Aquaculture will continue to depend more on land than sea

arising from C. Costello et al. Nature https://doi.org/10.1038/s41586-020-2616-y (2020)

Costello et al. 3 overestimate current mariculture production and future production potential, and underestimate freshwater aquaculture production and potential in six ways by: (1) defining brackishwater aquaculture as part of mariculture; (2) excluding crustaceans from their model; (3) conflating freshwater capture fisheries and freshwater aquaculture production; (4) making projections of marine bivalve production that are inconsistent with historical trends; (5) making over-optimistic assumptions about marine finfish farming technologies; and (6) not accounting for high potential to raise freshwater aquaculture yields through intensification (see Supplementary Information, section 1 for full details).
