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

This book was released on 2013-03-09 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: What, precisely, is a primitive fish? Most biologists would agree that the living cyclostomes, selachians, crossopterygians, etc. cannot be considered truly primitive. However, they and the fossil record have served to provide the information which forms the basis for speculation concerning the nature of the original vertebrates. This symposium of biologists from a variety of disciplines was called together to create collectively, from the best available current evidence, a picture of the probable line of evolution of the prototype primitive fishes. The symposium was designed to follow one that took place in Stockholm in 1967, convened for a similar purpose, with about the same number of participants. It is a matter of interest that almost the entire 1967 symposium (Nobel Symposium 4) dealt only with the hard tissues, whether fossil or modern. In charting the course of the present symposium it was felt that the intervening years have produced numerous lines of new evidence that could be employed in the same way that a navigator determines his position. Each field, be it adult morphology, geology, ecology, biochemistry, development or physiology, generates evidence that can be extrapolated backward from existing vertebrate forms and forward from invertebrate forms. If the intersect of only two lines of evidence produces a navigational "fix" of rather low reliability, then an intersect, however unfocussed, of multiple guidelines from more numerous disciplines might provide a better position from which to judge early vertebrate history.

Download or read book Jawless Fishes of the World written by Richard Beamish and published by Cambridge Scholars Publishing. This book was released on 2016-02-29 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hagfishes and lampreys, both examples of jawless fishes, are elongated, eel-like animals lacking paired fins, and are the only living representatives of ancient creatures that gave rise to current species of fish and, eventually, humans. This volume provides an overview of the current status of knowledge on a variety of topics related to jawless fishes, including their taxonomy, zoogeography, phylogeny, molecular biology, evolution, life history, role in the ecosystem, and fisheries and management of hagfishes and lampreys worldwide. This is the first book dealing exclusively with the various aspects of jawless fish species throughout the world. It brings together a number of papers providing new data on jawless fishes, and offers readers a range of useful information within a single reference, reflecting the growing appreciation for hagfishes and lampreys worldwide.
