In other words, we treat all countries recognized in 2010 by the international community (or acting like independent entities with regards to fisheries, e.g., the divided island of Cyprus; Ulman 2014) as having existed from 1950-2010.

Catches that are not associated with tuna and other large pelagic fishes, but taken by fishing countries outside their domestic waters are derived as described for ‘Layer 2’ in Part 4.
based on the fundamental principles outlined in UNCLOS (i.e., 200 nautical miles or mid-line rules), and the FAO statistical areas by which global catch statistics are reported.
As FAO assembles and harmonizes data from various sources, this first-order comparison enabled catches ‘taken elsewhere’ to be identified and separated from truly domestic (national EEZ) fisheries (see Part 4 for the spatial layering of reconstructed datasets).
For some countries, e.g., those resulting from the breakup of the USSR, and Yugoslavia, this involved sourcing data that the now-newly emerged countries would have reported, had these countries already existed independently in 1950.
What is covered here are catches in the waters within the Exclusive Economic Zones (EEZ, Figure 1) that countries have claimed since they could do this under the United Nations Convention on the Law of the Sea (UNCLOS), or which they could claim under UNCLOS rules, but have not (such as many countries around the Mediterranean).
strives to provide time-series of all marine fisheries catches since 1950, the first year that the Food and Agriculture Organization of the United Nations (FAO) produced its annual compendium of global fisheries statistics. These maps are drawn on the basis of the best information available to us. Note that we: : Maritime limits and boundaries depicted on Sea Around Us maps are not to be considered as an authority on the delimitation of international maritime boundaries.This also applies to islands and other territories, many of which were colonies, and which have changed status and borders since 1950. Conceptual representation of the 7-step catch reconstruction approach, as initially described in Zeller (2007) and modified here.For several countries, the baseline was provided by other international bodies.Searching on FIRE: You can use the browser FIND command to search for words on a specific page, or you can do a Google site search of the entire FIRE web site.
