Abstract
Climate change is among the most serious environmental challenge facing humanity and the ecosystems that provide the goods and services on which it relies. Climate change has had a major historical influence on global biodiversity and will continue to impact the structure and function of natural ecosystems, including the provision of natural services such as fisheries. Freshwater fishery professionals (e.g. fishery managers, fish biologists, fishery scientists and fishers) need to be informed regarding the likely impacts of climate change. Written for such an audience, this chapter reviews the drivers of climatic change and the means by which its impacts are predicted. It details observed and future predicted effects of climate change on freshwater ecosystems across Arctic, temperate and tropical climatic zones and highlights those areas where data are currently limiting our understanding of how and if climate change is affecting freshwater fisheries. Observed and predicted consequences of climatic change on the ecology of freshwater fishes are examined at different levels of biological organization, including individual, population, community and ecosystem levels, and future scenarios are discussed. The chapter examines the likely impacts of such changes on the exploitation and management of freshwater fishes across recreational, artisanal and commercial fishery sectors, including observations on the vulnerability of fishers themselves to climate change.
