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.

Gross morphology, histology, and ultrastructure of the olfactory rosette of a critically endangered indicator species, the Delta Smelt, Hypomesus transpacificus [PDF]
Journal of Comparative Physiology A, 2021 AbstractThe 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 of their sensory anatomy is needed to advance our understanding of the sensory ecology of ...

Analysis of Limiting Factors Across the Life Cycle of Delta Smelt (Hypomesus transpacificus) [PDF]
Environmental Management, 2018 We developed a mechanistic life-cycle model derived from the elicitation of multiple factors influencing the success of individual life-stages of the imperiled delta smelt (Hypomesus transpacificus). We discuss the relevance of limiting factors in population ecology and problems with additive models in detecting them.

A pilot study of the performance of captive‐reared delta smelt Hypomesus transpacificus in a semi‐natural environment [PDF]
Journal of Fish Biology, 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 ...

Factors Controlling Calanoid Copepod Biomass and Distribution in the Upper San Francisco Estuary and Implications for Managing the Imperiled Delta Smelt (Hypomesus transpacificus) [PDF]
Environmental Management, 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.

Highly and Lowly Domesticated Endangered Fish From a Conservation Hatchery Diverge in Their Thermal Physiology, Transcriptome, and Methylome. [PDF]
Evol ApplABSTRACT Conservation hatcheries aim to produce fish for supplementation of wild populations, but hatchery environments may drive phenotypic divergence from wild fish. These diverged traits may have reduced fitness in the wild, which could compromise wild population sustainability and evolutionary potential, such as in response to climate change. Delta

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 ...
