smelt
Aquaculture, Fish and Fisheries, 2023 Delta Smelt are thought to be on the precipice of extinction. Studies that examine how this endangered species responds to environmental change are important to informing conservation efforts.

Vital dye immersion evaluations with juvenile delta smelt
Aquaculture, Fish and Fisheries, 2023 Immersion‐based vital dyes were tested as a marking method for use in larval smelt mark–recapture studies. We assessed five fluorescent dyes as a mark for juvenile osmerids: 4‐Di‐1‐ASP, BODIPY FL C12, BODIPY 505/515, Nile red, and calcein.

Modeling Delta Smelt Losses at the South Delta Export Facilities [PDF]
San Francisco Estuary and Watershed Science, 2011 I previously estimated proportional losses of delta smelt to the water export facilities in the south Delta (Kimmerer 2008). This note is in response to Miller (2010), who disputes these estimated losses on several grounds.

Sample Design-based Methodology for Estimating Delta Smelt Abundance [PDF]
San Francisco Estuary and Watershed Science, 2008 A sample design-based procedure for estimating pre-adult and adult delta smelt abundance is described. Using data from midwater trawl surveys taken during the months of September, October, November, and December for the years 1990 through 2006 and ...

The health and condition responses of Delta Smelt to fasting: A time series experiment. [PDF]
PLoS One, 2020 There is an extensive literature establishing, validating, and quantifying a wide range of responses of fishes to fasting. Our study complements this work by comparing fed and unfed treatments of hatchery-raised Delta Smelt (Hypomesus transpacificus)-an imperiled fish that is endemic to the San Francisco Estuary and its tributaries in California, USA ...
