This book was released on 2021-11-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walleye, one of the most sought-after species of freshwater sport fishes in North America, has demonstrated appreciable declines in their numbers from their original populations since the beginning of the 20th century. Similarly, Yellow Perch, once the most commonly caught sport fish and an important commercial species in North America, have also shown declines. Compiling up-to-date information on the biology and management of Walleye, Sauger, and Yellow Perch, including research on systematics, genetics, physiology, ecology, movement, population dynamics, culture, recent case histories, and management practices, will be of interest to managers, researchers, and students who deal with these important species, particularly in light of habitat alterations, population shifts, and other biotic and abiotic factors related to a changing climate.

Download or read book Spatially explicit Habitat Characterization Suitability Analysis Verification and Modelling of the Yellow Perch Perca Flavescens Mitchell 1814 Population in Long Point Bay Lake Erie microform written by Susan Elisabeth Doka and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2004 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different approaches were used to characterize, assess, test and model the fish-habitat interactions of yellow perch in Long Point Bay. Chapter 1 describes the methodologies for explicitly characterizing spatial and temporal habitat through mapping and modelling. Chapter 2 connects habitat and ontogenetic niche shifts in perch life history, with the aim of determining suitable habitat availability for the Long Point Bay perch population. Habitat suitability indices and models were used to map and identify the areas of suitable habitat, including thermal habitat. Chapter 3 compares a known distribution of yellow perch larvae with HSI predictions of habitat suitability as a validation exercise. Abundance and size distributions from the survey were compared to thermal and HSI predictions of suitable habitat to test for correspondence. The relationship between food availability and habitat characteristics, especially vegetation, were also tested. A model was developed in Chapter 4 that concentrated on the first year of life and the effect of consecutive constraints on early life stages with different habitat requirements. The purpose of the model was to compare the potential growth and survival of consecutive life stages in a spatially explicit manner when different habitat-based rules are imposed. The results highlight the importance of life history theory and knowledge of mechanisms used in habitat selection for determining limits to fish production.
Download or read book Movement Home Range and Ecological Divergence in the Commercially Fished Nile Perch in Lake Nabugabo Uganda written by Elizabeth Nyboer and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The large piscivorous Nile perch (Lates niloticus) was introduced to the Lake Victoria basin in the 1950s and 1960s and eventually became one of the most valuable commercial species of East Africa's inland fisheries. Intense fishing-induced mortality may be contributing to dramatic ecological change in this species (reductions in body size and biomass; shifts in distribution and diet), and reinforcing patterns of ecological divergence in some lakes in the region. In this thesis I use an evolutionary ecology approach to explore habitat associated ecological divergence in the Nile perch in Lake Nabugabo, Uganda. I describe home range, movement, and habitat selection of Nile perch, and quantify divergence in phenotypic traits between major habitat types and across Nile perch ontogeny. Using radio telemetry I tracked 14 Nile perch for 5 months and used ArcGIS 9.3 to quantify movement patterns throughout Lake Nabugabo. I used movement data in combination with detailed ecological information to quantify habitat selection in the heavily fished inshore zones of the lake. Geometric morphometric and colour analyses were used to quantify divergence in body shape and skin colour across different size classes of Nile perch from ecologically distinct wetland and forest edge habitats. Nile perch exhibited low levels of daily movement and relatively small home ranges; and they preferred regions of the lake characterized by low temperature and high dissolved oxygen. Geometric morphometric and colour analyses revealed habitat-associated phenotypic divergence in both skin colour and body shape, although not all trends were consistent across size classes. The source of phenotypic divergence (genetic vs. plastic) remains unknown; however the level of site tenacity exhibited by Nile perch suggests that ecological isolation between forest edge and wetland fish may be higher than expected. These results have important implications for development of territorial jurisdiction by Beach Management Units, the decentralized structure of fisheries management in the region. Knowing that Nile perch, one of the most important commercial catches in the Lake Victoria basin, have definable home ranges provides a biologically relevant rationale for the insertion of territorial boundaries for BMUs. Clearly defined resource-use boundaries may provide additional incentives for members to follow fishery rules and may prove to be instrumental in improving BMU efficacy." --

Book excerpt: The percid fishes (or perch family) comprise many species including the perch, pikeperch, yellow perch, walleye and the darters. These species are of great ecological and economic importance, being important components of the freshwater ecosystem and recreational and commercial fisheries. Percid Fishes covers aspects such as systematics, morphology, biology, ecology, diseases and parasites and the economic importance of percid fisheries. Special emphasis is placed within the book on the complex relationship between this family of fishes and their environment and how they respond to perturbations, especially those induced by humans. The author, John Craig who has a great deal of experience working on these fishes in many of the countries in which they occur, has drawn together an extremely important book which provides a unique, comprehensive and indispensable review of this most significant group of fish.
Download or read book Kansas Fishes written by Kansas Fishes Committee and published by University Press of Kansas. This book was released on 2014-07-15 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide and a first-rate reference for the angler, scientist, and amateur naturalist alike, this comprehensive volume profiles each of the 144 fish species inhabiting the waterways of Kansas--as well as 27 others that might make their way to the state from nearby river basins. With 121 maps and 184 full-color drawings by Joseph Tomelleri, arguably the best illustrator of North American fishes, Kansas Fishes is an incomparable resource. For each species, the authors, an all-star cast of regional biologists, provide information about fundamental natural history, anatomy, and physiology, along with in-state distributions, habitats, characteristics, and pertinent issues of conservation and ecology. With these experts authoring detailed accounts of the species they know best, this is a uniquely authoritative account of the region's fishes. As such, it will prove useful to students and professionals while providing the passionate amateur and the simply curious an entry into the fascinating world of the fishes of Kansas and nearby states. The Kansas Fishes Committee members represent each of the six state universities (Emporia State, Fort Hays State, Kansas State, Pittsburg State, and Wichita State Universities, and the University of Kansas), as well as the Kansas Biological Survey, the Kansas Department of Health and Environment, and the Kansas Department of Wildlife, Parks and Tourism--the people responsible for studying, protecting, and educating people about the fishes and waters of Kansas. In addition to the committee, nearly 50 biologists from the United States and Canada volunteered to contribute species accounts to the book based on their expertise with those species in Kansas and nearby states. These individuals work for a variety of universities, federal and state agencies, and private companies, making this book a broad collaboration of experts on the fish species of Kansas.

Available in PDF, EPUB and Kindle. Book excerpt: Murray-Darling Basin, Australia: Its Future Management is a much-needed text for water resources managers, water, catchment, estuarine and coastal scientists, and aquatic ecologists. The book first provides a summary of the Murray-Darling River system: its hydrology, water-related ecological assets, land uses (particularly irrigation), and its rural and regional communities; and management within the Basin, including catchments and natural resources, water resources, irrigation, environment, and monitoring and evaluation. Additionally, the recent major water reforms in the Basin are discussed, with a focus particularly on the development and implementation of the Basin Plan. Murray-Darling Basin, Australia: Its Future Management then provides an analysis of the next set of policy and institutional reforms (environmental, social, cultural and economic) needed to ensure the Basin is managed as an integrated system (including its water resources, catchment and estuary) capable of adapting to future changes. Six major challenges facing the Basin are identified and discussed, particularly within the context of predicted changes to the climate leading to an increased frequency of drought and a hotter and dryer future. Finally, a 'road map' or 'blueprint' to achieve more integrated management of the Basin is provided, together with some 'key lessons' of relevance to others involved in the management of multijurisdictional river Basins. - Provides a consolidated account of the Murray-Darling Basin system; an area of global relevance to those interested in rebalancing river systems where the water resources have been over allocated - Offers a detailed analysis of the current system and its management, with a focus on water and ecosystem management - Discusses a number of key challenges, particularly those related to climate change, facing future reforms to the Murray-Darling Basin Plan - Provides a blueprint for changes needed to ensure the Basin is managed as an integrated whole (from catchment to coast)
