Selection for Vulnerability to Angling in Largemouth Bass (2009, unknown): “In recent years, numerous studies have documented fishing-induced selection in commercially exploited marine fishes (e.g., Stokes and Law 2000; Heino and Godø 2002; Olsen et al. 2005).”
Integrating Reproductive Biology into Scientific Advice for Fisheries Management (2008, background): “Increased mortality can select for maturation at a younger age (Diana, 1983; Roff, 1992; Hutchings, 1993; Fox, 1994; Olsen et al., 2005) and smaller size (Kasperski and Kozlowski, 1993).”
Fishing effects on age and spatial structures undermine population stability of fishes (2009, background): “Empirical studies suggested that fishing-induced age (size) truncation may be responsible for the collapse of Atlantic cod stock off Newfoundland (Olsen et al. 2004, 2005), recruitment failure of the Arcto-Norwegian cod stock (Ottersen et al. 2006), declined lifetime egg production for rockfishes (O”
Correlates of recovery for Canadian Atlantic cod (Gadus morhua) (2011, background): “Concomitant with reductions in abundance have been significant changes in life-history traits (Trippel et al. 1997; Olsen et al. 2005; Brattey et al. 2008; Fudge and Rose 2008).”
Life history consequences of overexploitation to population recovery in Northwest Atlantic cod (Gadus morhua) (2005, result): “Rather the data are consistent with the hypothesis that earlier age and smaller size at maturity are best explained as genetic responses to fishing-induced selection against late-maturing, and large-maturing, genotypes (Hutchings 1999; Olsen et al. 2004, 2005).”
Taking account of catchability in groundfish survey trawls: implications for estimating demersal fish biomass (2007, background): “This approach has obvious problems given that catchability in the GOV was always likely to be size-dependent (Harley and Myers, 2001; Benoı̂t and Swain, 2003), and because there is clear evidence of changes in the size structure of the North Sea demersal fish assemblage, both within and between spec”
Ocean's eleven: a critical evaluation of the role of population, evolutionary and molecular genetics in the management of wild fisheries (2015, background): “After centuries of exploitation, Atlantic cod life histories have shifted towards maturation at earlier stages and smaller sizes in spite of environmental conditions favouring the opposite (Olsen et al. 2005; Swain et al. 2007).”
Paradigm shifts in marine fisheries genetics: ugly hypotheses slain by beautiful facts (2008, background): “…1995), Atlantic cod also became one of the case studies for demonstrating fishery-induced evolution from probabilistic maturation reaction norms (Olsen et al. 2004, 2005), although the inferences of genetic changes have been questioned extensively (Kuparinen and Merilä 2007; Law 2007; Browman…”
Detecting Fisheries-Induced Life-History Evolution: An Overview of the Reaction-Norm Approach (2008, methodology): “…has become the most frequently used estimation method for pMRNs and has been applied successfully to several stocks of cod (Barot et al., 2004b; Olsen et al., 2004, 2005) and American plaice [Hippoglossoides platessoides (Fabricius, 1780); Barot et al., 2005] in the northwest Atlantic, as well…”
Probabilistic maturation reaction norms: their history, strengths, and limitations (2007, unknown): “…forward, for example, by Polovina (1989; in the Hawaiian spiny lobster Panulirus marginatus: size at onset of egg production declined even though population density decreased) and by Olsen et al. (2005; in northern cod Gadus morhua: age at maturation declined even though growth rates decreased).”
