Reproductive strategy of Delta Smelt Hypomesus transpacificus and impacts of drought on reproductive performance. [PDF]

PLoS ONE, 2022
Understanding reproductive biology and performance of fish is essential to formulate effective conservation and management programs. Here, we studied reproductive strategies of female Delta Smelt Hypomesus transpacificus, an endangered fish species in ...

Temperature and salinity preferences of endangered Delta Smelt (Hypomesus transpacificus, Actinopterygii, Osmeridae) [PDF]

Scientific Reports, 2022
Temperature and salinity often define the distributions of aquatic organisms. This is at least partially true for Delta Smelt, an imperiled species endemic to the upper San Francisco Estuary.

Captive-reared Delta Smelt (Hypomesus transpacificus) exhibit high survival in natural conditions using in situ enclosures. [PDF]

PLoS ONE, 2023
Conservation of endangered fishes commonly includes captive breeding, applied research, and management. Since 1996, a captive breeding program has existed for the federally threatened and California endangered Delta Smelt Hypomesus transpacificus, an ...

Size, fecundity and condition factor changes in endangered delta smelt Hypomesus transpacificus over 10 generations in captivity

Aquaculture, Fish and Fisheries, 2023
The once abundant delta smelt Hypomesus transpacificus is now on the verge of extinction. At the UC Davis Fish Conservation and Culture Laboratory, a refuge population has been maintained since 2008 as a safeguard against extinction and to breed and ...

Chromosome-Level Genome Assembly of Protosalanx chinensis and Response to Air Exposure Stress [PDF]

Biology, 2023
Protosalanx chinensis is a suitable particular species for genetic studies on nearly scaleless skin, transparency and high sensitivity to hypoxia stress. Here, we generated a high-quality chromosome-level de novo assembly of P. chinensis.

Visual, spectral, and microchemical quantification of crystalline anomalies in otoliths of wild and cultured delta smelt [PDF]

Scientific Reports, 2022
Developmental abnormalities in otoliths can impact growth and survival in teleost fishes. Here, we quantified the frequency and severity of developmental anomalies in otoliths of delta smelt (Hypomesus transpacificus), a critically endangered estuarine ...

Time-varying flow-ecology relationships for an endangered fish population: Longfin Smelt in the San Francisco Estuary. [PDF]

Ecol Appl
Abstract 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 ...
