Fisheries exploitation can cause genetic changes in heritable traits of targeted stocks. The direction of selective pressure forced by harvest acts typically in reverse to natural selection and selects for explicit life-histories, usually for younger and smaller spawners with deprived spawning potential. While the consequences that such selection might have on the populational dynamics of a single species are well emphasised, we are just beginning to perceive the variety and severity of its propagating effects within the entire marine food webs and ecosystems. Here, we highlight the potential pathways in which fishing-induced evolution, driven by size-selective fishing, might resonate through globally connected systems. We look at: i) how a size-truncation may induce shifts in ecological niches of harvested species, ii) how a changed maturation schedule might affect the spawning potential and biomass flow, iii) how changes in life-histories can initiate trophic cascades, iv) how the role of apex predators may be shifting, and v) whether fishing-induced evolution could co-drive species to depletion and biodiversity loss. Globally increasing effective fishing effort and the uncertain reversibility of eco-evolutionary change induced by fishing necessitate further research, discussion, and precautionary action considering the impacts of fishing-induced evolution within marine food webs. ...

Implications of size‐selective fisheries on sexual selection Uusi-Heikkilä, Silva (Wiley-Blackwell, 2020)Fisheries often combine high mortality with intensive size‐selectivity and can, thus, be expected to reduce body size and size variability in exploited populations. In many fish species, body size is a sexually selected ...
Fishing triggers trophic cascade in terms of variation, not abundance, in an allometric trophic network model Uusi-Heikkilä, Silva; Perälä, Tommi; Kuparinen, Anna (Canadian Science Publishing, 2022)Trophic cascade studies often rely on linear food chains instead of complex food webs and are typically measured as biomass averages, not as biomass variation. We study trophic cascades propagating across a complex food ...
Exploring individual and population eco-evolutionary feedbacks under the coupled effects of fishing and predation Jusufovski, Dunja; Kuparinen, Anna (Elsevier BV, 2020)Intensive fishing that selects for large and old individuals can have pervasive effects on traits directly associated with the fecundity and survival of the target species. The observed reduction in fish body size can ...
Limited effects of size-selective harvesting and harvesting-induced life-history changes on the temporal variability of biomass dynamics in complex food webs Nonaka, Etsuko; Kuparinen, Anna (Elsevier, 2023)Harvesting has been implicated in destabilizing the abundances of exploited populations. Because selective harvesting often targets large individuals, some studies have proposed that exploited populations often experience ...
Experimental size-selective harvesting affects behavioral types of a social fish Sbragaglia, Valerio; Alós, Josep; Fromm, Kim; Monk, Christopher T.; Díaz-Gil, Carlos; Uusi-Heikkilä, Silva; Honsey, Andrew E.; Wilson, Alexander D.M.; Arlinghaus, Robert (John Wiley & Sons Ltd., 2019)In most fisheries, larger fish experience substantially higher mortality than smaller fish. Body length, life-history and behavioral traits often correlate, such that fisheries-induced changes in size or life-history can ...
