6.3 EUROSTAT internal consistency

Ideally there should be internal consistency within the EUROSTAT data on catches and landings. Here we check this.

6.4 EUMOFA vesus EUROSTAT Landings

Ideally, the EUMOFA data should also agree very closely with the EUROSTAT landings data. Here we check these assumptions.

6.5 Nearest Neighbour Assumption

In order to relate the landings in a region (EUMOFA data) to the hazard of a stock, we need to know where these landings were caught. We make the assumption here that all landings in EUMOFA are from the adjacent FAO subarea. We can check the validity of this “nearest neighbour” assumption by calculating the landings per stock per country that this implies and comparing it to the EUROSTAT catch data (catch per stock per country)
