Fish Stocks Relative

this graph was created in ramlegacy :

Fish stocks relative to the maximum sustainable yield

Fish stocks are measured by their biomass: the number of individuals multiplied by their mass.
Here it's measured as the biomass of a fish stock divided by the biomass at its maximum sustainable yield – the level at which we can
catch the maximum amount of fish without a decline in fish populations. A value of one maximises fish catch without decreasing fish
populations.

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.
