Conservation of Native Fishes of the San Francisco Estuary: Considerations for Artificial Propagation of Chinook Salmon, Delta Smelt, and Green Sturgeon

San Francisco Estuary and Watershed Science, 2011
Many native fishes in the San Francisco Estuary and its watersheds have reached all-time low abundances. Some of these declining species (e.g., Chinook salmon Oncorhynchus tschawytscha) have been under artificial propagation for decades. For others (e.g.,

Evaluation of a large-scale flow manipulation to the upper San Francisco Estuary: Response of habitat conditions for an endangered native fish

PLoS ONE, 2020
While flow is known to be a major driver of estuarine ecosystems, targeted flow manipulations are rare because tidal systems are extremely variable in space and time, and because the necessary infrastructure is rarely available.

Locating Little Larvae: Environmental DNA Methods Can Detect a Rare Fish Species Under Field Estuarine Conditions

Environmental DNA
Rare species are difficult to monitor using traditional methods, making them excellent candidates for environmental DNA (eDNA) monitoring. The larval life stages of Delta Smelt (Hypomesus transpacificus) and Longfin Smelt (Spirinchus thaleichthys) are ...

Integrative Assessments of Niche Dimensions and Multiple Stressor Effects on Endangered Delta Smelt (Hypomesus transpacificus). [PDF]

, 2015
This project investigated the ecological niche and multiple stressor scenarios in the endangered fish species Delta Smelt (Hypomesus transpacificus). Survival and physiological stress response were affected by turbidity, salinity and contaminants, and the role of these factors in the species decline was evaluated.

Abundance Trends, Distribution, and Habitat Associations of the Invasive Mississippi Silverside (Menidia audens) in the Sacramento–San Joaquin Delta, California, USA

San Francisco Estuary and Watershed Science, 2016
doi: http://dx.doi.org/10.15447/sfews.2016v14iss1art2Although many alien fish species have colonized the Sacramento–San Joaquin Delta (Delta), few are as pervasive and abundant as Mississippi Silversides (Menidia audens).

A Place to Call Home: A Synthesis of Delta Smelt Habitat in the Upper San Francisco Estuary

San Francisco Estuary and Watershed Science, 2013
We used a combination of published literature and field survey data to synthesize the available information about habitat use by delta smelt Hypomesus transpacificus, a declining native species in the San Francisco Estuary.
