Book Synopsis Determining Spawning Occurrence and Reproductive Potential of Shenango River Lake Walleye by : Michael T. Hamilton

This book was released on 2009 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was to achieve an assessment of walleye (Sander vitreus) spawning through the collection of eggs and physico-chemical data in the Shenango River, from the Shenango River Lake extending upstream approximately 24 river kilometers. It is generally thought that successful spawning of walleye in Pennsylvania is nearly non-existent, but the research to support this is limited. The data collected during sampling included river depth, flow velocity, water temperature, dissolved oxygen, pH, and river substrate content. This data will provide a baseline for future studies of the Shenango River and similar fisheries. This information was compared with that of other studies on walleye spawning habitat to establish a Walleye Spawning Qualitative Habitat Evaluation Index (WSQHEI). Walleye spawning attempts by Shenango River Lake walleye in the Shenango River was confirmed by this study. The WSQHEI appeared unsuitable for predicting walleye spawning in the Shenango River. Physico-chemical data displayed minimal gradients, which limited the development and effectiveness of the WSQHEI. This occurred because sampling was restricted to areas conducive to walleye spawning based upon literature of known environmental variables. Although walleye spawning activity was unrelated to environmental conditions among sites, migration distance was negatively correlated with walleye spawning activity. Sampling in 2008 and 2009 indicated that spawning occurrence decreased as distance from Shenango River Lake increased. The WSQHEI could be useful for baseline assessments when little or no data are available about the walleye spawning activities in a lotic system.

Book Synopsis Spawning Habitats of Walleyes Sander Vitreus in Lake Bemidji, Minnesota by : Matthew J. Sperry
Download or read book Spawning Habitats of Walleyes Sander Vitreus in Lake Bemidji, Minnesota written by Matthew J. Sperry and published by . This book was released on 2006 with total page 84 pages. 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 2008 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Current concerns about the repercussions of global climate change have stimulated efforts to understand how changing abiotic conditions influence natural populations. Walleye (Sander vitreus) populations have shown marked annual variability that can not be predicted by the size of the spawning population. Previous research has associated this variability with environmental factors such as spring warming rate, river discharge, and storm frequency and intensity. Frequently, however, the predictability of models developed from these studies falters as new data points are added and previous relationships are weakened. Relationships between recruitment and abiotic variables may disintegrate because of the interaction between local and large-scale variables that may not be detected in short time series but become more apparent when many more years are added. By comparing multiple populations within a region, the effects of large-scale variables and local variables should be possible to distinguish, with years of covariation representing years in which climate (or other large-scale factors) is influencing recruitment. We examined the effects of climate on recruitment of walleye by comparing four populations of walleye in the Great Lakes (west basin, Lake Erie, Saginaw Bay, Lake Huron, Green Bay, Lake Michigan, and Bay of Quinte, Lake Ontario) for synchrony of recruitment. Synchrony in recruitment among populations was determined using Pearson's product moment coefficient, and both single site and multi site models were created to test a set of a priori hypotheses regarding various local and large-scale factors influencing recruitment. Synchrony of recruitment occurred between three sites: west basin, Lake Erie, Green Bay, Lake Michigan, and Bay of Quinte, Lake Ontario during 2000-2004. El Niño-Southen Oscillation and the North Atlantic Oscillation were the best predictors of recruitment during 2000-2004. These results suggest that in addition to local weather conditions, large-scale factors influence walleye recruitment in the Great Lakes, and were the dominant variables influencing recruitment during this time. Understanding whether future changes in climate will cause overall increases or decreases in recruitment may help managers choose between more conservative and more liberal management strategies.
