A Qualitative Comparison of Spawning Behavior Between Cultured and Wild Delta Smelt (Hypomesus transpacificus)

San Francisco Estuary and Watershed Science, 2023
For many imperiled species, comparisons between wild and cultured populations are invaluable for informing conservation measures, though opportunities to do so may be rare. In this study, we asked whether spawning between and among wild and cultured Delta Smelt varies in terms of behavior or resulting egg fertilization success.

Physiological effects of salinity on Delta Smelt, Hypomesus transpacificus

Fish Physiology and Biochemistry, 2015
Abiotic factors like salinity are relevant to survival of pelagic fishes of the San Francisco Bay Estuary. We tested the effects of 4 parts per thousand (ppt) salinity increases on Delta Smelt (DS) in a laboratory experiment simulating salinity increases that might occur around the low-salinity zone (LSZ) (

TaqMan assays for the genetic identification of delta smelt (Hypomesus transpacificus) and wakasagi smelt (Hypomesus nipponensis)

Molecular Ecology Resources, 2011
AbstractWe have developed species‐specific TaqMan assays for two California fish species, the threatened delta smelt (Hypomesus transpacificus) and the introduced wakasagi smelt (Hypomesus nipponensis). The assays are capable of correctly identifying each species with 100% accuracy, with no cross‐species amplification.

Sublethal responses to ammonia exposure in the endangered delta smelt; Hypomesus transpacificus (Fam. Osmeridae)

Aquatic Toxicology, 2011
The delta smelt (Hypomesus transpacificus) is an endangered pelagic fish species endemic to the Sacramento-San Joaquin Estuary in Northern California, which acts as an indicator of ecosystem health in its habitat range. Interrogative tools are required to successfully monitor effects of contaminants upon the delta smelt, and to research potential ...

Assessing oocyte development and maturation in the threatened Delta Smelt, Hypomesus transpacificus

Environmental Biology of Fishes, 2016
Delta Smelt is a pelagic annual fish species endemic to the San Francisco Estuary, which is protected under U.S. Federal and California State Endangered Acts. In this study we established criteria for scoring Delta Smelt maturity based on the histological features in ovary, as well as measurements of the female sex hormone 17β-estradiol (E2) from liver

A Covered Cod-End and Tow-Path Evaluation of Midwater Trawl Gear Efficiency for Catching Delta Smelt (Hypomesus transpacificus) [PDF]

San Francisco Estuary and Watershed Science, 2017
https://doi.org/10.15447/sfews.2017v15iss4art3For nearly 50 years, the California Department of Fish and Wildlife has used a midwater trawl to intensively monitor fish populations in the San Francisco Estuary during the fall, sampling over 100 locations each month.
