Summary of greenhouse gas emissions from fed finfish mariculture reported in kilograms of carbon dioxide equivalents (CO2e) per ton live weight harvested (excluding post harvest transport emissions). Data were collated from existing studies and, where possible, have been grouped into upstream, on-farm and downstream activities and separated by production system type (all systems pooled, closed or recirculating systems and open net pen systems). The bold horizontal line in each box shows the median value, the box extents are the upper and lower quartiles, whiskers extend to 1.5 times the interquartile range and outliers are shown by black points.
