Saugeye (Sander v. male x S. canadensis female) have been stocked in Ohio with varying success since the 1970’s. Because these fish are a valuable game species, it is important to understand factors regulating their success. Other studies in our lab (see Saugeye Stocking project) have been conducted on the interaction between prey resources and saugeye stocking success and survival. This study focuses on habitat type and availability and the influence it has on saugeye distribution, saugeye abundance, and prey availability. The study has two objectives:

1. To quantify seasonal habitat use by saugeye in Hoover Reservoir as it relates to substrate, bathymetry, water temperature, and prey distribution. We will use hydroacoustics, temperature loggers, and geographic information system (GIS) to develop substrate, depth, temperature, and prey distribution maps of Hoover Reservoir. Using radio telemetry, we will characterize saugeye movement and habitat use in relation to these factors.

2. To develop a standardized procedure for mapping reservoir substrate. Based on results of objective one, we will develop a standardized procedure that can be used as a template for the development of similar habitat maps in reservoirs throughout Ohio.
