Delta Smelt
The delta smelt (''Hypomesus transpacificus'') is an endangered slender-bodied smelt, about long, in the family Osmeridae. Non-Indigenous to the upper Sacramento-San Joaquin Estuary of California, it mainly inhabits the freshwater-saltwater mixing zone of the estuary, except during its spawning season, when it migrates upstream to fresh water following winter "first flush" flow events (around March to May). It functions as an indicator species for the overall health of the Delta's ecosystem. Because of its one-year lifecycle and relatively low fecundity, it is very susceptible to changes in the environmental conditions of its native habitat.Moyle, PB. 2002. Inland fishes of California. University of California Press, Berkeley. Efforts to protect the endangered fish from further decline have focused on limiting or modifying the large-scale pumping activities of state and federal water projects at the southern end of the estuary, thereby limiting water available to farming.

Sacramento Splittail
The splittail (''Pogonichthys macrolepidotus''), also called Sacramento splittail, is a cyprinid fish native to the low-elevation waters of the Central Valley in California. It was first described by William O. Ayres in 1854. It is the sole living member of its genus, the Clear Lake splittail ''P. ciscoides'' having become extinct in the 1970s. The distinctive feature of the splittail is the larger upper lobe of the tail fin. It also has tiny barbels at the corners of the mouth. The dorsal fin has 9-10 rays, while the pectoral fins have 16-19 rays, the pelvic fin 8-9 rays, and the anal fin 7-9 rays. Color is silver on the sides, with a dusky olive gray on the back; during the breeding season the fins pick up a red-orange tinge, and the males become darker and develop white tubercles on the head and at the bases of the fins. They feed on bottom-dwelling invertebrates and detritus, generally in areas of low to moderate current. In Suisun Bay, opossum shrimp (mostly ''Neomysis ...

Vernal Pool Fairy Shrimp

As of the 2010 census, the city population was 9,089. The population has since grown to 10,370 as of the 2018 population estimate. History Vernal, unlike most Utah towns, was not settled by Mormon Settlers. Brigham Young sent a scouting party to the area Uintah Basin in 1861 and received word back the area was good for nothing but nomad purposes, hunting grounds for Indians, and "to hold the world together." That same year, President Abraham Lincoln set the area aside as the Uintah Indian Reservation, with Captain Pardon Dodds appointed Indian agent. Dodds later built the first cabin erected by a white man in the Uintah Basin around 1868. Settlers began to filter in after that, and built cabins in various spots on or near Ashley Creek. In 1879 many came close to perishing during the infamous "Hard Winter" of that same year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
