The Mediterranean and Black Sea list of stocks to be used for computing the indicators was based on a ranking system approach for which the species having a rank in the first ten positions either in total live weight or total economic values were chosen.
Landings and economic values for the Mediterranean and Black Sea (FAO area 37) provided by “2016_STECF 16-11 - EU Fleet Economic and Transversal data tables” were used.
The reference years were 2012 and 2014 (the last three years available for all the GSAs) and, as geographic strata, the Geographical Sub Areas (GSAs) belonging to EU countries and for which data were available were considered.
In the top ranking 10 stocks based on both in terms of live weight and economic value by GSA applied to AER Landings, many combined/nei groups categories were selected.
Based on local expert knowledge it was possible split some mixed categories at species level while, it was decided to drop from the list both the misreporting species and the mixed categories for which it wasn't possible defined clearly the species composition.
Eventually 230 stocks were selected.JRC.D.2-Water and Marine Resource
