Also, our results indicate without fish, world will face a food shortage 71 million tonnes annually 2030, rate would 3 times current average projected FAO, World Bank OECD 2030. Finally, geographical distribution farmed suggests even if physically, economically, technically ecologically feasible, its socio-economic cost low-income coastal countries could devastating.
