The Arizona Game and Fish Department (AGFD) recognizes the need for a strong data foundation to inform science-based decisions for fisheries management at a watershed level. In preparation for a shift towards comprehensive watershed-scale planning, AGFD is developing a fisheries data management system with an initial focus on compiling and formatting several hundred thousand fish survey and stocking records. Fish data will be integrated within a Geographic Information System (GIS) by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which will allow for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by...

Problem - The Ithaca Subdistrict Office of the U.S. Geological Survey (USGS) is providing technical assistance to the USGS, Biological Resources Division (BRD), at the Tunison Laboratory of Aquatic Science (TLAS) in an investigation of the availability of fresh ground water. An expansion in the water supply at the laboratory is needed for a proposed spawning facility for salmon strains that are viable for natural fisheries in the Great Lakes region. The hydrogeology of the area is a complex of moraine and outwash deposits west of Cortland, N.Y. Data from existing wells at the laboratory indicate that well screens may readily clog from precipitated minerals. A review of the hydrogeology of the area, including...

Problem - Acidic precipitation has affected forested and aquatic ecosystems in New York, particularly in the Adirondack and Catskill regions. Acidification of surface waters and deleterious effects on fish and other biota have been well documented in both these regions. Despite reduced levels of acidity in atmospheric deposition over the past 20 years across New York and the northeastern United States, the most acid-sensitive streams and lakes have not yet begun to recover, and many show continued declines in acid-neutralizing capacity, an indicator acid-base status. Many studies have documented the effects of acid precipitation in New York, but thus far, there has been no comprehensive effort to synthesize and...

Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal trends and potential recovery of fish assemblages in less acidic or less toxic streams. Though the effects of acidification on fish assemblages have been qualified in several streams of the eastern Adirondacks during 1979, the 1980s, and early 2000s, (Schofield and Driscoll 1987; Simonin et al. 2005) quantitative impacts were...

Freshwater fishes are globally among the most imperiled major biodiversity groups and they are especially endangered in the North American deserts of the vast binational Desert LCC. Sixty seven native fish species of conservation concern are in the study area, which includes all of the DLCC in both the US and Mexico. Essentially all species in our study area are understudied and management of them has been greatly impeded by the intrinsic difficulties of working internationally and by relative lack of, or inaccessibility to, basic knowledge about their distributions and conservation status. We propose to mine data from all online and known US-based institutions holding specimen-based occurrence records from our...

The potential implications of climate change to fishes in Great Plains rivers and streams could range from drastic shifts in distribution to extirpation. Many lotic systems in the Great Plains are not well suited for direct escape routes for fish to move to more suitable habitats at other latitudes due to the west-east direction of flows rather than north-south. Therefore, we might expect additional climate related stress on fish communities in the Great Plains compared to other regions of North America. Therefore, we will 1) simulate potential water temperature and flow changes within the Great Plains based on extant regional climate models, 2) assess stream connectivity to potential refugia, 3) develop a database...
