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.

Download or read book The Zoogeography of North American Freshwater Fishes written by Charles H. Hocutt and published by Wiley-Interscience. This book was released on 1986-04-30 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Zoogeography of North American Freshwater Fishes is a timely, authoritative monograph which serves a twofold purpose. First, it discusses the distribution of North American freshwater fish throughout the continent. It then attempts to explain these observed distribution patterns and develops a theory for the dispersal and evolution of these fishes through historical drainage alterations, plate tectonics, and Pleistoscene glaciation. The Zoogeography of North American Freshwater Fishes is a comprehensive treatment of the freshwater biogeography of North America, with implications for other disciplines. It stresses the intimate relationship between geological changes in the landscape on fish dispersal and evolution. For biologists, geologists, and geographers actively involved in biogeography, this book serves as a valuable-and practical-reference.
