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) (

Allozyme Analysis of Delta Smelt, Hypomesus transpacificus and Longfin Smelt, Spirinchus thaleichthys in the Sacramento-San Joaquin Estuary, California

Copeia, 1995
Two species of smelt (Osmeridae), Hypomesus transpacificus and Spirinchus thaleichthys, found in the Sacramento-San Joaquin estuary recently have declined in abundance, and H. transpacificus has been threatened by the introduction of nonnative Hypomesus nipponensis.

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
