Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using histochemical and histopathological changes in brook trout, longnose dace and fathead minnows as bioindicators of acid pollution was investigated. Laboratory studies entailed using a gravity flow diluter system. Field studies involved using net traps in polluted streams. Exposure durations were 4-5 days and 28-30 days. Histochemical and cytophotometric analyses were made of gills, Stannius corpuscle, blood, spleen, kidney and liver. The primary mode of acid toxicant action is gill damage which results in impaired respiratory, excretory and liver functions. Short term indices of acid stress include: colloidal iron and aminosalicylic acids (PAS) staining of gills and renal Stannius corpuscles. A useful bioindicator of prolonged acid exposure is decreased azure B-RNA staining of liver cells; this assesses the extent of liver impairment and reflects a reduced tolerance of fish to other toxicants.
Download or read book Conservation Physiology for the Anthropocene A Systems Approach written by and published by Academic Press. This book was released on 2022-10-21 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Physiology for the Anthropocene: A Systems Approach, Volume 39A in the Fish Physiology series, is a comprehensive synthesis on the physiology of fish in the Anthropocene. This volume closes the knowledge gap by considering the many ways in which different physiological systems (e.g., sensory physiology, endocrine, cardio-respiratory, bioenergetics, water and ionic balance and homeostasis, locomotion/biomechanics, gene function) and physiological diversity are relevant to management and conservation. As the world is changing, with a dire need to identify solutions to the many environmental problems facing wild fish populations, this book comprehensively covers conservation physiology and its future techniques. Conservation physiology reveals the many ways in which environmental change and human activities can negatively influence wild fish populations. These tactics inform new management and conservation activities and help create the necessary conditions for fish to thrive. - Presents authoritative contributions from an international board of authors, each with extensive expertise in the conservation physiology of fish - Provides the most up-to-date information on the ways in which different physiological systems are relevant to the management and conservation of fish and fisheries - Identifies how anthropogenic stressors perturb physiological systems - Explores how different physiological systems can be exploited to solve conservation problems

Download or read book Leeches Lice and Lampreys written by Graham C. Kearn and published by Springer Science & Business Media. This book was released on 2007-11-05 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.
Download or read book Tilapias Biology and Exploitation written by M.C.M Beveridge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.
Download or read book Developmental Biology of Teleost Fishes written by Yvette Kunz-Ramsay and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the compiling of this book, the vast literature dealing with the descriptive morphology, histology and cytology of teleost development has been combed and integrated. The book is divided into 21 chapters, starting with the egg and embryonic development up to hatching. This is followed by a description of ectodermal, mesodermal and entodermal derivatives and the development of various organs. The subject index, species index and the abundant illustrations add extra value to this long awaited book. Developmental Biology of Teleost Fishes will be a valuable tool for scientists and students in the fields of biology, developmental biology, molecular biology and fish biology.
