Fisheries driven evolution
Webselective evolution can be attributed to fisheries when heritable trait shifts of exploited fish stocks are a consequence of underly-ing genetic changes induced directly by fishing activity and thus not driven by the environmental nor trophic drivers (Kuparinen & Merilä, 2007). Although heavily harvested stocks often show trajec- WebPopulation genomic analysis using RAD sequencing or genome resequencing has been implemented for a few commercially important species, such as Asian sea bass , European sea bass , and Atlantic cod [22,26], revealing the genetic basis of fisheries-driven evolution and the possible repercussions of changes in the environment.
