Mariculture: A global analysis of production trends since 1950

► Global mariculture production are re-estimated at a finer spatial and taxonomic scale. ► Mariculture data are spatially mapped in GIS to enhance analysis potential. ► A comparison of these data with FAO data yields comparable global and regional trends. ► Analysis of data confirms global and regional production at increasingly higher trophic levels. ► Erroneous data reporting, primarily from China, affect both global and local analyses.
