Trends in nutrient concentrations in transitional, coastal and marine waters, 1985-2005: How to read the graph: About 1 % of stations in the NE Atlantic reported a significant decrease of oxidized nitrogen concentrations between 19852005, the remainder reported no change

Marine Trophic Index percentage change between 1950 and 2004: How to read the graph: The MTI for the Black Sea was about 13 % lower in 2004 than it was in 1950.

Status of marine fish stocks (CSI 032) - Assessment published Feb 2009: Most of the commercial catch is taken from stocks that are assessed. There is however a clear trend from north to south, with almost all catch coming from assessed stocks in the north to about half of the catch in the south. In the Black Sea no stocks are assessed. Of the assessed commercial stocks in the NE Atlantic, about one third is outside safe biological limits. In the Mediterranean, about half of the assessed stocks are fished outside safe biological limits.

Northward movement of marine species (CLIM 015) - Assessment published Sep 2008: Increases in regional sea temperatures have triggered a major northward movement of warmer-water plankton in the north-east Atlantic and a similar retreat of colder-water plankton to the north. This northerly movement is about 10 o latitude (1 100 km) over the past 40 years, and it seems to have accelerated since 2000. This will have an impact on the distribution of fish in the region. Many species of fish and plankton have shifted their distributions northward. Sub-tropical species are occurring with increasing frequency in European waters and sub-Arctic species are receding northwards. The rate of northward movement of a particular species, the silvery john dory, has been estimated at about 50 km/year. Changes in the geographic distribution of some species of fish have been observed and may affect the management of fisheries. Fisheries regulations in the EU include allocations of quotas based on historic catch patterns, and these may need to be revised.
