TLDR
The chapter focuses on the action of the environment on metabolism and the effects of this action on the activity of the organism.Abstract:
The study of animal function is organized more or less under three heads, which in everyday language are, as applied to a machine, what it can do, how it works, and what makes it go. Insofar as fields of study can be classified in biology these divisions of the subject are ordinarily considered to be autecology, physiology, and biochemistry, with a great deal of individual taste governing the label any particular worker may choose for himself. The chapter discusses what fish can do in relation to their environment and therefore largely autecology. The chapter focuses on the action of the environment on metabolism and the effects of this action on the activity of the organism.read more

6 – Physiological Energetics
J.R. Brett,T.D.D. Groves +1 more
TL;DR: An understanding of the physical, chemical, and biological basis on which the energetics is built, and the equivalents employed, constitutes the opening section of this chapter.

10 - Environmental Factors and Growth
TL;DR: The individual functions have been introduced in the chapter to provide some explanation of the response to environmental factors, without deviating from the major purpose of examining the recorded trends in the activity of growing.
Journal ArticleDOI
Temperature as an Ecological Resource
TL;DR: It is suggested that viewing temperature and other niche axes in the way ecologists have viewed food resources would be useful, and if animals successfully compete for their thermal niche, growth and perhaps other measures of fitness are maximized.

Potential impacts of global climate change on freshwater fisheries
TL;DR: Model predictions indicate that global climate change will continue even if greenhouse gas emissions decrease or cease, and proactive management strategies such as removing other stressors from natural systems will be necessary to sustain freshwater fisheries.
Journal ArticleDOI
Energy Homeostasis as an Integrative Tool for Assessing Limits of Environmental Stress Tolerance in Aquatic Invertebrates
TL;DR: It is proposed that energy-related biomarkers can be used to determine the conditions when these metabolic transitions occur and thus predict ecological consequences of stress exposures, and assist in explaining and predicting the species' distribution limits in the face of the environmental change and informing the conservation efforts and resource management practices.

The Respiratory Metabolism and Swimming Performance of Young Sockeye Salmon
TL;DR: Rate of replacement of oxygen debt following fatigue was determined by tracing the return to a resting state of metabolism, and confirmed by re-tests at fatigue velocities, and in most instances the rate declined logarithmically with time.
Journal ArticleDOI
The theory of open systems in physics and biology.
TL;DR: An extension and generalization of the principles of physics and physical chemistry, complementing the usual theory of reactions and equilibria in closed systems, and dealing with open systems, their steady states, and the principles governing them are needed.
Journal ArticleDOI
The calculation of the dosage-mortality curve
TL;DR: It is shown that when dosage is inferred from the observed mortality on the assumption that susceptibility is distributed normally, such inferred dosages, in terms of units called probits, give straight lines when plotted against the logarithm of their corresponding observed dosages.

Growth Rate and Body Composition of Fingerling Sockeye Salmon, Oncorhynchus nerka, in relation to Temperature and Ration Size
TL;DR: The growth of young sockeye salmon was studied at temperatures ranging from 1 to 24 C in relation to rations of 0, 1.5, 3, 4, 5, and 6% of dry body weight per day, and at an "excess" ration.
