No abstracts are to be cited without prior reference to the author.In many commercially important fish stocks, fishing induced mortality can be several times higher than natural mortality. If fishing is sizeselective, it will disproportionally decrease survival of fastest growing and largest individuals, leading to fisheries induced evolution (FIE). Empirical data from wild fish stocks and theoretical models show strong support that FIE is already happening (Figure 1) and might be having negative impact on recovery of heavily exploited stocks. Yet, nothing is known about the ecosystem level consequences of FIE ...
