Abstract
Abstract Routinely, fish encounter stressors and conditions that require the use of anaerobic exercise, including escaping predators, capturing prey, and interacting with fisheries. Although anaerobic metabolism rapidly yields energy to support locomotion, it also accelerates the depletion of energy stores, and accumulates potentially damaging metabolites, relative to aerobic metabolism. During recovery from intense exercise, animals are vulnerable and may forgo opportunities (e.g., foraging, mating). Recovery is thus likely under strong selection pressure. Despite the fact that recovery is essential for life, relatively little attention has been given to its importance for fitness and survival. Here, the ecology and physiology of recovery following intense exercise are reviewed using Pacific salmon (Oncorhynchus spp.) as a model, though findings are relevant to a wide range of species given that the need for recovery is ubiquitous. Specifically, when and why salmon use anaerobic exercise across their lifecycle, the physiological consequences of this extreme exercise, and the recovery process are considered. The importance of considering recovery for effective management and conservation of Pacific salmon species is discussed, and examples to highlight meaningful ways in which knowledge of recovery can be applied to problems facing fish are provided, with implications widely applicable to all fishes. Given current and projected climate scenarios, understanding the role of temperature in recovery will become progressively more important, and should be an explicit consideration when assessing vulnerability.
期刊介绍:
Reviews in Fisheries Science & Aquaculture provides an important forum for the publication of up-to-date reviews covering a broad range of subject areas including management, aquaculture, taxonomy, behavior, stock identification, genetics, nutrition, and physiology. Issues concerning finfish and aquatic invertebrates prized for their economic or recreational importance, their value as indicators of environmental health, or their natural beauty are addressed. An important resource that keeps you apprised of the latest changes in the field, each issue of Reviews in Fisheries Science & Aquaculture presents useful information to fisheries and aquaculture scientists in academia, state and federal natural resources agencies, and the private sector.
