Figure 2.

Comparison of total greenhouse gas emissions across all stages of the mariculture supply chain for bivalve, fed finfish and seaweed (excluding post harvest transport emissions). Emissions are reported in kilograms of carbon dioxide equivalents (CO₂e) per metric ton live weight harvested. 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 have been omitted from the plot (for ease of viewing). Data were collated through our literature search for each sector and are available in supplemental tables S1 and S3.
