This data is based on the following sources

Gephart et al. – Environmental performance of blue foods

This meta-study brings together life cycle inventory data (i.e., material and energy input and farm-level performance data) from studies of the environmental footprint of wild-caught and farmed seafood products. It draws on data from over 1690 farms and 1000 unique fishery records.

These impacts include those on-farm and off-farm, but stops at the farmgate (or landing of fish). This means it does not include impacts such as transport to retail, packaging, processing or cooking.

Impacts are normalised by the fish or seafood's edible weight (rather than their live weight).

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
