Liver Glycogen as a Sensitive Indicator of Food Limitation in Delta Smelt
Abstract Assessing habitat quality is a major goal of conservationists and restoration practitioners, but to associate habitat quality with biomarkers of vagile animals, the biomarkers must respond rapidly. Here, we identified a biomarker capable of rapidly detecting food limitation in the imperiled Delta Smelt (

Histopathological assessment of seven year-classes of Delta Smelt
The Delta Smelt (Hypomesus transpacificus) is an imperiled, annual fish endemic to the Sacramento-San Joaquin Delta and San Francisco Estuary. This study examined the severity and prevalence of liver and gill lesions of juvenile through adult Delta Smelt from 2011 through 2017 collected from five regions throughout its habitat (n = 1,053).

Wakasagi in the San Francisco Bay–Delta Watershed: Comparative Trends in Distribution and Life-History Traits with Native Delta Smelt [PDF]
Intentional introductions of non-native fishes can have severe consequences on native communities. Wakasagi (Hypomesus nipponensis, referred to as Japanese Pond Smelt) are native to Japan and were once separated from their non-native congener the ...

Foraging and metabolic consequences of semi-anadromy for an endangered estuarine fish. [PDF]
Diadromy affords fish access to productive ecosystems, increasing growth and ultimately fitness, but it is unclear whether these advantages persist for species migrating within highly altered habitat.

Understanding the Extent of Hyperactivity and Related Behavioral Alterations in Delta Smelt and Longfin Smelt [PDF]
Agricultural and urban contaminants enter aquatic environments at concentrations that can affect a variety of sublethal endpoints, including organismal behavior, which can in turn lead to impacts at the population level. The San Francisco Bay Delta (SFBD)

A Qualitative Comparison of Spawning Behavior between Cultured and Wild Delta Smelt (Hypomesus transpacificus) [PDF]
For many imperiled species, comparisons between wild and cultured populations are invaluable for informing conservation measures, though opportunities to do so may be rare.

Assessing captive spawning strategies for supplementation production of Delta Smelt
Abstract Objective To support the declining wild population of Delta Smelt, a conservation hatchery has expanded its mission from maintaining a backup population as insurance against extinction to also producing fish for release into the wild.
