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.

Toxics, 2021 Salinity can interact with organic compounds and modulate their toxicity. Studies have shown that the fraction of pyrethroid insecticides in the aqueous phase increases with increasing salinity, potentially increasing the risk of exposure for aquatic ...

San Francisco Estuary and Watershed Science, 2023 For many imperiled species, comparisons between wild and cultured populations are invaluable for informing conservation measures, though opportunities to do so may be rare. In this study, we asked whether spawning between and among wild and cultured Delta Smelt varies in terms of behavior or resulting egg fertilization success.

Identifying Environmental Factors Limiting Recovery of an Imperiled Estuarine Fish
Frontiers in Ecology and Evolution, 2022 Correctly identifying the environmental factors that limit population growth and recovery of imperiled species is an essential element of any targeted conservation program.

Delta Smelt (Hypomesus transpacificus) Exhibit Wide Variation in Spawning Behavior: An Investigation of Substrate Type, Diel Timing, and Participants [PDF]
Estuaries and Coasts, 2021 AbstractStudies of cultured populations can be invaluable to the conservation of imperiled species for which little is known and whose very low abundance in the wild can preclude studies with robust sample sizes. For example, in endangered delta smelt (Hypomesus transpacificus), conservation measures developed to mitigate population decline are ...

Experimental validation of otolith-based age and growth reconstructions across multiple life stages of a critically endangered estuarine fish [PDF]
PeerJ, 2021 Background The application of otolith-based tools to inform the management and conservation of fishes first requires taxon- and stage-specific validation.
