Dec 31, 2014 · The Delta Smelt listing was related to a step decline in the early 1980s; however, population abundance decreased even further with the onset of the “pelagic organism decline” (POD) around 2002. A substantial, albeit short-lived, increase in abundance of all life stages in 2011 showed that the Delta Smelt population can still rebound when ...
The Delta Smelt is endemic to the upper San Francisco Estuary. Much of its historic habitat is no longer available and remaining habitat is increasingly unable to sustain the population. As a listed species living in the central node of California’s water supply system, Delta Smelt has been the focus of a large research effort to understand ...
Oct 3, 2022 · Delta Smelt, Hypomesus transpacificus McAllister, 1963, is a small, silvery fish endemic to the upper San Francisco Estuary (SFE), where water from the Pacific Ocean mixes with freshwater from the ...
May 29, 2022 · Only the Delta Smelt had legal clout, so other species could be largely ignored by managers, at least until Longfin Smelt, Spring-run Chinook, and Green Sturgeon also became listed under the ESA. Sacramento Splittail were listed for a short period but became delisted as more and better information on their biology developed (Moyle et al. 2004).
Early studies of Delta Smelt distribution within the SFE suggested that Delta Smelt summer and fall habitat is closely associated with freshwater flow, which affects the location and extent of the low-salinity zone of the estuary (Moyle et al. 1992).
Oct 22, 2019 · The delta smelt, an unassuming, finger-size fish with little utility beyond its role as an environmental sentry, has been at the center of California’s water wars for nearly three decades.
