Characterization of Spawning Behavior in Cultured Delta Smelt [PDF]

open access: yesNorth American Journal of Aquaculture, 2021
Abstract We examined cultured Delta Smelt Hypomesus transpacificus under laboratory settings to provide the first formal characterization of spawning behavior, which included the quantification of participants and diel spawning patterns.

Delta Smelt stress responses during fish salvage at the John E. Skinner Delta Fish Protective Facility, California

open access: yesCalifornia Fish and Wildlife Journal, 2023
The John E. Skinner Delta Fish Protective Facility (Skinner Fish Facility) diverts entrained fish from the State Water Project’s pumping facilities in the southern Sacramento-San Joaquin Delta (the Delta) and transports them via tanker trucks away from ...
