Global meals demand is rising, and serious questions stay about whether or not grant can extend sustainably1. Land-based growth is viable however may additionally exacerbate local weather trade and biodiversity loss, and compromise the transport of different ecosystem services2-6. As meals from the sea represent solely 17% of the present day manufacturing of safe to eat meat, we ask how a great deal meals we can count on the ocean to sustainably produce through 2050. Here we have a look at the foremost food-producing sectors in the ocean-wild fisheries, finfish mariculture and bivalve mariculture-to estimate ‘sustainable provide curves’ that account for ecological, economic, regulatory and technological constraints. We overlay these grant curves with demand eventualities to estimate future seafood production. We discover that below our estimated demand shifts and provide eventualities (which account for coverage reform and technological know-how improvements), fit to be eaten meals from the sea may want to amplify through 21-44 million tonnes through 2050, a 36-74% amplify in contrast to cutting-edge yields.
