Smelts are a family of small fish, the Osmeridae, found in the North Atlantic and North Pacific oceans, as well as rivers, streams and lakes in Europe, North America and Northeast Asia. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae, Bathylagidae, and Retropinnidae.
The Sacramento perch is from the family, Centrarchidae, characterized by dorsal fins with spiny elements and known for its nesting behavior. There are about 31 species in this family, which include sunfishes, crappies, and basses. The Sacramento perch is considered in the sunfish group. It is the only species of Centrarchidae whose native habitat resides west of the Rocky Mountains, while all the other species are native to the east.
Pink salmon or humpback salmon is a species of euryhaline ray-finned fish in the family Salmonidae. It is the type species of the genus Oncorhynchus, and is the smallest and most abundant of the seven officially recognized species of salmon. The species' scientific name is based on the Russian common name for this species gorbúša (горбуша), which literally means humpie.
Hachirōgata or Hachirō Lagoon is a lake in Akita Prefecture in northern Japan. Its formal name is Lake Hachirō, but it is also called Hachirōgata Regulating Pond. At 4 meters below sea level, Hachirōgata is the lowest natural point in Japan.
The delta smelt is an endangered slender-bodied smelt, about 5 to 7 cm long, in the family Osmeridae. Endemic 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. It functions as an indicator species for the overall health of the Delta's ecosystem.Delta Smelt are usually found at temperatures of less than 25°C and prefer temperatures of around 20°C. They are euryhaline but occur mostly at salinities of 0–7 practical salinity units.
The Sacramento blackfish is a species of freshwater fish in central California. A cyprinid, the blackfish is the sole member of its genus.
Hypomesus is a genus of smelts (Osmeridae), consisting of five species found in the northern hemisphere.
The longfin smelt is a smelt that is found in several estuaries and lakes along the northern Pacific coast of North America.
San Leandro Creek is a 21.7-mile-long (34.9 km) year-round natural stream in the hills above Oakland in Alameda County and Contra Costa County of the East Bay in northern California.
The green sturgeon is a species of sturgeon native to the northern Pacific Ocean, from China and Russia to Canada and the United States.
Hypomesus japonicus, the Japanese smelt, is a coastal fish species of the northwestern Pacific Ocean, ranging from the Korean Peninsula and northern Japan to the Kuril Islands and Peter the Great Bay.
The San Francisco Estuary together with the Sacramento–San Joaquin River Delta represents a highly altered ecosystem. The region has been heavily re-engineered to accommodate the needs of water delivery, shipping, agriculture, and most recently, suburban development. These needs have wrought direct changes in the movement of water and the nature of the landscape, and indirect changes from the introduction of non-native species. New species have altered the architecture of the food web as surely as levees have altered the landscape of islands and channels that form the complex system known as the Delta.
The Night smelt is a true smelt of the northern family Osmeridae and part of the larger order Osmeriformes. The family of the true smelt consists of 12 species; 7 of which are native to California’s estuary and coastal waters. The night smelt is one of the three exact species in the Spirinchus genus, along with the Longfin Smelt (Spirinchus thaleichthys) and the shishamo (Spirinchus lanceolatus), native to northern Japan.
Lake Abashiri is a meromictic lake in Abashiri, Hokkaidō, Japan. It is located in Abashiri Quasi-National Park. The Abashiri and Memanbetsu Rivers flow into the lake. Water exits the lake through the Abashiri River again and flows 7 kilometres (4.3 mi) to the Sea of Okhotsk.

Marsh Creek is a stream in east Contra Costa County, California in Northern California which rises on the eastern side of Mount Diablo and flows 30 miles (48 km) to the Sacramento–San Joaquin River Delta at Oakley, California, near Big Break Regional Shoreline. The creek flows through Marsh Creek State Park (California), where water is impounded to form Marsh Creek Reservoir, then through the city of Brentwood, California.
Searsville Dam is a masonry dam in San Mateo County, California, that was completed in 1892, one year after the founding of Stanford University, and impounds Corte Madera Creek to form a reservoir known as Searsville Reservoir or Searsville Lake. Searsville Dam is located in the Jasper Ridge Biological Preserve and is owned and operated by Stanford University. Neighboring cities include Woodside and Portola Valley, California.
Peter B. Moyle is Distinguished Professor Emeritus in the Department of Wildlife, Fish and Conservation Biology and associate director of the Center for Watershed Sciences at the University of California, Davis. He has studied the ecology and conservation of fishes in freshwater and estuarine habitats in California (US) for over fifty years. He has a special interest in salmonid fishes and in the state's highly endemic freshwater and estuarine fish fauna. Moyle has authored or co-authored more than 270 peer-reviewed publications, including 10 books, and over 225 other publications, including ca. 75 blogs.
Coreoperca kawamebari, commonly known as the Japanese perch, redfin perch, Japanese river perch, eye-spot perch, fire tiger or in Anglophone parts of Japan, simply the perch, is a predatory species of ray-finned fish native to Japan and southern Korea. They are sometimes kept as pets.
