Metabolic rate suppression as a mechanism for surviving environmental challenge in fish.
The ability to reduce metabolic rate during exposure to environmental stress, termed metabolic rate suppression, is thought to be an important component to enhance survival in many organisms. Metabolic rate suppression can be achieved through modifications to behavior, physiology, and cellular biochemistry, all of which act to reduce whole organisms energy expenditure. This chapter will critically evaluate the use of metabolic rate suppression as a response to environmental challenge in fish using three metabolic states: aestivation, hypoxia/anoxia exposure, and diapause.
