Sample Design-based Methodology for Estimating Delta Smelt Abundance [PDF]
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 ...

Modeling Delta Smelt Distribution for Hypothesized Swimming Behaviors [PDF]
San Francisco Estuary and Watershed Science, 2021 Delta Smelt, Hypomesus transpacificus, is an endangered pelagic fish native to the San Francisco Estuary. The distribution of Delta Smelt in the estuary shifts landward from low-salinity habitat to freshwater habitat before spawning. This spawning migration often coincides with the first substantial freshwater inflow to the estuary during winter.

Delta Smelt and Water Politics in California
Fisheries, 2018 Abstract The Delta Smelt Hypomesus transpacificus is a small translucent fish that lives in the heart of California's water distribution system. It is an endemic species that is on verge of extinction, largely because it is in direct competition with people for water.

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.

Vital dye immersion evaluations with juvenile delta smelt
Aquaculture, Fish and Fisheries, 2023 Immersion‐based vital dyes were tested as a marking method for use in larval smelt mark–recapture studies. We assessed five fluorescent dyes as a mark for juvenile osmerids: 4‐Di‐1‐ASP, BODIPY FL C12, BODIPY 505/515, Nile red, and calcein.

A novel and versatile flash-freezing approach for evaluating the health of Delta Smelt [PDF]
Aquatic Toxicology, 2016 A common approach used to assess environmental impacts in aquatic environments is to measure indicators of stress (biomarkers) and condition of fish within ecosystems. Particularly in estuarine ecosystems with multiple stressors, it is often desirable to quantify a suite of biological endpoints that (1) reflect fish condition at several levels of ...
