Marine — biodiversity under pressure: Located in Signals — every breath we take › Signals 2010
10 messages for 2010 — marine ecosystems: Marine ecosystems provide key services both globally and locally, which are essential for maintaining life on our planet. However, marine biodiversity faces an unprecedented range of pressures. In recent years climate change has caused changes in species distribution and presents new challenges for marine biodiversity as oceans become more acidic.

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.

Aquaculture production (CSI 033) - Assessment published Feb 2009: European aquaculture production has continued to increase rapidly during the past 15 years due to expansion in the marine sector in the EU and EFTA countries. This increase represents a rise in pressure on adjacent water bodies and associated ecosystems, resulting mainly from nutrient release from aquaculture facilities. The precise level of local impact will vary according to production scale and techniques as well as local and regional hydrodynamics and chemical characteristics.
