Surf smelt accelerate usage of endogenous energy reserves under climate change.
PLoS ONE, 2022 Surf smelt (Hypomesus pretiosus) are ecologically critical forage fish in the North Pacific ecosystem. As obligate beach spawners, surf smelt embryos are exposed to wide-ranging marine and terrestrial environmental conditions. Despite this fact, very few

Ecosphere, Volume 17, Issue 3, March 2026.Abstract Consumptive use of freshwater is of concern in many estuarine ecosystems, and various frameworks have been used to prescribe environmental flows to benefit native species. However, few of these frameworks explicitly examine the potential trade‐offs between socioeconomic and conservation‐oriented values.

Environmental DNA, Volume 8, Issue 2, March/April 2026.We measured a positive linear relationship between eDNA concentration and abundance for larval Delta Smelt (Hypomesus transpacificus) with N = 1 larva exceeding the limit of detection for the novel qPCR assay. Field experiments quantified the probability of detection for eDNA sampling methods at known abundances and distances from source. ABSTRACT Rare

Functional Response of Protected Larval Stage Delta Smelt (Hypomesus transpacificus) [PDF]
, 2012 Delta smelt (Hypomesus transpacificus) is a protected slender-bodied fish endemic to the San Francisco Estuary. Smelt prey upon various zooplankton including the copepods such as Pseudodiaptomus forbesi.

The Content of Ca in the Muscle of a Teleost, Hypomesus olidus, in Relation to its Environment
NIPPON SUISAN GAKKAISHI, 1937 Of the two lakes, Hinuma and Kasumigaura, located close to the coast of the Ibaraki Prefecture, the former is much more subject to invasion of sea-water. The chemical analysis has shown (Table 2) that 0·922 mg. of Ca and 57·31 mg. af Cl are present on average in the water of Lake Hinuma, whereas 0·716 mg. of Ca and 2·178 mg. Cl are present in the water

The use of discriminate function analysis in the identification of two species of larval smelt, Spirinchus thaleichthys and Hypomesus T. transpacificus, in the Sacramento-San Joaquin estuary, California [PDF]
, 1977 The objectives of this study are to identify the larval forms of the two species of smelt, Spirinchus thaleichthys and Hypomesus transpacificus transpacificus, and to better describe their spawning times in the Sacramento-San Joaquin ...

Persistent Genetic Identification of Maternal Mitochondrial Lineage in Formalin Fixed Larval Delta Smelt (Hypomesus transpacificus) with Species-Specific qPCR [PDF]
Although formalin is commonly used as a preserving reagent for tissue specimens, the fixation process itself damages DNA, which can be detrimental to most downstream genetic analyses.

Migration behavior of PGCs and asymmetrical gonad formation in pond smelt Hypomesus nipponensis
The International Journal of Developmental Biology, 2017 In teleost fish, the gonad originates from primordial germ cells (PGCs) and somatic cells. However, it is not clear whether the final gonadal position is determined by anteroposterior and dextrosinistral differentiation of endodermal organs or by the distribution of PGCs.

Embryo Ecology of the Pacific Surf Smelt, Hypomesus pretiosus (Pisces: Osmeridae) [PDF]
, 1987 A study of the ecology of developing embryos of the Pacific surf smelt, Hypomesus pretiosus, was conducted. Embryos were maintained in the laboratory at 7.6, 12.1, and 17.6°C and the time to specific embryonic stages determined.
