This book was released on 2016-10-04 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Spawning Escapement of Okanogan River Blueback Salmon (Oncorhynchus Nerka), 1957 The 1957 return of blueback was of special interest since the he's were the progeny of the 1953 escapement which was one of the largest in recent years. The most unusual feature of the 1953 run was that over 86 percent of the Okanogan spawners were 3-year-old fish whose sex ratio of males to females was The bulk of these 3-year-old fish escape the fishery and continue to the Okanogan where in normal years they comprise about 22 percent of the spawning population. These small fish seem to be peculiar to the Okanogan and are seldom encountered in the other two systems. Table 6 demonstrates the occurrence of 3-year-old Columbia River blueback for the last 7 years. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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
