Fisheries-induced evolution of behavior: Experimental evidences from size-selective harvesting of zebrafish
Intensive and selective fishing can evolutionary alter life-history, physiological and behavioral traits, thereby affecting population dynamics. Fisheries-induced evolution may also change carrying capacity, yield, reference points, catchability and recovery and it is thus relevant from a fisheries-management perspective. Most research on fisheries-induced evolution has focused on life history adaptation, with much less attention devoted to the evolution of behavioral and physiological traits. I will present results related to multi-generational experimental system based on zebrafish (Danio rerio) lines adapted to large, small or random (i.e. control) size‐selective mortality. I will provide evidences for harvesting-induced evolution of several behavioral traits including: (i) individual personality traits, (ii) mating behavior, (iii) collective personality traits, and (iv) circadian rhythms. My research substantially advances the field of fisheries-induced evolution revealing new mechanisms driving behavioral adaptation and new intriguing hypothesis to be tested in natural systems
