In der Fischerei sind viele Fanggeräte so konzipiert, dass die großen Fische ins Netz gehen, während die kleineren entkommen können. Die sogenannte größenselektive Fischerei kann Computermodellen zufolge in wenigen Generationen das Wachstumspotenzial der überlebenden Fische reduzieren und ihr Verhalten verändern. Ob die Auswirkungen der Fischerei bis in die Gene zurückverfolgt werden können, wird jedoch kontrovers diskutiert. Eine experimentelle Studie des Leibniz-Instituts für Gewässerökologie und Binnenfischerei (IGB) und der Universität Turku (Finnland) weist nun nach, dass die stete Entnahme der größten Individuen aus einem Fischbestand tatsächlich Veränderungen in der Aktivität von Tausenden Genen nach sich zieht.
