This book was released on 1963 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differences in hyoid teeth and spotting counts among samples from four related populations of Yellowstone cutthroat trout, Salmo clarki lewisi Girard, reached species and subspecies levels as defined by some workers. Body coloration varied significantly among fish in six spawning runs of Yellowstone Lake, Wyo. The use of coloration, spotting, and hyoid teeth counts in cutthroat trout for taxonomic purposes needs reevalution.

This book was released on 1961 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a study of the Yellowstone Lake cutthroat trout, Salmo clarki lewisi, by the U.S. Fish and Wildlife Service, effects of environment on mortality of eggs, immature fish, spawners, and postspawners were measured for various components of the population in Yellowstone Lake (Wyoming). Five methods for estimating mortality of adults on spawning runs are described, with counting and tagging as the principal procedures. Of the total number of eggs deposited in the gravel, 60 to 75 percent died before hatching, and 99.6 percent had died by the time the fingerlings enetered Yellowstone Lake. In Arnica Creek runs, 48.6 percent died in the stream, 40.2 died later in the lake of natural causes, 7.6 were taken by fishermen, and 3.6 percent were alive 2 years later. The white pelican is a serious predator on cutthroat trout in Yellowstone Lake. From 1949 to 1953 fishermen caught 11.6 percent of the catchable trout available to them. Migrations of adult fish in Yellowstone Lake were traced through tagging.

Download or read book The Development of Fishery Compartments and Population Rate Coefficients for Use in Reservoir Ecosystem Modeling written by George R. Leidy and published by . This book was released on 1977 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of analyses designed to develop model fishery compartments and associated fish population rate coefficients on a regional basis for use in reservoir ecosystem modeling are presented. Emphasis is directed toward development of regional rate coefficients for the United States corresponding to major geographical drainage areas. Fishery data will be incorporated in the reservoir ecosystem model currently being developed by personnel of the Environmental Effects Laboratory, U.S. Army Engineer Waterways Experiment Station. Known physical, chemical, and fishery conditions in 187 Corps of Engineers (CE) impoundments larger than 500 acres are described. Multivariable equations are presented that allow estimation of standing crop and sport fish harvest in CE reservoirs. Data were also reviewed and summarized on the ecological growth and assimilation efficiencies of fish, food consumption rates, respiration rates, temperature tolerances, half-saturation constants for growth, and chemical composition.

This book was released on 1958 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first large-scale attempt at controlling the red tide was made in the autumn of 1957. About 16 square miles stretching along 32 miles of shoreline from Anclote Key to Pass-a-grille Beach, off St. Petersburg, Florida, were dusted with copper sulfate (CuSO4·5H2O) at about 20 pounds to the acre by crop-dusting planes. The copper very quickly reduced G̲y̲m̲ṉo̲ḏi̲ṉi̲u̲m̲ ḇṟe̲v̲e̲, the red tide organisms, from several million to practically none per liter relieving the area of the respiratory irritation caused by the airborne toxin of G̲. ḇṟe̲v̲e̲. In 2 out of 5 areas the organisms rose again to concentrations lethal to fish in 10 to 14 days after dusting. This method is not recommended for general control, but will give temporary relief in local situations from the airborne toxin
