This dataset represents a species habitat distribution map for Cinnamon Teal (Anas cyanoptera) within the conterminous United States (CONUS) based on 2001 ground conditions. This habitat map was created by applying a deductive habitat model to remotely-sensed data layers within the species' known range. See Gap Analysis Project Species Habitat Maps for more information regarding model process and user constraints. For species specific model information, see the attached Species Habitat Model Report.
The Bering Cisco (Coregonus laurettae) is endemic to Alaska and is present primarily along the State’s west and north coasts. It is known to spawn in only three river systems – the Yukon, Kuskokwim, and Susitna Rivers. Genetic research indicates that each of these populations is distinct. The Bering Cisco has been observed to migrate more than 1,200 miles into freshwater streams to spawn. Unlike salmon, some of these fish survive spawning runs. Since this species is slow-growing but short-lived, it is highly vulnerable to alterations in stream flow or water quality and large-scale environmental disasters.
Partnerships - Atlantic Coastal Fish Habitat Partnership, Eastern Brook Trout Joint Venture, Reservoir Fisheries Habitat Partnership, and Southeast Aquatic Resources Partnership Removed four barriers that opened access to six mile of streams and restored 21 miles of streams to improve habitat for Eastern Brook Trout and other fish species. A shoreline restoration demonstration area was constructed near the U.S. Army Corps of Engineers Visitors Center in North Carolina. Native vegetation was used to stabilize 175’ of shoreline to be used as a showcase for other lakeshore property owners. Planted 0.2 acres of tidal marsh and installed 0.1 acres of oyster reefs in Stump Sound, North Carolina. Also planted 0.15 acres...
This ScienceBase item provides the queries and code that identifies components and organization of the detailed methodology for the National Fish Habitat Partnership's regional estuary assessment for the Northern Gulf of Mexico.
Available data for the American Eel (Anguilla rostrata) indicate that, overall, there have been declines in recruitment, population, and escapement during three generations (36 years). A recent report indicated that barriers to migration (dams and weirs), passage through turbines at hydropower dams, habitat degradation or loss, and overharvest were likely the greatest threats by humans across the species’ range. Although eels are able to ascend many smaller barriers, recent studies have documented a tenfold reduction in eel density above each potentially passable barrier. For example, the number of juvenile eels migrating to Lake Ontario passing over hydropower dams fell from 935,000 in 1985 to approximately 8,000...
The habitats of the Southeast Atlantic states range from the mountains and uplands in the Blue Ridge and Piedmont areas in the western portion of this region to the Southeastern and Coastal Plains. Fish habitats in the higher elevation regions are typically fast-moving, clear, coldwater streams originating from seeps and springs, while warmwater rivers of the plains carry more organic material and sediment. This diversity of habitats along a very long period of stable geologic activity produces one of the most diverse assemblages of aquatic species in the nation. The Altamaha, Chattahoochee, Flint, Savannah, Catawba, Pee Dee, Broad, and Neuse are major rivers of the region. There are a large number of dams on waterways...
Partnership - Hawaii Fish Habitat Partnership Anchialine pools represent an inland waterbody type that is widespread but threatened throughout the Hawaiian Islands and is a key habitat type of concern to the Hawaii Fish Habitat Partnership. Anchialine pools, also known as fishponds in Hawaii, are near the coast and are land-locked bodies of water that have connections both to the sea, typically by high tides, as well as to local freshwater. These systems have been used for thousands of years for fish production by Native Hawaiians. The majority of remaining fishpond pools are located on the Kona coast and southern coastlines of the Big Island, the southeast coast of Maui, and on several small and widely separated...

This item provides the ScienceBase query that identifies components of the fish habitat assessments within the Central Midwest States. It also contains a link to a configuration file that pulls these pieces of information into a logical order. This information can be accessed through the ScienceBase API to display a summary of fish habitat assessment information for the Central Mississippi River States.
State-wide data on fish populations were limited in Alaska for use in this assessment, as was a detailed spatial (mapping) framework that fully characterizes watersheds throughout the state at the time this assessment was conducted. Because of these factors, we modified our assessment methods to account for these limitations. Twenty-one landscape disturbance variables were assembled from medium-sized watersheds throughout the state (i.e., 12-digit hydrologic unit code watersheds). Variables were then assigned to one of six categories based on their disturbances to stream habitats. Categories include: urban land use, agricultural land use, point source pollution and water quality, barriers to fish movement, human...

The Waccamaw Silverside (Menidia extensa) has a very limited distribution confined to Lake Waccamaw in North Carolina, a lake with neutral pH levels from underlying limestone formations in an area of acidic natural waters. This species is found in large schools and often over dark-colored substrates. Its limited habitat is threatened by nutrient loading caused by the runoff of organic matter and agricultural chemicals.
The Ironcolor Shiner (Notropis chalybaeus) is found in deep pool areas of creeks and small rivers and is often associated with aquatic vegetation. This species needs clear sandy areas for spawning. Populations of Ironcolor Shiner are in decline due to increased turbidity, siltation, and pollution.
A total of 73 fish representing 5 species from the Muddy River and cooling pond of the Moapa Power Plant in Nevada was examined for Bothriocephalus acheilognathi (Yamaguti, 1934) (Asian fish tapeworm) and other parasites. Three of 14 Cyprinella lutrensis(Baird and Girard, 1853) from the Muddy River and 10 of 11 Gila robusta (Baird and Girard, 1853) from the cooling pond of the Moapa Power Plant in Nevada were infected with Bothriocephalus acheilognathi. From 79 fish examined from 4 bait fish shops in the Las Vegas, Nevada, area 3 of 38 Notemigonis crysoleucas (Mitchill, 1814) were infected with B. acheilognathi but none of the 41 Pimephales promelas (Rafinesque, 1820) was infected. The bait fish were originally...
In the mostly arid Southwestern United States, water availability (hydrology – a key fish habitat process), wildfires, and grazing intensity are important disturbances that are known to have major, negative effects on fish habitats. While this assessment indicated that many of the streams in this region are in good condition, a number of key habitat variables (i.e. water availability, wildlife frequency and intensity, and grazing intensity) could not be directly included in this assessment because national datasets of these disturbances and their measured variable are unavailable. Their absence from this assessment, along with absences of other disturbances, has likely produced an overestimation of habitat condition...
