Download or read book Physiological Stress in Native Brook Trout Salvelinus Fontinalis During Episodic Acidification of Streams in the Great Smoky Mountains National Park written by and published by . This book was released on 2007 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Episodes of stream acidification are suspected to be the primary cause of the extirpation of native southern brook trout (Salvelinus fontinalis) from six headwater streams in the Great Smoky Mountains National Park (GRSM). During periods of increased flow from storm events, stream pH can drop below 5.0 (minimum of 4.0) for 2-days or longer. To provide evidence that native brook trout are impacted by stream acidification, in situ bioassay experiments were conducted. Changes in stream water chemistry and brook trout physiology were determined during a 36-hour acidic episode at three remote headwater stream sites in the Middle Prong of the Little Pigeon River watershed. Conductivity, pH, turbidity, stage height and temperature were monitored continuously; and water samples were collected for laboratory analyses (metals, cations, anions, ANC). Native brook trout were put in cages at the three sites and fish were sampled before and after the acid storm event. Physiological stress in brook trout was assessed by measuring whole-body sodium in individual fish sampled before and after the stormflow, and evaluating whole-body sodium loss as a response to acid conditions. The pH decreased at all three sites during the acidic episode. Stream pH dropped to approximately 5.0 at two sites and 4.66 at the third site. Prior to the storm, there was no difference in the whole-body sodium concentrations in trout between the three sites. Following the storm event, in trout from the site that experienced the lowest pH, whole-body sodium levels were reduced significantly relative to a) the pre-storm condition and b) trout from the other sites. Results demonstrate that stream acidification can negatively affect native southern brook trout physiology in the GRSM under actual field conditions. Trout lose the ability to regulate critical blood ions, as exemplified by a loss of whole-body sodium, when stream pH was less than 5.0 for 20 hours. Loss of sodium is an important indication of physiological stress in fish exposed to acid waters. This observation supports the hypothesis that episodic acidification of streams could be limiting native brook trout from occupying headwater streams in the GRSM.

Download or read book Acid Toxicity and Aquatic Animals written by R. Morris and published by Cambridge University Press. This book was released on 1989-03-16 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews and presents recent research on acid waters and their effects on aquatic animals. Starting with the environment, in order to assess why the problems have arisen in particular areas, the volume then deals with field and survival studies on invertebrates and vertebrates; examines the extent of the biological problem and the attempts that have been made to relate water quality and the susceptibility of animals. The natural progression of environmental and field studies, toxicity, and survival tests provide the background information for the physiological studies that follow. These form the major component of the book and they seek to analyze the toxic effects of acid waters and trace metals with cardiovascular and endocrinological effects.
Download or read book Fish Physiology Homeostasis and Toxicology of Non Essential Metals written by and published by Academic Press. This book was released on 2011-07-01 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homeostasis and Toxicology of Non-Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Ag, Al, Cd, Pb, Hg, As, Sr, and U have no known nutritive function in fish at present, but are toxic at fairly low levels. The companion volume, Homeostasis and Toxicology of Essential Metals, Volume 31A, covers metals that are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr. In addition, three chapters in Volumes 31A and 31B on Basic Principles (Chapter 1, 31A), Field Studies and Ecological Integration (Chapter 9, 31A) and Modeling the Physiology and Toxicology of Metals (Chapter 9, 31B) act as integrative summaries and make these two volumes a vital set for readers. - All major essential metals of interest are covered in metal-specific chapters - Each metal-specific chapter is written by fish physiologists/toxicologists who are recognized authorities for that metal - A common format is featured throughout this two volume edition

Download or read book Recent Advances in Aquaculture written by J.F. Muir and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of the previous volumes in this series attests to the buoyancy of the current expansion of the aquaculture industry, and the importance which it is beginning to achieve in the rural economies of many developed countries as well as those less favoured. In the last volume, emphasis was given to certain specialist areas which had become more important as the industry had acquired a more sophisti cated scientific base. This emphasis is continued, but in each of the chapters of the present volume there are, we believe, many data of general significance to the farmer and the project manager as well as to the pro fessional aquaculture scientist. David Alderman, of the English Ministry of Agriculture, Fisheries and Food Laboratories, at Weymouth, Dorset, provides a very detailed and deeply researched review of therapy of fish diseases. This subject is import ant in environmental and human health terms as well as in relation to the fish themselves, and is an area where all farmers, and their professional veterinary advisers, require considerable knowledge if they are to ensure the reputation of the industry and its produce.

This book was released on 2012-12-06 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic envi ronments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international pUblications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on ''toxic'' chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxi cology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature produced by these emerging areas of science together with docu mentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individu als need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching.
