Linking Hydrodynamic Complexity to Delta Smelt (Hypomesus transpacificus) Distribution in the San Francisco Estuary, USA [PDF]
San Francisco Estuary and Watershed Science, 2016 doi: http://dx.doi.org/10.15447/sfews.2016v14iss1art3Long-term fish sampling data from the San Francisco Estuary were combined with detailed three-dimensional hydrodynamic modeling to investigate the relationship between historical fish catch and ...

Modification of the biological intercept model to account for ontogenetic effects in laboratory-reared delta smelt (Hypomesus transpacificus)* [PDF]
, 2007 We investigated age, growth, and ontogenetic effects on the proportionality of otolith size to fish size in laboratory-reared delta smelt (Hypomesus transpacificus) from the San Francisco Bay estuary. Delta smelt larvae were reared from hatching in laboratory mesocosms for 100 days.

Initial Assessment of the Introduction of Spottail Shiner (Notropis hudsonius) and Delta Smelt (Hypomesus transpacificus) into Willard Bay Reservoir, Utah. [PDF]
, 1984 Spottail shiner (Notropis hudsonius) and delta smelt (Hypomesus transpacificus) were introduced into Willard Reservoir to improve the forage base for walleye (Stizostedion vitreum vitreum) and black crappie (Pomoxis nigromaculatus). Spottail shiners were stocked in early spring in 1981, 1982, and 1983.

Developmental Staging and Salinity Tolerance in Embryos of the Delta Smelt, Hypomesus transpacificus. [PDF]
Aquaculture, 2019 Delta smelt (Hypomesus transpacificus) is a critically endangered species endemic to the San Francisco Bay Delta (SFBD). Important for the conservation of this species is understanding the physiological and ecological impacts contributing to their population decline, and current studies lack information on embryonic development.

Baxterdoi: http://dx.doi.org/10.15447/sfews.2014v12iss3art1The Delta Smelt, an endangered fish, has suffered a long-term decline in abundance, believed to result from, in part, to changes in the pelagic food web of the ...

A pilot study of the performance of captive-reared delta smelt Hypomesus transpacificus in a semi-natural environment. [PDF]
J Fish Biol, 2019 AbstractA captive breeding programme was developed in 2008 for delta smelt Hypomesus transpacificus in reaction to dramatic population decline over several decades. We took 526 sub‐adult captive‐reared delta smelt and cultured them for 200 days without providing artificial food or water quality management to assess their performance once released in ...

Time-varying flow-ecology relationships for an endangered fish population: Longfin Smelt in the San Francisco Estuary. [PDF]
Ecol ApplAbstract Major estuaries globally are experiencing fast‐paced changes in hydrology and ecosystem dynamics. However, connecting alteration of river flow regimes to estuarine fish population dynamics remains a challenge, partly due to the untested assumption that flow regimes, fish dynamics, and the resulting flow–ecology relationships are stationary (i ...

Floodplain inundation and lateral connectivity promote productivity in a managed river ecosystem. [PDF]
Ecol ApplAbstract River‐floodplain ecosystems near urban centers are heavily engineered for flood protection and water delivery, which has led to a loss of lateral hydrologic connectivity between rivers and their floodplains. This study has two objectives: (1) Does increased lateral connectivity resulting from floodplain inundation increase chlorophyll a ...

Factors Controlling Calanoid Copepod Biomass and Distribution in the Upper San Francisco Estuary and Implications for Managing the Imperiled Delta Smelt (Hypomesus transpacificus). [PDF]
Environ Manage, 2020 AbstractDelta smelt struggle to persist in a dramatically altered estuarine environment. Complex and incompletely understood relationships between food availability, environmental stressors, other components of the species’ habitat, and the abundance of delta smelt impede the effective management and recovery of the species.
