This book was released on 2009 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Understanding habitat selection in fish can reveal areas critical for a population's continuation in the ecosystem. In systems experiencing habitat alterations or reductions in population sizes, identifying habitat use takes on increased importance. To facilitate our understanding of potential factors limiting the success of walleye (Sander vitreus) in Sandusky Bay, Lake Erie, we combined walleye locations determined from radio telemetry with habitat predictor variables to model habitat use and reveal sex-specific patterns of habitat use throughout the spawning season (Chapter 2). Models revealed that the presence of preferred walleye spawning substrate, gravel and cobble, was an important predictor of walleye locations during the entire spawning season, and depth and distance from shore were important particularly prior to the spawn. In examining sex-specific patterns of habitat use, we discovered that males were more likely to occur over gravel and cobble substrates than females. We hypothesize that males establish position in these areas in anticipation of spawning females. Only a small proportion of walleye tagged in Sandusky Bay migrated to upstream spawning grounds (2 of 197; 1%). To confirm whether walleye spawning occurs in Sandusky Bay and to analyze how spawning substrate might affect egg deposition rates and viability, we compared eggs collected using spawning mats from gravel/cobble and sand/silt substrates (Chapter 3). Egg deposition and egg viability were not significantly different between substrates, and the majority of walleye eggs were collected from one site that contained gravel and cobble. The combined results of this investigation reveal that the Sandusky Bay is a spawning ground for walleye and that preferred spawning substrate is an important factor predicting the location of walleye during the spawn. Because the amount of spawning habitat in this system has declined by an estimated 92% during the past century, we recommend that conservation and restoration steps be taken to preserve this walleye spawning population.

Available in PDF, EPUB and Kindle. Book excerpt: Radio telemetry, larval fish sampling, egg baskets, and scapnetting were utilized to determine walleye Sander vitreus spawning sites in Lake Bemidji, Minnesota, during the spring spawning periods of 2002 through 2004. Some walleye populations travel from their lake environments into rivers or streams to spawn, but Lake Bemidji walleyes appear to be lake spawners. No tracked walleyes were found in river habitats during the 2002 spawning season. Based on radio telemetry, six putative spawning areas were located: Rocky Point at Lake Bemidji State Park, northwestern shore of the north basin, weed beds (bulrush Scirpus spp.) on each side of the Mississippi River outlet on the east side of the lake, Diamond Point, and the ridge between Diamond Point and the outlet of the Mississippi River. The greatest concentration of spawning walleyes occurred along the ridge between Diamond Point and the outlet of the Mississippi River in relatively shallow water over more coarse substrate than is typically found in the lake. No walleye eggs were found in egg baskets placed in putative spawning areas during 2003, but one was found by scapnetting on the ridge off of Diamond Point during spring 2004. These methods were conducted in shallow waters less than 1.5 m deep. Spawning shoals may be relatively small and isolated in waters deeper than 1.5 m. further studies utilizing a combination of SCUBA or an underwater video camera and scapnetting should be conducted to pinpoint spawning sites in deeper waters. Based on the presence of adequate natural recruitment, the amount of walleye spawning habitat does not appear to be limiting. Thus, habitat enhancement is not recommended at this time.

This book was released on 2005 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1995, Kentucky Department of Fish and Wildlife Resources (KDFWR) biologists discovered the presence of what was once thought to have been a lost native river run walleye (Sander vitreus). The native population was thought to have been extirpated due to dams and stocking of Lake Erie walleye (since 1973) into Lake Cumberland, but KDFWR and collaborating geneticists confirmed the strain persisted in the Rockcastle River. The purpose of this study was to determine how the natives remained reproductively isolated from the introduced Lake Erie strain. Radio telemetry was used to determine home range, seasonal movement patterns, and spawning locations, as well as habitat characteristics for these natives in the Rockcastle River. Efforts were made to implant transmitters in 40 native and 20 Lake Erie walleye, but genetic analysis of fin clips revealed that all walleye captured were native. Thus, data collected from fall 2003 to the end of spring 2005 were for 60 native individuals. Movements indicated upstream spawning from March through early April; and widely varying downstream post-spawning movements. Seasonally, high water discharges in February and March were cues for upstream movements to pool areas below spawning sites at shallow gravel riffles. Twenty-four hour monitoring revealed fish to be most active during the night with peak activity at sunrise and sunset. Movement patterns resembled that of other studies, with respect to spawning migrations, limited summer activity, and increased activity in the fall, late winter, and spring seasons. In total, approximately 370 walleye were captured during this study, and all but one small individual (collected in the lower Rockcastle River) were confirmed as natives through genetic analysis. Based on these collecting efforts, it is likely there is negligible interaction between native and Lake Erie walleye. In addition, the native walleye tend to migrate farther upstream to spawn, thus, further reducing the chances for hybridization between the two strains. In conclusion, this study will aid the KDFWR in their preservation efforts of the native walleye in the Rockcastle River by suggesting better places to stock and identifying key river sections as walleye spawning sites that should remain undisturbed.
