This book was released on 2014 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The popularity of catfish Ictaluridae nationally as a sport fish is well documented and angling for catfish on the Missouri River in Nebraska (NMR) is especially popular. Catfish monitoring program by the Nebraska Game and Parks Commission (NGPC) began in 1974 and several short-term evaluations of Channel Catfish population dynamics have been performed. However, no long term analyses of population characteristics have been conducted since the early 1990s. The focus of this research was to summarize the status of Channel Catfish populations in the NMR and give recommendations for future management. I summarized population characteristics, modeled length limit regulations, and assessed the feasibility of a survey design aimed at gathering effort and catch data from setline anglers. Population characteristics varied among the four reaches studied. Channel Catfish in the upper unchannelized reach had relatively low mortality, moderate population densities and a long life span. The lower unchannelized reach had a population of small, slow growing Channel Catfish with high mortality rates. Population characteristics in the upper channelized reach were similar to those of the lower unchannelized reach except relative abundance was greater. The lower channelized reach had the highest mortality and the fastest growing, shortest lived fish in the study. Modeling revealed all reaches except the lower unchannelized reach could benefit from a 380-mm minimum length limit. In all cases, mean total length, mean weight, and yield would increase with a minimum length limit. A maximum length limit would likely not be effective for growing trophy sized fish in the upper unchannelized reach. Setlining is an unknown aspect of the Missouri River catfish fishery, and methods described in this study appear to be a feasible alternative to traditional creel surveys for estimating setline effort and catch.

Book Population Dynamics and Movement of Channel Catfish in the Red River of the North

Download or read book Population Dynamics and Movement of Channel Catfish in the Red River of the North written by Stephen F. Siddons and published by . This book was released on 2015 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Channel Catfish are widely distributed across North America and highly valued as a sport fish and for food. While most Channel Catfish fisheries are managed under liberal harvest regulations, the Red River of the North (Red River) in Manitoba, Canada is managed with restrictive harvest regulations to promote a trophy fishery. Two barriers (dams) are present on the main stem of the Red River and may fragment the population to some degree. My objectives were to: 1) analyze population dynamics of the trophy Channel Catfish population on the lower Red River, 2) compare population characteristics of Channel Catfish in selected reaches throughout the Red River in Manitoba, and 3) determine movement characteristics of Channel Catfish and the permeability of a dam on the lower Red River. We compared our results to the most recent studies on Channel Catfish in the Red River, and also to range-wide age, growth, and mortality statistics. Channel Catfish in the lower Red River commonly reached ages > 20, grew slowly, and had a low mortality rate. Trophy Channel Catfish were most abundant below the dam on the lower river. The size structure within the most upstream reaches we studied were predominantly comprised of small- and intermediate-sized Channel Catfish. We determined the dam is passable by large Channel Catfish (>600 mm), but may be an impediment to small Channel Catfish. My mark-recapture data indicated Channel Catfish can move long distances, where upstream movements > 500 kilometers were common for large Channel Catfish. This research provides insight into the age, growth, and mortality of a trophy fishery for Channel Catfish. We believe restrictive harvest regulations are adequately maintaining the desired age structure and size structure of Channel Catfish in the lower Red River and by consequence, sustaining one of the premier fisheries in North America.

Book Endangered and Threatened Species of the Platte River

Download or read book Endangered and Threatened Species of the Platte River written by National Research Council and published by National Academies Press. This book was released on 2005-02-24 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.

Available in PDF, EPUB and Kindle. Book excerpt: The Missouri River Ecosystem: Exploring the Prospects for Recovery resulted from a study conducted at the request of the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers. The nation's longest river, the Missouri River and its floodplain ecosystem experienced substantial environmental and hydrologic changes during the twentieth century. The context of Missouri River dam and reservoir system management is marked by sharp differences between stakeholders regarding the river's proper management regime. The management agencies have been challenged to determine the appropriate balance between these competing interests. This Water Science and Technology Board report reviews the ecological state of the river and floodplain ecosystem, scientific research of the ecosystem, and the prospects for implementing an adaptive management approach, all with a view toward helping move beyond ongoing scientific and other differences. The report notes that continued ecological degradation of the ecosystem is certain unless some portion of pre-settlement river flows and processes were restored. The report also includes recommendations to enhance scientific knowledge through carefully planned and monitored river management actions and the enactment of a Missouri River Protection and Recovery Act.

Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
