Climate-driven change in pelagic production , together with overfishing, will likely increase risks for fishery landings . By 2060, more than 20% of exploited fishes and invertebrates currently found in eastern Mediterranean could become locally extinct . Thermophilic and/or thermal-tolerant tropical species may increasingly dominate the catch composition , creating possible opportunities depending on technology and consumer acceptance of new species . Warming and acidification may weaken mussel shells, negatively impacting shellfish aquaculture . High losses of clawed lobster production by the end of the century are projected under RCP4.5 . For much of the region, fisheries revenue may decrease by 15-30% by 2050 relative to 2000 under RCP8.5 .
