Evolutionary impacts of fishing: overfishing's 'Darwinian debt' [PDF]
F1000 Biology Reports, 2009 Human harvesting of fish results in far greater mortality than natural causes, with enormous potential to affect the phenotypic traits of fish populations, even after exploitation stops. Central to understanding these effects is the untangling of the genetic versus environmental components of phenotypic response. Evolutionary consequences of harvesting
