Energy Consumption: Metabolism (General)

Standard metabolic rate, SMR, or the totality of energy-consuming, manipulative and storage chemical reactions undertaken by fish to maintain life is the topic of this article. The factors that account for SMR and measurement theory are considered. Despite decades of effort, there is no universal method for measuring SMR, and various methods and general problems with measuring are discussed. One of the most important factors contributing to differences in SMR is body size. Despite considerable effort, there is still uncertainty in how metabolism scales in fish. Other factors that contribute to SMR such as species, population origin, genetics and season are also discussed.
