Abstract

Abstract: Marine aquaculture (i.e. seafood farming in the ocean) has the potential to substantially support growing demand for animal protein. Despite vast amounts of suitable ocean space across the world, marine aquaculture development has been slow and geographically heterogeneous, indicating that factors other than suitable farming conditions are influencing industry growth. Using multivariate techniques, this study explores to what extent certain socioeconomic, governance, and biophysical factors can explain country-level patterns of mariculture production. We find that socioeconomic conditions are a significant contributor to whether a country produces mariculture and the magnitude of its production; our models explain up to 33% more of the variation in mariculture production compared to models including only biophysical parameters. These results are relatively consistent across types of mariculture production (i.e. finfish, crustaceans, molluscs, and algae). Our findings suggest that improving seafood farming infrastructure, creating local demand for seafood, and facilitating knowledge transfer from land-based and freshwater aquaculture could help countries develop stronger mariculture industries.
