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 ...

Locating Little Larvae: Environmental DNA Methods Can Detect a Rare Fish Species Under Field Estuarine Conditions

Environmental DNA
Rare species are difficult to monitor using traditional methods, making them excellent candidates for environmental DNA (eDNA) monitoring. The larval life stages of Delta Smelt (Hypomesus transpacificus) and Longfin Smelt (Spirinchus thaleichthys) are ...

Functional Response of Protected Larval Stage Delta Smelt (Hypomesus transpacificus) [PDF]

, 2012
Delta smelt (Hypomesus transpacificus) is a protected slender-bodied fish endemic to the San Francisco Estuary. Smelt prey upon various zooplankton including the copepods such as Pseudodiaptomus forbesi.

Eastward Migration or Marshward Dispersal: Exercising Survey Data to Elicit an Understanding of Seasonal Movement of Delta Smelt

San Francisco Estuary and Watershed Science, 2013
Differing and confounding understandings of the seasonal movements of the delta smelt (Hypomesus transpacificus) in the San Francisco Estuary persist nearly 2 decades after its listing as threatened under the federal and state endangered species acts.
