How close to maximum sustainable food provision is current seafood harvest from the world’s oceans? Halpern et al. [1] suggest that the answer is 25% from a global index of food provision, part of their multifaceted index of ocean health.

Phenotype flexibility in wild fish: Dolly Varden regulate assimilative capacity to capitalize on annual pulsed subsidies.
J Anim Ecol. 2013 Mar 19;
