Evaluating the impact of captive ancestry on the growth and survival of Delta Smelt in a captive environment

Aquaculture Reports
Delta Smelt Hypomesus transpacificus, is an endangered fish endemic to the California San Francisco Bay-Delta, USA. Extreme declines of the wild Delta Smelt population have prompted use of cultured fish to supplement the wild population since 2021 to ...

The health and condition responses of Delta Smelt to fasting: A time series experiment.

PLoS ONE, 2020
There is an extensive literature establishing, validating, and quantifying a wide range of responses of fishes to fasting. Our study complements this work by comparing fed and unfed treatments of hatchery-raised Delta Smelt (Hypomesus transpacificus)-an ...

Molecular Identification of the Nematode Eustrongylides ignotus in Mandarin Fish, Siniperca chuatsi

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Mandarin fish (Siniperca chuatsi) is a high‐value economic freshwater fish in China; however, the frequent occurrence of diseases threatens its production. To this end, we explored the impact of a nematode parasite newly found in the abdomen of mandarin fish collected from Pudong, Shanghai, China.

Spatially dynamic abundance patterns for a rare fish species

Ecosphere, Volume 16, Issue 7, July 2025.
Abstract Recovery of rare and imperiled species is often supported by targeting the dynamic drivers of abundance patterns. However, knowledge of these drivers can be obscured by challenges stemming from species detectability and autocorrelated data. Longfin Smelt (Spirinchus thaleichthys) in the San Francisco Bay‐Delta have become rare as the result of

Characterizing macroinvertebrate community composition and abundance in freshwater tidal wetlands of the Sacramento-San Joaquin Delta.

PLoS ONE, 2019
Restored tidal wetlands may provide important food web support for at-risk fish species in the Sacramento-San Joaquin Delta (Delta) of California, including Delta Smelt (Hypomesus transpacificus) and Chinook Salmon (Oncorhynchus tshawytscha).

Rapid CRISPR‐Cas13a genetic identification enables new opportunities for listed Chinook salmon management

Molecular Ecology Resources, Volume 25, Issue 5, July 2025.
Abstract Accurate taxonomic identification is foundational for effective species monitoring and management. When visual identifications are infeasible or inaccurate, genetic approaches provide a reliable alternative. However, these approaches are sometimes less viable (e.g., need for near real‐time results, remote locations, funding concerns, molecular

Evaluation and Interpretation of Genetic Effective Population Size of Delta Smelt from 2011–2014

San Francisco Estuary and Watershed Science, 2017
https://doi.org/10.15447/sfews.2017v15iss2art5Delta Smelt have collapsed demographically, but little is known about their current genetic status. We used 12 microsatellite loci to evaluate two measures of the effective population size (Ne) of Delta ...

The Future of Pathogen Detection in Aquaculture: Miniature Labs, Field‐Compatible Assays, environmental DNA and RNA, CRISPR and Metatranscriptomics

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Inland recirculating aquaculture is a thriving food industry providing sustainable and locally sourced high‐quality protein. However, its expansion is accompanied by emerging challenges regarding the spread of pathogens and diseases. Detection and management of pathogens in aquaculture remain underdeveloped compared to other animal farming ...

Single generation epigenetic change in captivity and reinforcement in subsequent generations in a delta smelt (Hypomesus transpacificus) conservation hatchery

Molecular Ecology
AbstractA refugial population of the endangered delta smelt (Hypomesus transpacificus) has been maintained at the Fish Conservation and Culture Laboratory (FCCL) at UC Davis since 2008. Despite intense genetic management, fitness differences between wild and cultured fish have been observed at the FCCL.

Sample Design-based Methodology for Estimating Delta Smelt Abundance

San Francisco Estuary and Watershed Science, 2008
A sample design-based procedure for estimating pre-adult and adult delta smelt abundance is described. Using data from midwater trawl surveys taken during the months of September, October, November, and December for the years 1990 through 2006 and ...
