Among the traits that could evolve in response to fishing, growth has lately received attention. However, critical reading of the literature on growth evolution in fish reveals conceptual confusion about the nature of growth itself as an evolving trait, and about the different ways fishing can affect growth and size-at-age of fish, both on ecological and on evolutionary time-scales. It is important to separate the advantages of being big and the costs of growing to a large size, particularly when studying life-history evolution. In this review, we explore the selection pressures on growth and the resultant evolution of growth from a mechanistic viewpoint. We define important concepts and outline the processes that must be accounted for before observed phenotypic changes can be ascribed to growth evolution. When listing traits that could be traded-off with growth rate, we group the mechanisms into those affecting resource acquisition and those governing resource allocation. We summarize potential effects of fishing on traits related to growth and discuss methods for detecting evolution of growth. We also challenge the prevailing expectation that fishing-induced evolution should always lead to slower growth. 2012-03 published Wiley 10.1111/j.1439-0485.2011.00460.x XJ-12-013 Marine Eology; 33(1):1-25 (March 2012) (Published online 13 June 2011) [doi:10.1111/j.1439-0485.2011.00460.x] 1233 1224 122 public Marine Eology 33 1 1-25 TRUE 1439-0485 FALSE info:eu-repo/semantics/article
