19 of the 33 countries included in the High Vulnerability class are Least Developed Countries.

For some of the most strongly fishery dependent countries (Benin, Chad, Comoros, Maldives,
the Republic of Korea, São Tomé and Principe) vulnerability data are not available.

The vulnerability of national economies to potential climate change impacts on fisheries was calculated combining composite indicators that evaluate the adaptive capacity of countries,
their exposure to climate change and their fisheries dependence.
The adaptive capacity indicator is calculated from indexes of health, education, governance and size of economy.
The country-specific mean surface temperature increase by 2050 for IPCC scenario B2 (local development, lower emissions) was considered as indicator of exposure to climate change.
The indicator of fisheries dependence was deduced from the national number of fishers (absolute and relative to the labour force) and landings, the income dependency on fisheries-derived
exports and per capita fish proteins as a proportion of total animal proteins consumed.
