Download or read book Fish Passage Through Culverts written by Calvin O. Baker and published by . This book was released on 1990 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of fish migration through culverts is dependent on the swimming ability of the fish and the hydraulic conditions of the culvert. Properly designed and constructed culverts can minimize the impact on fish passage. Because culverts are typically more economical than bridges, it is appropriate to evaluate when to use culverts and to predict the effects of such culvert installations. During the consideration of alternatives for structures for fish passage, culverts should not be automatically eliminated. This publication has tried to examine the aspects of culvert design and operation relative to the existing information that has been published in previous studies. Ideally, a culvert installation should not change the conditions that existed prior to that installation. This means that the cross-sectional area should not be restricted by the culvert, the slope should not change, and the roughness coefficients should remain the same. Any change in these conditions will result in a velocity change which could alter the sediment transportation capacity of the stream. A truly successful culvert design would include matching the velocities of the fish's swimming zone in the culvert to the swimming capacity of the design fish. Unfortunately, not enough research has been completed to make this an acceptable criterion of culvert design. This approach is preferred because it is easier to reduce the velocities in the swimming zone by increasing the boundary roughness than it is to reduce the mean velocity of the entire culvert. This publication contains some relatively simple guidelines which can reduce the installation problems of culverts in streams containing migrating fish when combined with the expertise of an experience fish biologist, engineer, and hydrologist.

This book was released on 1982 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large river systems are valuable national resources that provide numerous benefits to travel, shipping, recreation, and fish and wildlife. However, efforts to expand one of the uses frequently come in direct conflict with one or more of the othersThis guide attempts to bring together all scientific data that are available on techniques that have been or can be used to offset or reduce the impacts of development and maintenance of Upper Mississippi River System or other large river systems. Decision makers are thus provided an objective descriptin of options now at their disposal when they attempt to weigh the merits of defects associated with a particular action.

Jessop and published by Department of the Environment, Fisheries and Marine Service, Fisheries Operation Directorate (Central Region), Resource Management Branch, Resource Impact Division. This book was released on 1975 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: In April 1974, the Department of the Environment, Fisheries and Marine Service began the final year of a four year investigation into possible effects of pipeline construction on fish resources of the Mackenzie River valley. The present program includes new and revised findings from the 1974 program. During 1974, emphasis was placed on refining and adding to life history data, particularly migration routes and timing, movements of fry and juveniles and location of overwintering areas. The fish tagging program was intensified on several systems in each study area. A fish fence was constructed in the Trail River to monitor fish movements and to obtain spawning population estimates. Fry traps were used to determine movements of fry and juveniles. A winter survey was conducted to locate significant overwintering areas. Pertinent information on species distribution and migration routes obtained by Fisheries and Marine Service crews based on Richards Island and the Great Bear River also has been incorporated.

Download or read book The Ecology of River Systems written by Bryan R. Davies and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the ecology of running waters has come a long way during the past few years. From being a largely descriptive subject, with a few under tones concerned with such things as fisheries, pollution or control of blackflies, it has evolved into a discipline with hypotheses, such as the River Continuum Concept (Vannote et a/. 1980), and even a book suggesting that it offers opportunity for the testing of ecological theory (Barnes & Minshall 1983). However, perusal of the literature reveals that, although some of the very early studies were concerned with large rivers (references in Hynes 1970), the great mass of the work that has been done on running water has been on streams and small rivers, and information on larger rivers is either on such limited topics as fisheries or plankton, scattered among the journals, or not available to the general limnologist. The only exceptions are a few books in this series of publications, such as those on the Nile (Rz6ska 1976), the Volga (Morduckai Boltovskoi 1979) and the Amazon {Sioli 1984), and the recent compendium by Whitton (1984) on European rivers, among which there are a few that rate as large.
