OBJECTIVE 3 <br />APPROACH <br />Locations of sturgeon, sturgeon chub and associated species and the habitats they use will <br />be related to ambient conditions in the Platte River. A relational database and a Geographic <br />Information System (GIS) are being developed for the analysis of the spatial and temporal habitat <br />use of pallid sturgeon and sturgeon chub in the lower Platte River. The relational database <br />provides a single, coordinated location for the storage and management of field data being <br />collected in the different sections of this project. The benefits of a relational database include the <br />ability to standardize the data collection process among field studies to allow for appropriate <br />integration of the data. Also, the database allows available data from other sources (i.e. flow data <br />from United States Geological Survey gauge sites, or water quality data from Nebraska <br />Department of Environmental Quality) to be incorporated with the data collected on the habitat <br />use of the fishes. In addition, by including accurate time and location information for all data <br />within the database, there is a built -in compatibility with GIS platforms. GIS provides the ability <br />to visualize and analyze the spatial and temporal relationships between the many aspects of the <br />overall project. By combining the findings from each field study, a generalized picture of the fish <br />habitat use and movement may emerge. In addition to improving the description of suitable <br />habitat for the pallid sturgeon and sturgeon chub, the GIS imparts a mechanism to begin to <br />synthesize the data on general habitat availability within the lower reaches of the Platte River and <br />allows results from the different collecting techniques to be compared. <br />14 ��� <br />
