Fish flow among EU States
By @benjamesdavis

...Based on ICES landings data (2016), in which each EU state reports its catches across a grid of spatial cells.

By clipping this grid against the Exclusive Economic Zone (EEZ) polygon of each state, we can infer the country of origin of landed fish, and link this with the nationality of the fleet that caught them.

1200k tonnes (49%) of EU catches come from UK waters

...of which 34% is caught by UK fleets.

...and the rest is split between 5 other EU states

${showMap(mapColor)}

where fish are caught

who's catching them
