Spawning behaviour between endemic delta smelt (Hypomesus transpacificus) and non‐native Wakasagi (H. nipponensis) in the San Francisco estuary

open access: yesJournal of Fish Biology, EarlyView.
Abstract In the San Francisco Estuary, non‐native Wakasagi Hypomesus nipponensis hybridize with endemic and endangered Delta Smelt H. transpacificus, and all wild‐caught hybrids have a maternal Wakasagi parent. However, the mechanisms that facilitate or impede hybridization and explain sex‐biased hybrid asymmetry between these two species remain ...

Size, fecundity and condition factor changes in endangered delta smelt Hypomesus transpacificus over 10 generations in captivity

open access: yesAquaculture, Fish and Fisheries, 2023
The once abundant delta smelt Hypomesus transpacificus is now on the verge of extinction. At the UC Davis Fish Conservation and Culture Laboratory, a refuge population has been maintained since 2008 as a safeguard against extinction and to breed and ...

Fish assemblage at a newly restored tidal wetland reflects surrounding waterways in the Sacramento‐San Joaquin Delta

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction We studied the response of fish assemblages, water quality, and plankton following the completion of 700 acres of a 1184‐acre tidal restoration project (Dutch Slough Tidal Restoration; DSTR) in a system degraded by water diversions, channelization, non‐native species, and wetland loss.

Gross morphology, histology, and ultrastructure of the olfactory rosette of a critically endangered indicator species, the Delta Smelt, Hypomesus transpacificus [PDF]

open access: yes, 2021
The Delta Smelt (Hypomesus transpacificus) is a small, semi-anadromous fish native to the San Francisco Bay-Delta Estuary and has been declared as critically endangered. Their olfactory biology, in particular, is poorly understood and a basic description

Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Silverside gold mine? Restored tidal habitats host abundant invasive fishes in a novel California marsh (U.S.A.)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...

Transcriptional flexibility during thermal challenge corresponds with expanded thermal tolerance in an invasive compared to native fish

open access: yesEvolutionary Applications, 2021
Capacity to cope with warming temperatures is a key determining factor of species' persistence under global climate change. Many successful invasive species have heightened thermal tolerance relative to their native counterparts, which may provide ...

Delta Smelt stress responses during fish salvage at the John E. Skinner Delta Fish Protective Facility, California

open access: yesCalifornia Fish and Wildlife Journal, 2023
The John E. Skinner Delta Fish Protective Facility (Skinner Fish Facility) diverts entrained fish from the State Water Project’s pumping facilities in the southern Sacramento-San Joaquin Delta (the Delta) and transports them via tanker trucks away from ...

Ecological Studies of the Pond Smelt, Hypomesus olidns (PALLAS)-II

open access: yesNIPPON SUISAN GAKKAISHI, 1953
The scale of pond smelt, Hypomesus olidus (PALLAS), shows no definite annual-ring in such a manner as the scale of salmon or herring. Two different zones, one of which grows in summer and the other in winter, are recognized on the scale of the fish in Lake Kasumigaura by F. MATSUZAKI (1916), while, according to H.

Global Burden of Clinostomum complanatum in Freshwater Fish: A Systematic Review and Meta‐Analysis of Prevalence and Pathological Effect

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Clinostomum complanatum infection is a trematode parasite infecting diverse freshwater fish hosts, causing pathological damage and economic losses. Despite its veterinary and public health importance, its global burden remains insufficiently quantified. This study aimed to assess the global burden of C.
