Book Synopsis Nitrogen Metabolism and Excretion by : Patrick J. Walsh
Download or read book Nitrogen Metabolism and Excretion written by Patrick J. Walsh and published by CRC Press. This book was released on 1995-08-31 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the basic evolutionary patterns of nitrogen metabolism and excretion have been outlined for decades, there has been a resurgence of research activity in the past 15 years. Research in nitrogen metabolism has been stimulated in the area of acid-base balance. The molecular revolution has had an impact on the field as well, and recent studies on nitrogen metabolism and excretion now almost routinely use the tools of molecular biology. Of special interest are recent studies of evolutionary relationships between proteins of nitrogen metabolism. Nitrogen Metabolism and Excretion updates the reader on progress being made in this subject, offering an exciting integration of traditional topics and discussions on the most recent issues which have not yet appeared in other textbooks or references. The book features chapters on the latest developments in nitrogen metabolism and excretion from 28 prominent researchers from all over the world. Each chapter is detailed and specific, filled with useful concepts and techniques. The scope of the book is broad and diverse, covering groups from invertebrates to mammals, and subjects from nitrogen in oceanic buoyancy regulation to molecular mechanisms of nitric oxide synthesis. The text provides a phylogenetic view of various animal groups and presents much new information intended to break down phylogenetic stereotypes. The general areas of development, maternal-fetal interactions, protein turnover, carbamoyl phosphate synthesis, nitric oxide, and nitrates and nitrites are also covered in depth. This volume is the first in a new series that brings about a modern synthesis of areas of animal physiology. Nitrogen Metabolism and Excretion benefits both established researchers interested in nitrogen and advanced undergraduate and graduate students who want to investigate the most current and exciting questions being studied and debated.
Book Synopsis Effects of Accumulated Excretory Products on Hatchery-reared Salmonids by : Roger E. Burrows
Download or read book Effects of Accumulated Excretory Products on Hatchery-reared Salmonids written by Roger E. Burrows and published by . This book was released on 1964 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: In experiments at the Bureau's Salmon-Cultural Laboratory, to determine the excretory products of significance in rearing ponds and the possible effect of these products on fingerling chinook salmon (Oncorhynchus tshawytscha), the results demonstrated that ammonia and urea are the principal products. The relative amounts of these products vary with the concentration of fish and with their metabolic activity. Ammonia assumes dominance in an unfavorable environment. Water temperature, pH, and pond type affect the toxicity of ammonia solutions. Continuous exposure to levels of ammonia normally encountered in rearing ponds produced extensive hyperplasia of the gill epithelium in controlled experiments.

Book Synopsis Fish Larval Physiology by : Roderick Nigel Finn
Download or read book Fish Larval Physiology written by Roderick Nigel Finn and published by CRC Press. This book was released on 2020-04-30 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the singlecelled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution. The book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.

Book Synopsis Intraspecific Variation in Nutrient Excretion by Fish by : Christopher Michael Dalton
Download or read book Intraspecific Variation in Nutrient Excretion by Fish written by Christopher Michael Dalton and published by . This book was released on 2015 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient excretion by consumers can alter ecosystems by changing the availability of limiting nutrients. Understanding controls on nutrient excretion is thus necessary to predict ecological dynamics. Ecological stoichiometry predicts nutrient excretion rates based on the principles of homeostasis and mass balance, and this theoretical framework effectively explains variation in excretion among fish species. It fails, however, to explain the substantial variation in excretion within species. This dissertation uses a model species for trait variation, the Trinidadian guppy (Poecilia reticulata), to explore why ecological stoichiometry has fared so poorly in explaining intraspecific variation in excretion. I first used a lab study to assess traditional stoichiometric predictions for nutrient excretion. This study found the expected stoichiometric patterns for phosphorus excretion, but not for nitrogen excretion. A field survey supported these results, and it indicated that the presence of a predatory fish, Crenicichla frenata, explained variation in guppy nitrogen excretion. In ensuing lab studies, I sought to isolate the influence of predation risk on nitrogen excretion by rearing guppies with or without the chemical cues of this predatory fish. This approach highlighted that predator cues reduced guppy nitrogen excretion by nearly 40%, primarily by reducing food intake. Standardizing for food intake, however, revealed that predator cues reduced guppy excretion more than food consumption. Guppies with predator cues thus excreted a smaller fraction of consumed nitrogen, retaining nitrogen more efficiently. We suggest that reduced nitrogen excretion under predation risk reflects a wasteminimizing physiology similar to that caused by extended food deprivation. We show, however, that food deprivation takes up to 14 days to change guppy physiology, while predation risk induces even greater metabolic change within just 24 h. This result raises the possibility that guppies use predation risk as a signal of impending food restriction, immediately inducing metabolic changes to increase retention of nutrients for future needs. In summary, this dissertation highlights that ecological stoichiometry can explain variation in phosphorus excretion but not nitrogen. Nitrogen excretion is better described by models incorporating causes of variation in metabolism. Predation risk, a major influence on consumer metabolism, is likely central to intraspecific variation in nitrogen excretion.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a comprehensive overview on the diverse strategies invertebrate animals have developed for nitrogen excretion and maintenance of acid-base balance and summarizes the most recent findings in the field, obtained by state-of-the-art methodology. A broad range of terrestrial, freshwater and marine invertebrate groups are covered, including crustaceans, cephalopods, insects and worms. In addition the impact of current and future changes in ocean acidification on marine invertebrates due to anthropogenic CO2 release will be analyzed. The book addresses graduate students and young researchers interested in general animal physiology, comparative physiology and marine/aquatic animal physiology. Also it is an essential source for researchers dealing with the effects of increasing pCO2 levels on aquatic animals, of which the vast majority are indeed invertebrates. All chapters are peer-reviewed.
Book Synopsis Nutrient Dynamics in Freshwater Fish Culture System by : C.B.T. Rajagopalsmy
Download or read book Nutrient Dynamics in Freshwater Fish Culture System written by C.B.T. Rajagopalsmy and published by Daya Books. This book was released on 2002-04 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quality seed, feed and fertilizer are known to decree target fish yield in any type of aquaculture system. Among these vital factors, the right type and input schedule of fertilizers have gathered much scientific concern. Obviously, phosphorus the major limiting nutrient of freshwater culture system has been studied in detail by various workers. However, there is brevity of information on the colossal loss of money encountered by the fisheries sector engrossed in freshwater culture due to the transformation of phosphatic fertilizers into non-recyclable apatite phosphorus. This book provides the first hand information on the utilization of sodium tripolyphosphate in hard water fish culture system for relegating the formation of apatite. The merit of such investigations lie in the fact that the development of a proper phosphatic fertilization schedule for hard water will hold good for brackishwater fish pond also. The results of the present investigation affirm the fact that apatite occurs as the second major constituent of total sedimentary phosphorus. Though the chemical reactions leading to the formation of apatite in aquatic ecosystems remain as a riddle, many of the field trials fortify the operation of the phenomenon of apatite formation in aquaculture system. The present study focuses its prime attention over this crucial reality and advocates the benefits of utilizing sodium tripolyphosphate as a phosphatic fertilizer in aquaculture system. The authors are convinced that intensive field trails in this regard would pave way for the most aspired blue revolution.
