Otolith-based comparisons of wild versus hatchery-origin delta smelt

Endangered Species Research
The rapid decline of California’s endangered delta smelt Hypomesus transpacificus has called for immediate and effective conservation actions. Since 2021, up to 92000 cultured delta smelt have been released annually into the Sacramento-San Joaquin River ...

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.

Initial Assessment of the Introduction of Spottail Shiner (Notropis hudsonius) and Delta Smelt (Hypomesus transpacificus) into Willard Bay Reservoir, Utah.

, 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.
