The aim of the monitoring strategy "SD2 - Non-indigenous species" is to assess the introduction and status of non-indigenous species in the pelagic and benthic realm through collection of data on their occurrence, abundance/biomass, distribution and ecological impacts. The monitoring is aimed at characterising the anthropogenic pressure and associated impacts, but the gathered data and information also allows to characterise the state of the marine environment. As shipping (ballast water and sediments) is the major introduction vector for marine non-indigenous species, monitoring is established in major ports and adjacent areas to them. Monitoring includes phytoplankton, zooplankton, phytobenthos, zoobenthos and fish. In addition, species-specific monitoring covers a few most invasive non-indigenous species, such as the round goby Neogobius melanostomus, Chinese mitten crab Eriocheir sinensis and Harris mud crab Rhithropanopeus harrisii. Data from the following monitoring programmes are exploited in this monitoring strategy: "Non-indigenous species – harbours and adjacent regions", "Non-indigenous species – abundance and biomass", "Phytoplankton species composition, abundance and biomass", "Zooplankton species composition, abundance and biomass", "Macrozoobenthos", "Phytobenthic communities", "Coastal fish" and "Off-shore fish". The main anthropogenic activities and associated pressures are dealt with in the programme "Marine and coastal activities".

The aim of the monitoring strategy "SD2 - Non-indigenous species" is to assess the introduction and status of non-indigenous species in the pelagic and benthic realm through collection of data on their occurrence, abundance/biomass, distribution and ecological impacts. The monitoring is aimed at characterising the anthropogenic pressure and associated impacts, but the gathered data and information also allows to characterise the state of the marine environment. As shipping (ballast water and sediments) is the major introduction vector for marine non-indigenous species, monitoring is established in major ports and adjacent areas to them. Monitoring includes phytoplankton, zooplankton, phytobenthos, zoobenthos and fish. In addition, species-specific monitoring covers a few most invasive non-indigenous species, such as the round goby Neogobius melanostomus, Chinese mitten crab Eriocheir sinensis and Harris mud crab Rhithropanopeus harrisii. Data from the following monitoring programmes are exploited in this monitoring strategy: "Non-indigenous species – harbours and adjacent regions", "Non-indigenous species – abundance and biomass", "Phytoplankton species composition, abundance and biomass", "Zooplankton species composition, abundance and biomass", "Macrozoobenthos", "Phytobenthic communities", "Coastal fish" and "Off-shore fish".

Data from the following monitoring programmes are exploited in this monitoring strategy: "Non-indigenous species – harbours and adjacent regions", "Non-indigenous species – abundance and biomass", "Phytoplankton species composition, abundance and biomass", "Zooplankton species composition, abundance and biomass", "Macrozoobenthos", "Phytobenthic communities", "Coastal fish" and "Off-shore fish". The main anthropogenic activities and associated pressures are dealt with in the programme "Marine and coastal activities".

The aim of the monitoring strategy "SD2 - Non-indigenous species" is to assess the introduction and status of non-indigenous species in the pelagic and benthic realm through collection of data on their occurrence, abundance/biomass, distribution and ecological impacts. The monitoring is aimed at characterising the anthropogenic pressure and associated impacts, but the gathered data and information also allows to characterise the state of the marine environment. As shipping (ballast water and sediments) is the major introduction vector for marine non-indigenous species, monitoring is established in major ports and adjacent areas to them.

As shipping (ballast water and sediments) is the major introduction vector for marine non-indigenous species, monitoring is established in major ports and adjacent areas to them. Monitoring includes phytoplankton, zooplankton, phytobenthos, zoobenthos and fish. In addition, species-specific monitoring covers a few most invasive non-indigenous species, such as the round goby Neogobius melanostomus, Chinese mitten crab Eriocheir sinensis and Harris mud crab Rhithropanopeus harrisii. Data from the following monitoring programmes are exploited in this monitoring strategy: "Non-indigenous species – harbours and adjacent regions", "Non-indigenous species – abundance and biomass", "Phytoplankton species composition, abundance and biomass", "Zooplankton species composition, abundance and biomass", "Macrozoobenthos", "Phytobenthic communities", "Coastal fish" and "Off-shore fish". The main anthropogenic activities and associated pressures are dealt with in the programme "Marine and coastal activities".

The aim of the monitoring strategy "SD2 - Non-indigenous species" is to assess the introduction and status of non-indigenous species in the pelagic and benthic realm through collection of data on their occurrence, abundance/biomass, distribution and ecological impacts. The monitoring is aimed at characterising the anthropogenic pressure and associated impacts, but the gathered data and information also allows to characterise the state of the marine environment.
